Expected result:
You can move very slowly and roll dodge
Actual result:
You are no longer able to move and cannot roll dodge
When casting the Immovable skill with 5 heavy armour pieces and 2 medium pieces:
Expected result:
You can move very slowly and roll dodge
Actual result:
You are no longer able to move and cannot roll dodge
When casting the Immovable skill with 5 heavy armour pieces, 1 light piece, and 1 medium piece:

When casting the Immovable skill with 7 heavy armour pieces:

I have tested this with and without the new Bracing Anchor red CP and the result is the same.
This has been tested on a Nord Sorc, Redguard Dragonknight, Argonian Nightblade and the results were all the same.
