Does -3 double if two people are fighting?

Say, for instance, Brooke is fighting a Level 16 Fenris. Fenris is -3 against Clerics. Brooke is fighting it and ask for help from another player. I offer help and she accepts. I am also a Cleric. Is it now -6 to Fenris or still -3?

Does this also happen for monsters that gain a bonus from certain classes or races? Like Level 6 Cerberus who gets +3 against Clerics. If Brooke and I were fighting against him and we are both Clerics, does Cerberus gain +6 and have and attack power of 12? Do all monsters with similar effects gain and lose attack power for each Munchkin that falls into the category?

No. Those kind of bonuses and penalties do not stack. The rules for multiple players in a combat do address this issue:

The parenthetical statement implies, strongly, that once a penalty or bonus is applied, it does not get applied again if both players in the combat would get potentially get the bonus.
