General

if you look carefully, none of his equips have potential on them, except for the tempest ring (epic), violet snowshoes (rare), and aegis (rare).

Mines twice yours with no NX used and no RA set, level 18x.

How much with buffs?

My 175 paladin have a similar range unbuffed, but with 5 charges and blast buff it jumps to almost twice (Around 80-90k)

I'm not sure that it's all that great.. do you have link skills and stuff? My demon slayer is 161 and has pretty minimal funding and I have like 3/4's of your range
