Enemy 'molten core' attacks are OP

Some enemies, like Heorot (timeline boss) and Logi the Three Shamans (timeline boss) have a molten core attack, where they spawn a rolling ball of lava. For Heorot, it’s an ice ball. I believe some non-boss enemies may have it too. But this ability is:

  1. Not telegraphed at all, audibly or visually.
  2. Appears out of thin air
  3. Has one-hit kill potential
  4. Is often used completely ‘off-screen’
  5. Fast moving

Either nerf the damage so that it can’t one-hit kill, or give it an obvious telegraph so that it can be avoided, or slow down its movement speed so that it can be avoided. Right now, it’s the most annoying enemy attack that I can think of because there’s no way that I’m aware of, for me to ‘out skill’ the attack.

Most of my negative experience with this enemy attack has occurred at 400-500 corruption for reference.

Not to mention the other issues with Heorot and Logi, both these bosses have attacks and mechanics that need to be redesigned. Heorot is buggy af, he constantly one-hit kills with what I can only describe as invisible effects, and he constantly gets himself stuck in a corner or against a wall then does arena-wide AOE effects which are really annoying when he’s up against a wall and the only safe zone is a bubble around him. Logi’s AOE puddles on death of one of three shamans, and mortar attack, and not being able to be pulled by abilities like warcry make it a very unfun fight compared with many of the other timeline bosses.
