How to Complete Fusion Events in Invokers: Titan Legacy

To complete a fusion event in Invokers: Titan Legacy, you must collect every designated component champion across a series of scheduled milestone challenges, level and ascend those components to exact specifications, and combine them at the fusion altar before the recipe timer expires.

Because fusion recipes are strictly deterministic, missing even a single base component breaks the chain and locks you out of the final hero.

How Fusion Event Progression Works

Fusion events require assembling lower-tier units to create intermediate champions, which then combine to unlock the final featured champion.

Earn Base Components: Win or collect the required base heroes (typically rares) by reaching point thresholds in scheduled tournaments, dungeon events, and summon milestones.
Lock Acquired Units: Immediately lock every earned component in your roster inventory to prevent accidentally using them as rank-up fodder or leveling food.
Upgrade Components: Raise each base hero to their maximum level and ascend them fully using affinity potions and elemental crests.
Fuse Intermediate Champions: Combine sets of four fully prepared base heroes at the fusion altar to create intermediate champions (typically epics).
Prepare and Fuse the Target: Level and fully ascend all intermediate champions, then submit them to the altar to unlock the final event champion.

Do not invest resources beyond the exact level and star rank required by the recipe. Extra experience, gear, or skill upgrades applied to temporary component heroes are permanently lost when the fusion is executed.

Energy Allocation Across Event Types

To complete a fusion without depleting your resources, spend energy only on activities tied directly to an active milestone tournament. Overlapping events offer the highest efficiency. For instance, clearing dungeon stages during a simultaneous hero training event provides tournament points, gear, and leveling fodder all at once.

Event Type	Primary Objective	Resource Priority	Efficiency Strategy
Dungeon Tournaments	Farm specific gear or materials	Energy refills	Run the highest reliable stage on auto-farm to maximize point-to-energy ratios.
Hero Training	Level up and rank up food units	Energy and XP potions	Save promotions and tavern leveling until milestone windows open.
Gear Upgrades	Enhance gear pieces to tier levels	Gold and mana reserves	Upgrade hoarded gear only while tournament point milestones are active.
Summoning Events	Open shards, scrolls, or summons	Summoning currencies	Pull shards until you reach the component milestone, then stop immediately.

Managing Summoning Milestones

Summon milestones represent the strictest bottleneck during a fusion schedule. Opening shards outside these active windows wastes resources needed for future milestones.

Calculate point costs in advance: Review the milestone point track to determine the exact number of shards required to unlock the component hero.
Burn low-tier currencies first: Use lower-tier shards or scrolls to reach exact point totals without overshooting thresholds.
Stop at the target milestone: Never continue pulling once the component hero is claimed. Save all remaining summoning currency for the next event cycle.
Assess alternate routes: If the schedule includes extra component fragments across difficult dungeon milestones, check whether your roster can clear those stages to reduce the number of summoning shards needed.

Final Assembly at the Altar

Complete intermediate fusions as soon as their required base components are ready. While the fusion altar interface often remains accessible for a short grace period after the individual tournaments conclude, the recipe disappears permanently once the altar timer hits zero. Fuse intermediate units early so you only need to complete the final combination during the closing hours of the event.
