Group/ally fighting bonuses (not minion group)

By Josep Maria, in Star Wars: Edge of the Empire RPG

Hi again!

I begin to understand minon group rules, with a few doubts about limits on bonuses stack, in my opinion the max is 5 proficency dices but its just a personal valoration.

But lets say that two allies fight together. I know that there is the Boost bonus, but one of them refuses to attack. I understand that part but the target gets some kind of penalization because its fighting againts 2 or more PC's?

There is some kind of flank or multiobjective benefit? Or two PC's with 4 at skills must always sacrifice one attack to add one Boost?

Thanks again!

They can spend their advantage to give each other boost dice.

I forgot to say that its enought a Boost (or a few) againt a full dice pool from another attacker?
