Defence potions temporarily raise your defence level by 1-8 (1 + 8% of your defence level, rounded down). They can be bought at the Warriors' Guild Potion Shop for 880 coins. Defence potions (1) can sometimes be found inside barrels. Defence potions (3) are a rare loot from a young impling or a young impling jar. A defence potion (4) is an ingredient in a Grand defence potion, one of the combination potions. Previously, during the Jekyll and Hyde random event, if a clean toadflax herb was given to Dr. Jekyll, he would give out a defence potion.
