So I am doing DT and Dessous (the vampire) is dominating me, i tried mage with lunar armour, using wind blast. Then I tried melee with dragon scimy wearing rune plate, d legs, sq and boots, neiz helm. He just does a lot of damage while i do very little. I was wondering what is a good way to do this.

You shouldn't have too much of a problem, mage him while using Protect from Melee. Air Wave will work best.

Yeah your stats look fine. I killed him with an even lower mage level and only use wind bolt with chaos gloves (I hear lower level spells are more accurate)

 

 

 

Otherwise, just make sure you're out of melee range while you're attacking him and use melee protect, but don't safespot. As for food, I suggest you bring pizzas as they're cheap by comparison and heal a nice amount. Get a mage potion if you want to be a little more accurate.

Thanks for the advice i just beat him
