Antipoison++

Super strong anti-poison potions are made by mixing clean irit and magic roots in a vial of coconut milk, giving 177.5 Herblore experience. It requires level 79 Herblore.

Super strong anti-poison potions cure poison, and provide the longest possible immunity to poison, at 12 minutes. That makes them far more useful than other types of Anti-poisons, as it eliminates the need to drink them constantly. However a Super antipoison gives immunity for half of the time but it cost significantly less than half, meaning a Super antipoison is much more cost efficient when inventory space is not a consideration.

This potion is rarely made through Herblore, because the ingredients cost significantly more than the finished potion. However, it is dropped from several monsters, which is enough to satisfy the low demand. For example, the Corporeal Beast drops it in stacks of 40. It is also a random PVP item drop that can be obtained by killing other players on Bounty Hunter or PvP worlds. Much of the demand for it comes from people on ape atoll, training on the guards there or doing the quest.
