Exp Woes..

[worldofneil]

There's a FC action that gives you extra EXP from monsters. It's like 10-20% but I can't remember exactly

Yep, Heat of Battle which gives extra exp as you stated. Depends which one the FC has active, but:

Heat of Battle 1: 5% (purchase with company points or crafted then charged in an aetherial wheel)
Heat of Battle 2: 10% (purchase with company points or crafted in a workshop then charged in an aetherial wheel)
Heat of Battle 3: 15% (only crafted in a workshop and then charged in an aetherial wheel)
