Hey there, I'm new to this game and have a question regarding a thing explained rather vague in the rulebook IMO; Invulnerable saves.
Do they work as an additional armor save? Are they optionally used instead of armor saves? I can't wrap my head around it.
Could someone please explain?
take a space marine terminator , he has a 2+ armour save OR a 5+ invunarable save .
If you shot him with a bolt pistol he would use his armour save as a bolt pistol is only AP 5 and his armour save is better .
If you shot him with a AP1 melta which would ignore his armour save , then you would use his invunarable save .
