Update: It still costs AP swapping items from main-hand and off-hand.
Ok but, when you put a sword in your main hand does it work in close melee range?
I believe it still costs AP, but I'll specifically test that some time today hopefully.
I tested this in the past. With sword in main it's standard melee attack. With wand in main it's standard magic attack. It costs 1 ap to swap their position,then 2 more to execute a basic attack.
That is so ass-backwards. Should be regular 2AP to attack, if not in range to melee, melee attack misses.
