ok, a few questions here...
about size
1) when a beastmorph alch chooses abilities from alter self or beast shape, can he choose to alter his size? (would this be counted as an ability of the beast shape?)
2) if the beastmorph is a small creature already, and size is considered an ability, would that mean the beastmorph could move to tiny (if small was the animal size) or diminuitive (if the animal was tiny?)
3) when a beastmorph chooses and animal (such as a merman) to mimic, and chooses swim as an ability, does that mean the character can now breathe underwater? or if he chooses a creature with fly, does that mean he can fly at a low oxygen atmosphere if the animal can do so?
