Weapon - orb

[Tleno]

I need a little help... I am creating a map and... Well, there are weapons that are based on orbs, and I want to make so if melee Hero gets item, that item changes its attack range, so it would be, that Hero is not melee unit, but ranged. And if he drops item, he gets his normal attack again... And how to make that if Hero gets helmet or something like that, and he already has one, he would drop it, so he could have only 1.

Use enable attack 2 in the orb ability.
