Arcanist's 'Mana Call' spell is not in the spellbook

[wary vault]

It also seems you cannot change the spell's keybind without grabbing it from the spellbook so Mana Call is stuck as spell number 2 at all times

See patch notes, manacall is no longer the Arcanists responsibility - duelists are taking on the role of group mana management

They'll keep you topped up
