Mana Overflow Methods

I'm working on a bit of a project, and I wanted to know of whatever mana overflow methods are currently possible in Wynncraft. So far I'm aware of Arcane Overflow, and also the method of swapping off a weapon with +intel while you have max mana. Are there other methods of doing this? For example, does Invigorating Wave work? Weightless?

 

I don't think the weapon swapping method is intended...
