Kangaxx missing body (arm and leg)

Hey everybody,

I messed my Kangaxx quest up. Can’t get the door open to reach the last two Items I need to summon him (I somehow fu+++ the cult of unseen quest up)
The door in the sewer is still locked somehow - no Gaal and whatsoever - quest finish thou. (I think I killed the cult)


So, can anybody help me? Any idea how to get through the door to get the two missing body parts? I tried pushin with summons my char over, no success. (Bear, ogre,...)

Playing on IOS (iPad)

Is there anybody who can help me? Been so stocked about killing Kangaxx.

Thanks in advance
