Fire + Oil = Smoke Cloud over burning ground
Fire + Ooze = Explosion that leads to a Smoke Cloud over burning ground
The important thing is that it is these combos that result in the Smoke Clouds that hinder Line of Sight. Burning Ground on its own (without Oil or Ooze) gives off no Smoke.
Ah, the Smoke Cloud is not something I was aware off. I tested it a couple times earlier, but the behavior didn't seem consistent both times, which leads to these questions:
1) When there's a Smoke Cloud on an enemy target, can I target it with AOEs and still damage it?
2) When there's a Smoke Cloud on an enemy target and I hover my cursor over it, it will tell me the target is invisible, but if I just move my cursor around a bit, around the general area of its hitbox, I find I can still target it sometimes. What's the meaning of this?
3) How is this mechanic best utilized, since it means, maybe (see above), that you can't target the enemy? All I can think of at the moment is perhaps using it when you know a target is low on Action Points, so you force it to use AP to move out of the Smoke Cloud. But then that requires quite a bit of AP on your part to set up that it seems you might as well do something else instead.
Thanks.
