Capping with Smite

More boss damage.
With a 2m~2m range, you would need ~240% Total/Boss to hit cap when you include the Adventurer Hyper Buff, and then some more to overcome defense reductions. -20% if you take the Reinforce Hyper Skill, but I would advise against this.

I believe he meant the theoretical range beyond 2m~2m that he'd need, since the range cap seems to be entirely visual and not a hard cap.
