Should I make a Jizai?


If you wanna keep hunting I'd do it for the %'s more than the hit, since Jizai is already pretty accurate on its own. My HUnl doesn't have much issue hitting things even in subdes. You're playing HUcast iirc mostly so you'll have freeze traps regardless.
Neither of the halves are incredibly hard to get. If I were you, I'd make one for now with crappy percents (if you're actually gonna use it), then later hunt a half with hit.
