Troll thistle

Troll thistle is a quest item used in the Eadgar's Ruse quest. It can be obtained by picking it in any of the grass areas in Trollheim near the cave where Eadgar lives. Note that every time the thistle is picked, it spawns in a different grass patch.

The player can use the thistle on a fire to dry it out, turning it into a dried thistle. This can then be crushed in a pestle and mortar to make ground thistle, which can be used with an unfinished ranarr potion to make a troll potion. If the thistle is dropped, it will disappear and the player receives a message in their chatbox saying "The Troll Thistle withers away as soon as it hits the ground."
