Once you are at High Rank in the game. Buy Attack Charm and Defense Charm from the supplies vendor. As long as you carry them in your pack, they give you attack/defense bonuses. Once you've slain the Bazelgeuse, you can buy a secondary set of charms, and combine them with Bazelgeuse drops. These second set of charms stack with the first set.

You'll have to do this in game to improve multiplayer with people in the group.
