Not in isolation, no. What do you want to use him for?

For dungeons basically

I haven't pulled him yet, but when I do my main focus will be to use him as a debuffer, so prioritize accuracy to land those freezes - aim for around 250+. As my gear improves, slowly develop his damage on top of that. You'll also want to focus on speed boots for your champions, except for nukers and slow HP tanks.
