We're happy to see Mathilda back in action, but she was buffed a bit too much, so we're nerfing some aspects of her Ultimate to make her easier to counter.

Angela
Angela hero Nerf

Compared to other "backline Supports", Angela can benefit more from equipment with Magic Bonuses because she can attach to teammates to avoid taking damage. So we're nerfing the Magic Bonuses for her skills.

Wanwan
Wanwan hero Nerf

Adjustments applied to Tiger Pace.

All Documented Modifications (2)
Designer Note
We reduced Wanwan's dash speed in the last few patches to make it easier for her opponents. However, since we increased the cooldown of her control removal ability, the dash speed nerf seemed unnecessary. So we're reverting Wanwan's dash speed change to improve her gameplay.
Increased how much Wanwan's dash speed increases with her Attack Speed to bring it in line with the pre-nerf version.
Role: Marksman

Arlott
Arlott hero Nerf

Arlott's opponents now have enough time to react to his Ultimate after we increased the skill's animation time, so we are reverting the rest of the previous nerf.

Aldous
Aldous hero Buff

Adjustments applied to Contract Soul Steal, Contract Chase Fate.

All Documented Modifications (3)
Designer Note
After the last adjustment, we found that Aldous' stack building speed has been significantly improved. But also noticed that players wanted him to be more powerful in the late game, so we buffed him based on feedback. Combined with the Twilight Armor adjustment, we think Aldous should be well balanced now, but we'll continue to monitor his performance.
