Wow, go Voda Vosa!!
Is there a record for the highest self increase to defenses? If so, I think Crag may have a shot at it. In Fire and Ice, he used Second Wind and and AP for Total Defense, which boosted his AC from 20 to 29 and increased each of his other defenses by 4. That's an increase of +9 to AC (Second Wind + Earthstrength class feature = +7, Total defense increases this by 2 more for a total of +9; Second Wind + Total Defense = +4 to other defenses).
That's a total of 21 points of defense increase if the record would be totaled up, or simply +9 increase to AC if not.
We could also take it simply for highest defense # for a given level. That round, Crag had AC 29.
Has anyone been able to beat that?
