I added the info that Tenser's affect number of arrows shot but it was reverted due to it being "obvious".
BAB article claims this value "comes purely from his or her profession, training, and personal experience", and Tenser's Transformation does not mention it affecting BAB based attacks, although I can't think of many other than Many Shot.
Not sure where I should put this info, because when my Tenser ranger used multi-shot, I was surprised by the extra arrows and tried looking it up, but it wasn't clear that Tenser will assist Many Shot based on Wiki info. ZirePhoenix (Contributions • Message) 13:18, September 11, 2014 (EDT)
How much does Tenser's improve your Manyshot?
The BAB bonus from Tenser's Transformation is dependent on your class selection. If you picked Ranger 6/Wizard 6, your BAB will only be 9, but while under the effects of Tenser, your BAB will be 12, which will let you shoot three arrows.
