Having just finished a sniper game where I had a single +3 shuriken and a single +2 kunai, being able to upgrade a stack would certainly have been a nice change.

If you’re the battlemage, your staff gets an additional melee characteristic based on what wand is imbued in it. For some wands (fireblast, lightning, frost) this is basically identical to an enchantment. But you’re also allowed to use a stone or scroll of enchantment to enchant your staff just like any other melee weapon. So you could in theory have a staff that’s essentially both shocking and blazing, for instance.

I’ve often thought it would be cool if you could harvest darts from dart/poison dart traps, but maybe that would make the crossbow too powerful

How will this interact with the sniper’s Shared Enchantments ability? Will it be like how the battlemage’s staff can essentially have two enchantments?

Had a run a little while ago where I got a projecting whip and a ring of arcana, but +14 is sheer madness. Incredible.
