Infinity Kingdom calls its Immortal-summoning currency Philosopher Stones. The most dependable free route documented by player guides is to complete daily missions until you reach 100 activity points. Then check the Hall of Immortals for its free timers, review every active event, and watch official channels for current gift codes. Event rewards, reset times, VIP benefits and shop contents can change, so verify the counters and reward descriptions shown in your current game client.
Do not confuse Philosopher Stones with Soul Crystals. Stones and Philosopher Stone Shards are used for summons in the Hall of Immortals; Soul Crystals are a separate currency used for Market purchases and Immortal skill functions.
Use the game’s exact currency name
Searches often call the item an “Immortal Summoning Stone,” but the publisher’s building guide names it a Philosopher Stone. The same guide says Philosopher Stones and Philosopher Stone Shards are used to summon Immortals in the Hall of Immortals. That terminology matters when you are looking through menus, event descriptions, mail, codes and community posts: a search for the informal name can make a real reward appear to be missing.

- Philosopher Stones: the full stone currency used for the Hall of Immortals’ stone summons.
- Philosopher Stone Shards: a shard-based resource used for separate summon attempts.
Soul Crystals are not another name for either item. Publisher material describes Soul Crystals as a currency for Market purchases and skills. Some older player guides discuss earning or converting Soul Crystals after summons, but those mechanics do not mean that farming Soul Crystals directly increases your Philosopher Stone balance.

The most reliable free routine
1. Finish daily missions to 100 activity points
Two 2022 player guides hosted on the GTarcade Infinity Kingdom forum identify daily missions as the clearest recurring free source. Their documented threshold is 100 activity points for one Philosopher’s Stone. One guide describes daily missions as the easiest way to obtain a free stone; the other says the stone is awarded after completing enough missions to reach 100 activity points.
Because those guides are from 2022, treat the number as a documented reference rather than a guaranteed 2026 rate. Open the daily-mission screen in your account and check the activity milestone, the reward icon and the claim state before assuming the reward has changed or disappeared.
- Open the game’s Daily Missions or daily-task screen.
- Review the activity milestones and note which tasks are practical for your account.
- Complete enough tasks to reach the displayed stone milestone, historically 100 activity points.
- Return to the activity-reward track and claim the Philosopher Stone if the interface requires a manual claim.
- Check your inventory or Hall of Immortals summon balance to confirm that the stone was credited.
A 2022 guide states that daily tasks reset every 24 hours at 00:00 UTC. Reset behavior can be changed by a game update, server region or interface redesign, so rely on the countdown or reset notice displayed in your client. If you play near the reset, finish and claim the activity reward before the timer expires; an unclaimed milestone may not carry over.
Recommended Free Tools
2. Use the Hall of Immortals’ free attempts
GTarcade’s official building guide, published in 2020, documents one free Philosopher Stone summon every 24 hours and five free Philosopher Stone Shard attempts per day. These are free summon opportunities rather than extra stones necessarily added to your inventory. The guide is old, so check the live Hall of Immortals screen for the current counters, cooldown and claim button.
- Open the Hall of Immortals.
- Look for a free stone summon or a countdown showing when it becomes available.
- Use the free attempt when the timer is ready; do not spend a stone if the interface is offering a free attempt.
- Check the shard summon section separately and use any displayed daily shard attempts.
- Record the next reset time if you are trying to maintain a daily streak.
Free attempts can be easy to overlook because they may appear as a timer or a small “free” label beside the summon controls. A full inventory does not replace the need to open the Hall: the free-attempt counter and the stone balance are separate things.

3. Check the event calendar and reward pages
Older player guides recommend monitoring the in-game event calendar because limited-time events can award Philosopher Stones, shards or summon-related items. Events rotate, and the available reward is not stable enough to promise a particular quantity or schedule.
When an event is active, inspect both the overview and the detailed reward track. Some rewards are granted automatically; others require you to tap a milestone, exchange event tokens or finish a ranking period. Confirm:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- the event’s start and end time in your server’s displayed time zone;
- the exact task or score needed for the stone reward;
- whether the reward is a full Philosopher Stone, shards or another currency;
- any account-level, kingdom-age or participation requirement; and
- the deadline for claiming an earned reward.
Do not plan your monthly stone income around an event that is not visible in your current calendar. A guide written in 2022 cannot establish that the same event, task or reward is running now.
4. Review current gift-code announcements
A 2022 player guide says weekly gift codes often included Philosopher Stones. That cadence is not established as current, and old codes may be expired, region-limited or already redeemed. Look for codes in the game’s current announcements and official community channels, then use the redemption path shown by the game rather than copying a code from an undated list.
Before redeeming a code, check its expiration date, capitalization, server restrictions and one-redemption-per-account rule. If a code is rejected, capture the exact error and verify that you are using the current account or character. Never treat an unverified code list as a guaranteed source of stones.

Which routes are free, recurring or conditional?

How to spend stones efficiently
Consider the ten-piece advanced summon only when the discount is visible
An older player guide says an advanced summon of ten pieces costs nine Philosopher Stones, describing that as a 10% discount. This is an efficiency tip, not a permanent rule. Summon interfaces, event banners and costs can change, and a limited-time summon may use different requirements.
If your current Hall of Immortals screen shows the same nine-for-ten offer, saving until you can use the discounted threshold generally gives more summon pieces per stone than repeatedly making single attempts. Before waiting, consider your actual objective:
- Save for the discounted bundle when you are pursuing long-term summon value and the offer has no expiration.
- Use a single attempt when an event requires immediate progress, a guaranteed milestone is about to expire, or the current banner has a reward you specifically need.
- Read the banner’s rules each time; never assume that an older advanced-summon discount applies to every summon type.
Write down the displayed cost and the expiration time of a limited offer. That prevents an apparent saving from turning into a missed event reward.
Why Soul Crystals should not be counted as stones
Soul Crystals can be useful, but they are a different resource. Publisher material associates them with Market purchases and skill unlocks or upgrades, while Philosopher Stones and shards are the Hall of Immortals’ summon currencies.
An older 2022 player guide describes a sailing route that, after Chronicle 19, takes around 12 hours per trip and yields about 1,000 Soul Crystals per trip. The same guide claims that an account above 140,000 power could obtain more than 1,800 Soul Crystals every two days. Those figures are historical player-guide claims about Soul Crystals, not a Philosopher Stone drop rate. They should not be used to calculate how many stones you will receive.

- Hall Effect Joysticks and Triggers
- Refined bumpers and D-pad. Light and tactile.
- 2 Pro back paddle buttons
- Profile button. Wear-resistant metal joystick rings. Turbo function.
If a summon, exchange or conversion screen offers Soul Crystals, read the exact output before confirming. The conversion quantities and eligibility rules discussed in older guides need current verification, and possessing Soul Crystals alone does not satisfy a Hall of Immortals stone requirement.
VIP benefits and paid offers
VIP chest
The 2022 player guide reports that VIP 10 accounts received an additional daily Philosopher Stone in a Daily Exclusive Chest. This is account-dependent and may have changed. Open the current VIP or daily-chest panel and check the displayed VIP level, reset time and reward contents. Do not upgrade solely on the basis of an old guide’s description.
Bundles and the in-game shop
Historical guides mention daily bundles containing Philosopher Stones and Mystery Pearls, but their old prices and contents are not a reliable basis for a present purchase decision. If you are willing to spend, compare the live bundle’s stone count, bonus items, purchase limit, reset period and expiration against the summon cost shown in your Hall of Immortals.
For a free-stone question, paid bundles are optional rather than a required step. There is no stable, current evidence that one bundle is the best value for every account, server or event.
A practical daily and weekly checklist
Every day
- Open Daily Missions and identify the shortest path to the displayed activity milestone.
- Reach the stone threshold shown by your current activity track; older guides cite 100 points.
- Claim the activity reward instead of assuming it was delivered automatically.
- Open the Hall of Immortals and use any free stone attempt whose timer is ready.
- Check the shard section for the displayed free-attempt counter.
- Review active event pages for stone, shard or exchange rewards.
- Open any current VIP or daily chest if your account qualifies.
At each weekly reset or event change
- Read the new event calendar rather than relying on last week’s schedule.
- Check official announcements for a currently valid gift code and its redemption deadline.
- Review the Hall of Immortals’ summon banners for any displayed multi-piece discount.
- Clear expired notices and recheck your inventory so stones and shards are not being confused.
What to do when a stone seems to be missing
You reached the activity target but received nothing
Reopen the activity-reward track and look for a claim button. Then verify the stone count in the Hall of Immortals rather than only in a general mail tab. If the target or reward shown in your client differs from 100 points, follow the live display; the 100-point figure is from a 2022 guide.

The free Hall attempt is unavailable
Check whether the countdown has actually finished, whether you already used the attempt during the current server day and whether you are viewing the stone or shard summon tab. The official count of one stone attempt and five shard attempts is from 2020, so a different current counter may be intentional.
An event reward cannot be claimed
Read the event’s eligibility and claim deadline. Ranking rewards may be delivered after the event closes, while milestone rewards can require a manual tap. Also confirm that the item is a Philosopher Stone and not shards, Soul Crystals or an event token.
A gift code fails
Check spelling, capitalization, expiration, server restrictions and whether the code was already used on the account. If the announcement does not come from a current official channel, assume that the code may be obsolete until confirmed.
How to verify the live rules in your client
Because the strongest numerical claims available for this topic come from a 2020 official building guide and 2022 player guides, the game interface is the final authority for your account. Use this short verification pass whenever the game updates:
- In Daily Missions, record the current activity threshold, reward and reset countdown.
- In the Hall of Immortals, record the free stone timer, shard-attempt count and each summon cost.
- In Events, open the detailed reward page and note the exact stone or shard conditions.
- In VIP and daily-chest panels, confirm the level required for any extra stone.
- In the redemption screen or current announcements, confirm code validity and expiration.
- Check your inventory after claiming a reward so you know whether it delivered stones, shards, Soul Crystals or an event item.
Infinity Kingdom remains actively updated, with publisher updates listed as recently as September 2026, but an update date alone does not establish a current stone reward table. Recheck these screens after major patches, server-age milestones and event rotations.
