Delrith

Delrith is a monster who must be killed while doing the quest Demon Slayer. He is a level 27 lesser demon and is killed easily with Silverlight. If you are about level 25 strength, you should be able to hit a 7 on him with Silverlight. You can find Delrith outside the Southern gate of Varrock.

When you defeat him will you have to say the word combo that the gypsy told you. There will be this one and three other ones so you have to chose the right one, if you get it wrong then you will have to fight him again, if you defeat him then you will complete the quest.

Note: The silverlight is as good as the Rune longsword when it is against demons if it isn't agaainst demons then it will have its normal stats. Also, be wary of the Dark Wizards summoning Delrith, as they can attack you at a distance. If you can, have a friend hold of the wizards while you take down Delrith.
