There are also other cool things that can be done with 1s on gear besides breaking.

Ammo, collateral damage, injuring the mechanic, triggering a complication like a radiation leak or low fuel. Basically treat 1s like PBTA 7-9s with the harshness of the “but” tied to the number of 1s.

I would do all the dice like this with gear vs ability dice differing only in the flavor of the “but”.

In MZ0 Skill dice are free of complicating 1s, bit that’s an easy switch to flip. Maybe 1s on skill dice represent how much you need to than the icons for their blessings, representing a certain amount of prayer / sacrifice / devotion that must be met. If not met, prayers stop working…or something like that.
