Illuga's 60-energy Burst is among the cheapest in the game, making ER investment minimal. The Skill produces 4.5 particles per cast, giving solid self-energy generation and reducing team ER requirements.

Illuga presents a unique challenge in the current meta: a 60 Energy Cost Burst with a short 15-second Cooldown.
While 60 sounds manageable, Illuga generates 3-4 Geo Particles via his Elemental Skill but absorbs them while swapping off-field.
In a standard rotation, absorbing particles off-field applies a coefficient of roughly 0.6x to energy gains, inflating his energy needs significantly higher than on-field DPS characters with similar costs
Key Takeaways
- 60-cost Burst, 15s cooldown. Sounds manageable but off-field absorption penalizes gains.
- Off-field penalty: ~40% energy collection penalty. Flat energy refunds become critical.
- C1 breakpoint: reduces effective Burst Cost from 60 to 48, lowering ER requirements by ~35%.
- At C0, Favonius Lance is mathematically mandatory for Double Geo teams.
- Generates 3-4 Geo Particles via Skill but absorbs off-field (0.6x coefficient).
