Weapon poison++ is made by using cave nightshade on a vial of coconut milk and poison ivy berries. Cave nightshade only spawns inside the Skavid caves and is not tradeable, so the spawn time of the nightshade is the limiting factor in how fast weapon poison++ can be made.
Cave nightshade can be found in the caves under Gu'Tanoth, east of Castle Wars. The easiest way to get there is by teleporting to Castle Wars with a ring of duelling and walking to the most northern cave entrance, marked on the map to the right. A skavid map and a light source are required to enter. Gloves are required for picking Nightshades.
Collectors can wait due to the fast respawn rate, which means that you can afk while doing this.
