This is no kidding, I can't remember on top of my head, but my 2x level consular/master LS mastery (+3 WIS) had 41(or 42) WIS, and 20 CHA after all item/mastery/leveling modifications.
My force powers such as insanity, stasis field etc. = guaranteed success, even for Sion (but not Nihilus or Traya). Force Storm deals crazy high dmg, usually killing enemies in 1 or 2 hits. Master Heal heals about 90 HP, with absolute no loss of mana (coz mana regen just too fast, something like 6 mana/s) same goes with Master Speed.
On a side note [spoiler ??],

after I got Battle Precognition from Handmaiden, it adds WIS modifier into ur AC. When coming along with Force Armor, I get AC50. Most normal enemies cant even hit me properly, HP nvr drops
When I finished the game I have something like 3xx HP and 7xx mana.
And ya, I was stunned when I suddenly knew my character got this insanely high WIS...
