Creates a poison cloud which deals an initial damage of 5 per hit. Total damage is 105 hitpoints (5 turns of 5 hp, 5 rounds of 4, 7 rounds of 3, 10 rounds of 2 and 19 rounds of 1) untill damage stops (when not healed).
This rune may be useful to block certain monsters in PvP worlds. However it is useless against anyone over level 10 as they can easily just use exana pox to heal themselves from the poison damage.
The poison field will last for 4:08.
