It allows you to attach explosive trap to enemies with melee attacks, but it only triggers once every 1.5 seconds, can only apply one trap per enemy and has a set arming time that isn’t affected by other nodes. If you could apply it multiple times maybe with a high mana cost it might make a fun melee build. But right now it seems far to limited, at least compared to some of the other nodes like the bow conversion node.
Im actually using it with my cinder build falconer (didn’t find the unique gloves yet). Quite easy fix and buff would be that yes it can happen only once every 1.5 seconds, but it applies to all enemies hit by it (which is still not much unless you go absolutely crazy with area effects idols). I combine it with nodes that trigger side traps and acid flasks. Its OK but i didn’t experiment too much with other variants yet.
I think if the cooldown were modified by your attack speed that would make it nicer.
