i have notices. the spell in runeword backfires on the user. and in most cases so does the effects. you i been testing runewords right and left. i use scractchers in dragon/spider epics and got more criticals/severs on me then i can sever the epic creatures. and each new runeword i find needs to be look at. because i made 1 and it backfire every time i thrust. effect like "Of The Squire" are not effected both ways. because the complexity for you and the mobs. only 1 matters and that you and your complexity. if the mobs has the extras complexity it doesnt matter.
In any case all the runewords need to be check and testing out. i think this is a huge bug on runewords for battles, effects, and others.
The reason i posted here is that we need to test out all the runewords and new ones that pop up. i realize we have more 200 runewords for the caretaker to test out. it need to be done. legbiter, scratchers,Chicken fury, Witch hunter and all.
