does the caster (or druid)get the beasts stats or does he just improve his own stats
im just wondering cuz im planing on running a wizer with the trans school
You improve your own stats. Playing a shapechanging wizard or druid and planning on using the shapechange spells in order to deal melee damage isn't a very good option under the Pathfinder Beta rules.
I think Beast Shape 1 to be kind of "underpowered"... The way it works, it's not worht even transcribing it.
One of the possible uses of BSh 1 is taking an aquatic form, which is, quite often, handy. But Alter Self (which is a 2nd level spell) can do the same, and still allowing spellcasting, as you assume a humanoid shape.
My suggestion is to increase the ability bonus granted by this spell chain (Beast Shape I, II, and III) by +2, as most of Medium-sized animals are quite strong, and small animals are quite nimble.
