Seele Buffs
The updates to Seele's skills and mechanics have greatly improved her viability:
steps
- Seele now gains additional skill attacks when targeting enemies below 50% HP. These attacks don't consume skill points or generate energy but can trigger Resurgence mechanics and prioritize the weakest enemy if no valid target exists.
- Her skill multiplier has been increased, along with a higher damage scaling on her ultimate.
- A stacking mechanism now increases Seele's damage dealt up to 150% when she defeats enemies, lasting three turns.
- Her speed boost duration has been extended to three turns for sustained mobility during fights.

steps
- Healing duration for her skill is now three turns, improving team survivability during extended battles.
- Healing triggers now target the lowest HP ally during turns or ultimates, ensuring efficient healing allocation.
- Allies with maximum energy above 160 receive extra energy and a higher attack buff upon Huohuo's ultimate activation.
- Huohuo is now SP-positive at E0, allowing a smoother skill rotation without dependency on Eidolons.

Welt Yang Improvements
Welt Yang's abilities and kit have undergone detailed revisions to boost his versatility and overall power:
steps

- Eidolons revamped to include critical rate and damage bonuses while lowering resistance for enemies in the weightless state.
- His effect hit rate bonus scaling with attack makes him excel as both a damage dealer and debuffer in hypercarry setups.
