What the issue? Can't reserve all? Probably need more increased Mana reservation efficiency of skills mods on gear.

Charisma annoint on amulet can help.

Ashes of the stars amulet can help but its pricey.

Replica Dragonfang's flight bit cheaper and would help aswell. Make sure its Righteous Fire Gems

Body Armor can get the Mana Reservation efficiency mod also something like this.

Enlighten gem also gives more room for reservation get level 4 if you can afford it.
