The wild warg chieftain model is on a rock. for the purposes of los does his increased height allow really give him the extra los, or would you count it as just a fancy model and count los as if he was in a regular warg position?

this occurred to me because i want to use one soon, but i was thinking of how to protect him from missile fire as he annoyingly stands above all the other wargs....

All models are assumed to be wysiwyg (what you see is what you get). Otherwise the game would devolve into a nitpicking nightmare.

Yup, you would measure from the actual model. This might seem unfair but it shoots both ways. Being high up can mean you also get further LoS for shooting, spells etc. but I'm sure there's some kinda ban on this in tournies. Your opponent will still have to take in the way shots foryour chiefy but if you want a midget chieftan, just convert a normal warg.
