A Blast mine is a visible trap that explodes 30 - 5*SkillLV seconds after it is set or when an enemy steps on it, hits a 3x3 area around the target cell for [(50+DEX/2)*(1+INT/100)*SkillLV] damage.
This skill ignores DEF and MDEF and damage modification cards for size and family, but not elemental property. This trap will affect Players in PVP zones, including the user. The caster can move the trap before it's activated.
