Ingrid the Warmaiden:
Istvan & GM, what about a "Colichemarde of Dancing Blades", a rapier that gains a charge (up to three total) each time you land a blow. The sword gains Piercing X, where X is the number of charges. The charges can also be spent like Hold from a Defend move, to either lock down an opponent or Riposte or deflect their attacks.
Would that be a good goal for his artifact?
It'd be great... except I already chose the Quicksilver technique, which can grant me piercing... So I'd prefer something I can't already do, nor learn to do...
But the charging-up-and-then-using-the-charges bit is great... Let's keep that, but have them do something else... Mmmm... But what...?
