An Eclectic Collection of Fun and Effective Builds 3

[Wraith]

Not really sure Grung is a good race choice, though. A DC 12 Con save is quite easy to make for many baddies, which entirely negates the extra damage.

Undoubtedly something like Halfling or Fairy would be better simply because they have similar stats but even better movement and magic options. Kobold would also be interesting for on-demand Advantage to guarantee Sneak Attack damage, too.

Just for flavour and the fun of being a psychotic frog-man, I think it's good enough for levels 1-5 when the extra damage really makes a difference, and after that when Horizon Walker turns it into Force damage, it's a nice bonus when it does go off. If nothing else, it's enough to one-shot several minions per turn, even if the BBEG ignores it most of the time. That's still a useful role.
