The Mabinogi Wiki says that at 5 charges, it goes 6.5x the base damage.
Would that be the damage of one bolt (and then we charge it 5 times, but 6.5 meaning there's a 1.5 boost?) or is it a 6.5 boost for five bolts (meaning there's a 6.5 damage boost).
Do you get it? Ask for examples if needed.
EDIT: Didn't want to start a new thread, so. If anyone could answer these questions too:
1. When you change wands (is it just meditation or no?) meaning going from one wand to another, do you lose MP too?
2. Do certain wands give certain boosts to certain skills, or is it just what upgrades you want? (Fire giving a boost to firebolt, ice giving a boost to icebolt, etc.)
