Elementalist -- how to equip Arcane?
Arcane is a specialization, but it’s not an attunement. It’s a specialization that’s meant to affect all four elemental attunements.
Elementalists can use Fire, Water, Air and Earth Attunements only, swapping between them with F1 through F4, regardless of the specializations they equip.
OMG — that info has changed my world=) TY so much for the quick and clear answer!
