What do I do with advanced capsules?
And if you run out, they can be purchased at the NPC shop. You can also exchange early lettered advanced capsules for later lettered advanced capsules at the exchange shops. (IE: a for b, b for c, etc.)
@coldreactive too add to this, you can also purchase 50 of each capsule type a week in the Alliance Shop. It only costs 500 Alliance Points and is useful if you want to +50 risk inmediately.
