Need clarifications for some rules...

Hi brothers.

Yesterday I played Mordrak for the first time, and I have a question. It is wrote that when he lost A wound, you have to cast a die, then blablabla... But if he lost 2, or 3 wounds during a single phase, does it mean that I would roll 2 or 3 dices ? During the game, he lose 3 wounds during a shouting phase, so did I have to run 1D3 or 3D3 ?

The other one is concerning Stormraven. In the codex, it is described as "fast skimmer", but in the FAQ there a point about "zooming stormraven" or "hovering stormraven". I have not read something, in the FAQ, that it should be considered as a flyer. So I refer to rulebook page 81 and I consider my stormraven as a flyer having the "Hover type" rule ?

For the second question, there's an appendix in the back of the main rulebook which updates all the model types. It also does things like make a dreadknight a character so it can use precision strikes.

Thank you, I did not think to look in this appendix.

Somebody can help for the first part ? I have not been able to have a clean answer on Dakkadakka
