Plant Killer increases physical and magic damage against plant monsters. The plant killer passive abilities can be found in various types of equipment, materia abilities, and unit buffs.
As with all killer passives, players can gain extra damage boosts when the units have been maxed out.
Sometimes it may be beneficial to swap in a plant killer item in place of a raw damage item that may provide little to no additional damage.
