So the BRB explains that characters who roll 6's to hit may then allocate wounds caused by those attacks - this is different to normal wound allocation. However, nothing explains *how* to allocate. The wording seems to imply you roll to wound first (which is fine given the rules for mixed toughness) but how are the wounds applied? Do I allocate all at once? Do I allocate and roll saves one at a time?
This has the potential to be completely nerfed - for example, spending 3 wounds to kill a special weapon trooper, he fails his first save, and all subsequent wounds are wasted.
Or it has the potential to be OP- I cause 6 precision wounds and make you roll saves off until I kill your meltagunner, then missile launcher, then unit champ and designate any additional wounds at an Independent Character in the unit for lols.
