after u get burning man, the next morph u get is the golem. his "rockthrow" ability is
what u need to knock down the "massive doors".

yep, It looks like you get the mouse form in raw fade, then the burning man form in
"Burning Man" (by going through the second mouse-hole), the golem form in the "Mages
Asunder" missions (from the cursed dreamer), and that allows you to break down several
doors to complete other missions. Then you get the spirit form in Darkspawn invasion.

One more thing lads in order to get the last boss use the Spirit Form to go through
"spirit doors". PS: I hated being the Fade very annoying and confusing have fun and good
luck.

I wish i would've done that quest instead of this one i'm having troubles with. It's the
one where you have to go inside the Castle to get some girl, but i keep dying in the small
room with five or six undeads inside... It's very hard with all of them attacking at
once.They're easier by twos or threes.
