A couple of sessions ago, I improvised a magical item as a reward. It’s much like the ‘glaive’ from the movie Krull a huge shuriken-boomerang thing that can slice through walls. Then I forgot about it and didn’t write any rules, tags, or special moves for it. But now the Fighter tells me he wants to take Blacksmith to merge the glaive’s powers into his gigantic sword.
So here’s what I’m thinking: when you attack by throwing your sword, it always comes back(ø). If you trigger Volley with it, on a 7-9 you can choose The sword causes a dangerous amount of collateral damage as a side effect.
(ø) Note that I’m not saying when the sword comes back. I’m expecting some Thor jokes next time 😉
