Talk:Tenser's Transformation/@comment-183.178.120.125-20180602161409

If you're casting tenser's transform using arcane scroll (either for theif with UAI, or mage), your base THAC0 is fixed at 9 with the bonuse +2 to hit from the spell. It is equivalent ONLY to a lv.12 figter's THAC0. Even though your thief or mage is much higher level than that, say lv.20+ or 30+, you still get only base THAC0 = 9...

It seems to have something to do with the direct casting a spell using arcane scroll is treated at a fix level regardless of your character's level.

Kind of suck for high level thief who want to improve the base thac0.
