For now when a wand it's on offhand it will cast with right click even if the cast key it's left_click. I would like to request a option to disable wand cast, attribute stack when on off_hand slot plus a option to block the use of the off_hand slot when the wand is equiped.

/mconfig configure allow_offhand_casting false will turn off offhand casting.
I think it may also prevent attribute stacking in offhand, it should basically prevent wands from appearing active in the offhand at all, but let me know if that is not the case.

Thanks Nathan! I remember you mentioning somewhere that, but couldn't find the message at the discord.
The way I work with the wand damage it's assing an value attribute to it, that's why the atrribute stack part. But do you have any suggestion how can I "import" the value of the attribute of the wand when it's on offhand? So I import atrribute "sword1" from the main sword only and "sword2" from the offhand sword only.
