There’s an interesting synergy with the Old Hunting Rifle here. Normally, fighters don’t plan on taking too many shots that have a chance to miss due to the value of ammo tokens on weapons, making the ability to reroll base tokens relatively redundant short of canceling the worst non auto fail token.
With the Old Hunting Rifle though, firing it normally can be quite a crapshoot due to skulls jamming the weapon and screwing you out of a shot at the worst possible time. The ability to reroll said skulls is a godsend in this situation, making it a lot more reliable.
As of right now, there’s two classes that can have level 2 guardian access that also have access to the Rifle: William Yorick and Lola Hayes. Lola is effectively out due to not being able to use the rifle and trigger the reaction on custom modifications together, which leaves our favorite gravedigger. Said gravedigger is normally somewhat at a loss for high damage firearms, but there’s a second synergy available to him: Quicksilver bullets and Will to Survive.
The 3 or more condition on Quicksilver Bullets is usually a bit of an ask. But what if, say, you had a turn in which you didn’t need to pull any tokens? Preload the rifle with some Extra Ammunition, throw a Police Badge at the nearest boss enemy, and you’ll be able to dish out 20 health worth of damage in a single turn, and that’s discounting recursion shenanigans with the Badge.
The biggest downside to this is that Yorick is a bit short on reloading events, and as custom modifications is an event, it doesn’t mesh well with his usual play style of plucking a freshly loaded gun off the nearest warm corpse; apparently servants of the mythos only buy mass produced gear. It’s still worth considering to load up for a big boss kill though.
