I haven't worked much recently, but quick update on a few things I'll add.

1. Mutated Gavla (moreso than set form)

2. A bit of change from the book, instead of all five Makuta heading down at once the three canister ones will and then Mutran will betray Icarax and they'll fight.

3. One of the 8 Makuta will die.

4. Ignika will use some powers not used in story, like the fact that its body is seaweed and other powers natural to the mask.

And that's it for now I guess.
