it is 1 ap skill, easy to use, long ranged. And on top of that it is dealing more damage than a fireball. Fireball is dealing 45 dmg (level 5) and trap is dealing like 70 damage.
It is a way too overpowered and gives too much burst damage.
Or it seems sometimes dealing normal damage (around 30-40 like fireball) and sometimes double - probably im wrong here - didnt test it much.
Just did Judge fight at level 5 with outdated equipment - had no troubles at all with it. While my first attemp (without trap) failed miserably.

Well for the nerf i have an idea to lower it's fire damage a lot and give some phys damage aswell, So it will be some phys+ fire damage and wont burst magic armor in 1 second.
