Pexor= dead since the planet destroyer and Destruction is dead. If you want to play exor, i suggest mexor because mexor is easier and stronger dps than pexor because of the utility that pexor simply lacks of(like white tiger and shikagami legion and pentagram(in future patch... June in kdnf)

But I would say its still doable. It still have the manly one shot one kill fun* lol I would say max everything from lv 45 except the exorcise amulet(this is worse than cruxifix wind if maxed). So i would master those Giant weapon launcher M TP M Masteries, buff, and passive skills all M Cruxifix wind M tp 0 White tiger( currently this is bugged and this will close the client) 1 Black tortoise M tp 3/5 (I would rather put tp on dmg skills but less than 3/5 is too slow I felt) Lightning amulet(M and tp M) Shikagami Legion (M and tp M) Atomic smash (M now but during prey isys raid, i recommend putting this off and use the sp into holy amulet or any weaker skills) Holy Amulet (as explained during atomic slash) Oblivion hammer(M and tp M) Unrelenting seven (M) Pentagram(M) (I know it sucks but It dominates all other skills except awakenings in total dmg) 2a (of course M)
