The final instant spell belonging to Druids.
It poisoned the enemy with around 200 total damage, depending on your level.
Note that the target(s) will be poisoned, it won't make full damage when you attack.
It was used a lot by druids when cleaning the Orc Fortress, it was a good strategy if you went with a team, if you didn't, it was a waste. It was also excellent to use that spell in Nargor since Pirates did not have immunity to poison.
If used against players, players could use the Antidote spell or the Antidote Rune to get rid of the poison before major damage is done. Therefore, you should never buy this spell with sole purpose of Player Killing.
