Hurl the Gunpowder Trap, which has a 5 meter area of effect and causes enemies who fall into it to suffer explosion damage.
Enemies within the trap suffer continuous damage, and if they are debuffed with the Wronged Ghost state, they suffer even greater damage per stack of it.
Using hidden weapons of this set afterward will add the Scald effect to them for added damage.
The trap lasts for 20 seconds and has a 20-second effect once triggered. Upgrade hidden weapons skills to increase Burn damage.
Ghost Prison: Increases the radius of the trap by 1 meter, and when the trap explodes, it will blow up to 5 non-parry targets within the trigger range.
