Potion that restores 200 mana gradually over two minutes rather than refilling spell points instantly.
Thirty Good Mana Refills come off Bravvo's corpse, a type Carl had not seen before. Where a regular mana potion completely refills spell points the instant it is drunk, these add 200 mana points spread across two minutes.
Carl explains to Princess Donut why the slow drip beats an instant refill in certain situations — a full pool cannot absorb an instant potion, but a steady trickle keeps a caster spending through a long fight. He keeps two for himself and gives her the rest, along with the thirty Good Health Potions from the same haul.
A potion bottle, thirty of which filled part of the hunter's limited slot inventory.
Slow-restore mana consumable that suits sustained casting better than an instant refill.
