Monterey Jack wants to go fast. Which means being away from the party tank. This weapon solves a lot of problems in an elegant way:
*You don’t need to play it until an enemy shows up.
*It doesn’t exhaust until want it to. Kill a one HP foe, then exhaust a boss. Or get it enchanted to do a two damage evade.
*You can use it on massive enemies or people engaged with others, with a low risk of damaging them.
It’s also extremely cheap for what it does, and can trigger any number of skill cards, like watch this or manual dexterity, which are harder to get from your seeker cards.
