I'm working on a custom race. They have, in my mind, the ability to assume a specific humanoid form (elf, dwarf, human) etc... This form is determined at birth and doesn't change, and they can assume it with no time limits per day. It's a large race though, and the lesser change shape says it has to be the same size. I was wondering if adding +1 to the point cost might seem reasonable to make the change to it being the proper size for the race chosen.
The second form they can take is that of an animal. Again, only one shape, determined at birth (character creation). Any advice on the cost for this ability?
