I would like to use the spear as a base weapon for custom weapons like daggers, polearms, and some swords because of it's unique attack style and attack animation, but the blind spot of 2 blocks is a huge limiting factor. Is this hard coded or could it be controlled by a plugin?

As a side note, the right click ability is not desirable either for certain weapons. I currently use MMOItems to disable it but the interaction with a spear is visually undesirable I am assuming this is hard coded behavior as well and aside from disabling the right click interaction entirely, you cannot get around this, meaning no weapon with a spear as the base item will ever be able to use an off hand item like a shield.
