Sigil: City of Doors

Hello, can we get the stats of the advanced dragon shapes?

and also, does practised spellcaster counts toward its requirement?(27 CL) or only actual druid levels counts towards it?

It does if you have the required levels (27 character levels). The stats change depending on the color , i don't have a list currently however its a minor stat increase, spell resistance increase and most importantly the multi-attack feat.
