Tormented demons (TD's) are one of the strongest monsters in the game. TD's boast some of the most unique combat mechanics of any monster in runescape where you will actively need to switch attack weapons, gear, and protection prayers to be successful in the hunt. They are 450 combat, require actual strategy and timing but the rewards can be worth the trouble.
When fighting Tormented demons you will have to use the Darklight (melee) or Holy water (ranged) to weaken the demon before you can damage them with your main weapons. Which you use is dependent on the protection prayer the TD is currently using. Example: if they are praying melee/magic, you would use Holy water to lower the shield.
You may purchase the Darklight and Holy water from the shop placed on your way to the tormented demons. Currently the stock is 1 Darklight and 100 Holy Water for 500 GP and 1 GP respectivly. I would recommend buying multiple Holy Waters.
