Dual wield

So, question of the day. When wielding a sun sceptre (4 str) and dual wielding an icicle (4 str) it is fine. However, if I want to wield a sun sceptre (4 str) and dual a sun sceptre (4 str), it is 'too heavy to be used as a secondary weapon'.

identify the two items. Generally, one would be heavier than the other, thus allowing dual wield to work. If they're the same weight, or the offhand weapon is heavier than the first hand, it won't.

However, BLMs are the exception in dual wielding same weight weapons.

Ahh, right, same weight. Bleh, guess time to go search for another that I can dual wield.
