The real tier list starts with resources, not rarity
Pocket Gamer updated its Infinity Kingdom tier list on July 17, 2026 for version 2.9.7, which makes the timing useful for new and returning players trying to decide where to spend their first meaningful batches of resources. The tension is familiar to anyone who has played a mobile strategy game with hero collection: the roster is wide, the best-looking Immortals are not always the easiest to build, and a bad early investment can slow your kingdom long before it ruins a battle report.
Infinity Kingdom’s own community wiki defines Immortals as the summonable heroes players level up and use to attack while assigned to a unit. That sounds simple, but the upgrade economy is where the decision becomes strategic. Perfcore’s 2026 review describes Infinity Kingdom as a free-to-play game with in-app purchases, where progression is tied to building upgrades, collecting and leveling Immortals, and growing military power. It also notes that hero acquisition uses summoning mechanics, adding chance to the process of obtaining top-tier Immortals.
That is the frame for this Infinity Kingdom guide. A pure damage ranking is less useful early than an investment ranking. The best Immortals in Infinity Kingdom are the ones you can obtain, upgrade consistently, fit into your first serious troop, and keep relevant long enough to justify the resources. Pocket Gamer’s advice lines up with that approach: invest in a small number of good Immortals, think ahead about the teams you want, and consider whether you are playing free-to-play or spending.
GameLoop investment tiers for new and returning players
This Infinity Kingdom tier list is built around investment priority rather than unsupported claims about exact late-game damage charts. The source material supplied here confirms acquisition routes for several Immortals through the Infinity Kingdom Wiki, and it confirms broader upgrade advice through Pocket Gamer and Perfcore. Where an Immortal’s long-term combat ceiling is not documented in the supplied sources, this guide treats access, repeatability, and account economy as the deciding factors.
S-tier investment priority goes to Immortals with broadly useful acquisition paths that a developing account can plan around. Yoshitsune belongs here because the wiki lists Advanced Summon, the Market once unlocked, Mysterium, and Alliance Shop Level 9 as acquisition routes. That spread matters because a player who misses one source still has other paths to fragments or access. Harald III also belongs near the top for practical early planning, with the wiki listing Advanced Summon, the Market once unlocked, and the Arena Insignia Shop. For players trying to build without leaning on paid bundles, those repeatable routes are valuable.
A-tier investment priority covers powerful-looking or desirable Immortals whose listed acquisition routes create more pressure on spending, timing, or shop access. Merlin is a special case. The wiki says a free Merlin is awarded on the first in-app purchase made on a character, and also lists the Market once unlocked and VIP 5 to 9 as routes. That makes Merlin a high-priority option for players who already intend to spend, but a weaker first target for a strictly free-to-play plan. Attila the Hun also sits in this practical A tier because the wiki lists the Market as gem-only once unlocked and the Arena Seasonal Reward, which suggests more timing and currency constraints than the broadest S-tier targets.
B-tier investment priority is where I would place Immortals whose source text points toward narrower access. Ramesses II is listed on the wiki with Special Bundles and a gem-only Market route once unlocked. That does not make Ramesses bad. It means a new player should be careful before building a whole early plan around an Immortal whose documented paths, in the supplied source, lean toward bundles and premium currency. In a resource-constrained game, that distinction can matter as much as raw power.
Best Immortals Infinity Kingdom players should prioritize first
For a fresh or returning account, the safest first targets from the supplied data are Yoshitsune and Harald III. The reason is not that the available sources prove they outdamage every other Immortal. The reason is that their listed paths support the most important rule in early Infinity Kingdom: pick a core and actually finish building it.
Yoshitsune has the cleanest practical case among the Immortals shown in the wiki excerpt. The wiki identifies Yoshitsune as a ranged Bowmen Immortal and lists four sources: Advanced Summon, Market once unlocked, Mysterium, and Alliance Shop Level 9. That combination gives a player several account systems to work through. If you are active in an alliance and keep progressing through shops and events, Yoshitsune is the kind of Immortal whose investment plan can survive bad summoning luck better than a bundle-gated pick.
Harald III is another strong early anchor from an economy perspective. The wiki lists Harald III as a Water, Epic, Attack-position Shieldmen Immortal obtainable from Advanced Summon, the Market once unlocked, and the Arena Insignia Shop. For a player following Pocket Gamer’s advice to stick to one troop at the beginning, Harald III offers a clear identity: he is tied to Shieldmen, has an attack role, and has multiple listed acquisition routes. That makes him easier to recommend as a first serious project than an Immortal whose access depends on seasonal rewards or premium-only channels.
Merlin is the dividing line between free-to-play planning and paid acceleration. The wiki’s note that a free Merlin is awarded on the first in-app purchase is important because it changes his practical tier depending on the player. If you are willing to make that first purchase and engage with VIP or Market routes later, Merlin can be an early centerpiece. If you are trying to stay free-to-play, building your opening roadmap around him is riskier based on the listed acquisition information.
The first troop rule is the most important meta lesson
Pocket Gamer’s most useful tip for new players is to stick to one troop at the beginning, boost that troop everywhere possible, and use it across content. That advice should shape how players read any Infinity Kingdom best heroes list. A scattered roster of individually strong Immortals can still underperform if the account’s troop upgrades, equipment, and development choices are spread too thin.
That is why this guide ranks investment fit over star-chasing. If your first serious troop uses Shieldmen, Harald III’s listed role and acquisition routes make him a sensible priority. If you are building around Bowmen and have access to Yoshitsune’s sources, he becomes an efficient long-term target. If you spend and unlock Merlin through the first-purchase path described by the wiki, your calculus changes again.
The bigger lesson is that players should avoid treating an Infinity Kingdom tier list as a shopping list detached from their account. Pocket Gamer explicitly warns that free-to-play players have a tougher time selecting a handful of Immortals to invest in, while premium players have an easier path. That difference is not cosmetic. A spender can chase harder-to-access Immortals and recover from a failed plan faster. A free-to-play player needs reliable fragment routes and a narrow upgrade focus.
Summoning discipline beats panic pulling
Pocket Gamer’s summoning advice is direct: always summon ten times rather than doing individual summons. The outlet explains that once players collect nine Philosopher’s Stones, they can summon ten times, effectively getting ten pulls for the cost of nine Stones. Pocket Gamer also states that this guarantees one Elite or Epic unit within the ten units pulled.
That has two consequences for anyone using this Infinity Kingdom tier list. First, do not drain Philosopher’s Stones one at a time because impatience can cost you long-term value. Second, treat every ten-pull as part of a broader acquisition plan rather than a verdict on your account. Perfcore’s review notes that summoning introduces chance into obtaining top-tier Immortals, so a smart plan needs fallback routes through shops, alliance systems, arena rewards, or the Market where available.
This is also where returning players should audit their roster before spending again. If you already have fragments or partial progress toward an Immortal with several listed sources, finishing that project may be better than chasing a new name. The lab system described by Pocket Gamer offers some forgiveness because players can reborn heroes once the lab is available, but that should not be treated as permission to invest randomly. Reborn systems reduce regret. They do not refund the time lost from a poorly focused opening.
How free-to-play and spending players should rank the same Immortals differently
A free-to-play player should rank accessibility almost as high as battlefield strength. Based on the supplied wiki data, that pushes Yoshitsune and Harald III upward because their listed acquisition routes include systems outside direct bundles. Yoshitsune’s Advanced Summon, Market, Mysterium, and Alliance Shop Level 9 routes create a more flexible plan. Harald III’s Advanced Summon, Market, and Arena Insignia Shop routes also give a developing account several ways to work toward him.
A light spender can move Merlin up sharply. The wiki says a free Merlin is awarded on the first in-app purchase made on a character, which means the first purchase can immediately change roster planning. Players who are already comfortable spending should evaluate whether that early Merlin access fits their intended troop direction and broader upgrade path. Players who are not spending should avoid pretending that the same recommendation applies equally to them.
Higher spenders can afford to consider Attila the Hun and Ramesses II earlier, but the listed routes still matter. Attila’s wiki entry includes a gem-only Market route once unlocked and Arena Seasonal Reward access. Ramesses II is tied in the supplied wiki excerpt to Special Bundles and a gem-only Market route once unlocked. Those paths may be perfectly acceptable for players who budget for premium currency or bundles, but they are weaker first recommendations for anyone trying to conserve resources.
A practical ranking to follow today
For most new players, the practical order is simple: build one troop, prioritize Immortals with repeatable access, save Philosopher’s Stones for ten-pulls, and join an alliance early. Pocket Gamer also advises joining an Alliance and waiting for Alliance help before using speedups, which fits the same economic logic. Early Infinity Kingdom progress is shaped by compounding efficiencies. Small waste becomes large delay.
Our current GameLoop investment ranking from the supplied source material is Yoshitsune and Harald III as the safest first priorities, Merlin as a top choice for players making a first purchase or engaging with VIP and Market routes, Attila the Hun as a valuable but more timing-sensitive project, and Ramesses II as a lower early priority unless bundles or gem spending are already part of your plan.
That ranking should not be read as a permanent combat verdict on every Immortal in Infinity Kingdom. It is a resource-first Infinity Kingdom tier list for players deciding where to invest first. If future patch notes, official balance changes, or updated public listings alter acquisition routes or Immortal performance, the rankings should move with them. For now, the best Immortals Infinity Kingdom players can chase early are the ones that let an account grow cleanly instead of forcing it into a costly rebuild.
