Troll thistle

Troll thistle is a quest item used in the Eadgar's Ruse quest. It can be obtained by searching the top of the hill in Trollheim above the cave where Eadgar lives.

The player can then 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, when mixed with an unfinished ranarr potion, is used to make a Troll potion.
