I had a project like 8 years ago to create a similar staff with 30+ mods because in single player and open bnet inserting the last jewel crashed the game.
Unfortunately it did not work on BNet, I believe servers have different tolerance.
I remember searching for an eth superior war staff with 3 skills, and the apropriate jewels (ED+AR vs demon, ED+AR vs undead and stuff like that). I offered thousands of FG for those.
