LOL!
Hell Plant:The cast of this skill is full variable.
Range of Plants is 1 cell, therefore it is most effective when cast on the target or 1 cell next to the target.The damage is considered magic damage, irreducible for soft MDEF and hard MDEF, and isnt miss in a gtb wearer.
In WOE, Plants disappear (without doing any damage) if guildmates step on it. Your own homunculus can destroy also Plants, taking no damage from them.
The caster is the only one who can step on the Plants, without destroying them.
In PVM/PVP, Plants deal 100 % damage.
In WoE, Plants deal 50 % damage.
Placing as many plants as possible around the caster provides excellent defense against melee attackers in WoE. For example: a Gfisting Sura.
Plants can not hit ghost property enemies.
Plants are stackable there is no known limit to how many can be stacked on a single cell.Plants last about 35 seconds, then disappear.
Plants damage is not decreased by Assumptio.
Success rate of Stun and Bleeding is decreased by stat immunity and level difference as usual.
Safety Wall blocks Plants' damage as usual and will disappear if the Plants out damage the wall's "HP".
Energy Coat reduce Plants' damage in 30%.
