Title: Bergoth the Malformed does not heal allies with his passive skill "Canister" when Ice Golem boss perform AoE attack.

Full name of your device: N/A (Ask Hell Hades)

The version of your OS: N/A (Ask Hell Hades)

Steps you performed in the game before the issue occurred.

Step 1. Include Bergoth the Malformed into a team for Ice Golem Stage 20.

Step 2. Reach to the Boss stage and attack the boss as usual. Observe when the boss perform his AoE (Area of Effect) attack with revive minions simultaneously.

Actual Result: Bergoth passive did not activate when he receives damage from enemy attack.

Expected Result: Bergoth passive should activate whenever he receives damage from enemy attack.

Refer to the video timestamp at 16:45 and 17:15 to reproduce the error.

Also, his passive does not work when he has shield buff. So even though he receives damage from enemy attack with shield, he does not heal his allies too (the mechanism seems like its copied from lifesteal) See video timestamp at 27:23
