For Eidolons, only the main slot gets the passive activated.

For weapons, only Soul weapons matter in the main slot. Everything - main weapon and not - should be the same element. That's not possible for a new player, but that's what you should be aiming for. Since off-element weapon skills don't apply to the team at all, only their base stats.
