Requirements Create Deadly Poison Lv. 1

Enchant Deadly Poison consumes one Poison Bottle (created with the Create Deadly Poison skill) and enchants a weapon with deadly poison to increase its damage potential. This skill does not change the weapon's attack property. Skill level affects damage increase, duration and SP consumption. There is a chance to cause a more severe version of the poison status effect on enemies as you deal damage with all levels of this skill. This poisoning aspect of the skill does not work against Boss Protocol monsters, as they are immune to status effects.
