Claymore after gem mod:
(For max damage)
Attack 13-100 Critical 17%
Balance 20% Durability 8
194 / 108,700G
Attack 18-100 Critical 30%
Balance 23% Durability 8
222 / 133,700G
Claymore is the highest crit weapon to obtain 100+ damage. It's trading 4 damage for 12 crit in comparison to the Dustin.
A Claymore can get 88max, 45crit with gem upgrade.
A Dragon Blade only gets 75max, 38crit.
Dustin Sword sits at 76max, 43crit.
Therefore I would pick Claymore for either max or crit. Dustin for pure max, and Dragon Blade only for balance and easy repairs.
