WL Chilling Tenticles and invisibility

[Necro]

Whenever my Warlock cast chilling tenticles and they do damage to enemies, I am unable to stay invisible.  It seems that invisibility thinks chilling tenticles is my Warlock actually making an attack.  I would think this should not be the case?

I think Creeping Doom works, and some other AoE spells do that as well. I assumed this is intended behavior.

I can understand when you first cast the spell it will remove invisibility.  But once it is cast and you move away, it shouldn't remove any new invisibility you cast. 

Currently, if chilling tenticles lasts 20 rounds and it is hitting enemies, you cannot go invisible for 20 rounds even if you move to a different room.

This really seems wrong to me.
