Abyss Desecrated Ground has Super Low Visibility but is Extremely Dangerous.

Abyss Ground applies the "No regen" debuff, which can't be itemized against in any way (passive, corruption, % inc life, etc etc) for melee caracters. This is by far the most dangerous debuff in the game and is only present in PoE 1 in very specific encounter with very high visibility:
- Maven Beams
- Map Mod

This doesn't align with the game design philosophy that higher difficulty content should be more visible. As such, I'm reporting it as a bug - no way this is intentional.
