Infinity Tower

Tower Overview

The Infinity Tower is a permanent endgame solo/duo challenge mode consisting of 100 floors. Each floor is a self-contained combat encounter with its own enemy composition, mechanics, and rules. The tower resets every Monday at 00:00 server time — players begin from floor 1 each week and climb as high as possible, earning milestone rewards and a weekly chest based on their personal best floor that week.

The Tower is accessible from Level 40 onward, but practical progression past floor 50 requires Level 70+ gear. Duo mode (2 players) applies a ×1.6 HP multiplier to all tower enemies, slightly less than the ×2 you might expect, making duo marginally easier per-player than solo — but coordination overhead negates much of that advantage at high floors.

Tower progress is not saved between sessions. If you exit the Tower mid-run, your personal best floor for the weekly chest is preserved, but you must restart from floor 1 in the next session. Plan tower sessions as a single committed run.

Floor Types

Every set of 10 floors follows a fixed pattern. Within each 10-floor segment, three floor types appear:

Puzzle floors reward an extra Essence Fragment for solving the puzzle optimally (completing it within the challenge condition). Failing the puzzle condition still allows you to proceed to the next floor, but without the bonus reward.

Milestone Rewards

Milestone rewards are granted once per account, per week, upon first reaching each floor threshold:

Weekly Chest

At weekly reset, every player receives a Weekly Tower Chest based on their personal best floor that week. The chest tier scales with floor reached: Bronze Chest (floors 1–24), Silver (25–49), Gold (50–74), Platinum (75–89), and Apex Chest (90–100). The Apex Chest contains 1–3 Apex materials, a guaranteed Legendary item, and a 5% chance of an Apex gear piece.

Token Shop

Tower Tokens are earned from milestone rewards and puzzle floor bonuses. The Token Shop opens at floor 50 cleared (lifetime unlock, not weekly). The shop sells:

• Void Shard Bundle (×10) — 30 Tower Tokens
• Essence Fragment Bundle (×10) — 25 Tower Tokens
• Random Epic Gear — 50 Tower Tokens
• Random Legendary Gear — 150 Tower Tokens
• Tower-Exclusive Cosmetic (rotating monthly) — 200 Tower Tokens
• Prestige Shard — 80 Tower Tokens (Prestige 1+ only)

Difficulty Scaling Formula

Enemy stats in the Tower scale per floor using the following base formula:

Boss floors additionally apply a ×2.5 HP multiplier and a ×1.8 ATK multiplier on top of the floor scaling. This creates dramatic power spikes at floors 50, 80, 90, and especially 100, which has unique boss mechanics not found elsewhere in the game.

Strategy by Bracket

Floors 1–50 (Accessible Content)

Any Level 60+ character with Rare gear can reach floor 50. Focus on clearing wave floors quickly — the Tower has no timer per floor, but your stamina and skills reset between floors, so there is no efficiency cost to being methodical. Use the floor 25 puzzle to practice reading mechanic cues, as later puzzles follow similar logic. At floor 50 boss, prioritize DEF stacking to survive its three-phase assault.

Floors 50–80 (Endgame Entry)

Requires Level 80 with Epic+ gear. Enemy HP pools here are substantial — sustained DPS builds (Pack Warrior, Dark Knight) outperform burst builds (Shadow Rogue) because the time-to-kill is long enough that sustained output wins. Lifesteal becomes increasingly valuable from floor 65 onward, where enemy ATK can outdamage healing regen from passive sources alone.

Floors 80–100 (Prestige Requirement)

Practical minimum: Prestige 1 with Legendary or Apex gear. Near-optimal builds (Blood Mage with max AP stack or Pack Warrior with maximum STR and Prestige 5) are needed for floor 95+. The floor 100 boss has a full unique mechanic set not previewed on any other floor — its Phase 2 reverses all lifesteal effects to damage for 3 rounds, making high-lifesteal builds temporarily dangerous at that phase transition.

Floor 100 — Eternal Night Cloak

Completing floor 100 awards the standard floor 100 milestone loot plus a 0.15% chance to drop the Eternal Night Cloak — the rarest item in the game. The Cloak is a legendary-tier cosmetic cloak with unique animated particle effects (shifting moonlight and blood mist) and a +50 HP passive stat bonus. It cannot be traded, sold, or transferred between characters.

Players who complete floor 100 receive the permanent title "Tower Conqueror" displayed beneath their character name in all game modes. This title does not reset with the weekly tower reset — it is a lifetime achievement.

Best Builds for Tower

• Blood Mage (floors 1–80): Highest burst per floor for wave clears. AP scaling dominates early floors where enemy DEF is low. Weakness: low HP makes floor 75+ boss phases dangerous without Lifesteal support items.
• Dark Knight (floors 50–100): Best sustained survivability. High DEF + Lifesteal creates a self-sustaining loop that allows longer fights on boss floors. Slower wave clears but most consistent for reaching floor 90+.
• Pack Warrior with Prestige 5 (floors 80–100): The current consensus best build for floor 100 completion. STR × 1.5 multiplier + Prestige 1.10× = massive ATK scaling. Requires Legendary or Apex weapons to achieve the ATK threshold needed for floor 95+ boss phase DPS checks.
• Moon Warrior (all-around): Balanced DEF and ATK makes Moon Warrior the most forgiving Tower build for players still optimizing their gear. Floor 70 is reliably achievable without perfect itemization.
