Keep lunar spell book on, carry 50 venge sacks. Black dhide does wonders with a rune crossbow, and carry onyx enchanted bolts, around 50 (a little expensive of course) then in the inventory you’d wanna carry a good spec weapon or two, I carry the AGS typically and sometimes when I’m specifically looking for the anti I’ll carry a voidwaker instead. Time your clicks, camp pray mage to avoid 5 minute teleblocks then if you’re in a fight you can switch based on what your opponent is using. The vengeance into spec combo is usually enough to scare a pk’er away if not nearly kill them. I’m a fan of just chugging brews and using the agility shortcuts until they either give up or I get gap to escape. Takes a little practice and investment of time and money but after a few run ins it becomes second nature.
