Maybe this is 100% coincidental but
Every time I've turned this game off, left it off for 12+ hours, then started it back up: the first enemy I encounter has 3+ metal slimes with it. Has this happened to anyone else, or am I getting incredibly lucky? Erik's metalcutter boomerang ability is slaughtering these fools en masse, and I'm raising my character's levels 2-3 times every time I boot up the game, which has helped with not having to grind. Could just be me getting incredibly lucky though, but it's happened 4 times now in exactly the same way.
