Hello! Sorry for my English but I'm not a native speaker.
I've got ho SR in easy situations work, but I have some doubts when I think about actual combats and multiple actions outside of melee.
Most problems revolve around movement. First of all, it's quite confusing that they dedicated phase 2 to movement, but from the examples it looks like you can (or must only?) actually move in phase 3.
Then, not-engaged pc:
1) does he add dex sr twice if he both casts a spirit magic spell and shoot an arrow? Does it all happen at once at the total sr? Or does he first casts at x sr, and then shoots. At x+y sr?
2) if he moves between those two actions, does sr modifier due to movement adds to the second action only?
3) if he moves before casting, does movement sr modifier add to the casting sr? (consequently, also the shooting will happen later)
4) if context changes a lot after phase 1 declaration of intent due to surprise (eg an hidden creature gets out of nowhere), are pcs allowed to change their actions entirely or not?
5) does gm declares before the pcs do, or the contrary?
6) combination of actions can't surpass 12 sr, but spells can be cast in 37 sr, so at sr 1 of the fourth melee round, as per rulebook. If a pc shoots two arrows and (let's say) is at sr 11 with his second arrow, can he start casting a spirit spell that would require dex sr+3 sr for magic points and cast it in the next melee round at sr 2?
7) since all rune spells if not boosted get casted at sr 1 (i assume dex sr does not apply here?), a pc will never be able to do anything else BEFORE casting a rune spell? Or only move + rune spell (casting it at movement sr+1) Or that's not what they intended, and it simply means that rune spells "cost" 1 sr?
