Mana Points (or MP) are a resource required to cast various spell and abilities in Fell Seal: Arbiter's Mark
Gaining MP[]
Unlike many RPGs, characters start with 0 MP at the beginning of battle, which is replenished over time. At the beginning of each character's turn, they will gain 10 MP, up to their maximum MP.
In addition to naturally gaining MP each turn, there are several abilities and effects that can grant additional MP.
| Name | Source | Notes |
|---|---|---|
| Physie | Vessel | Restores 1.3x (MND) HP in a small area around the caster. Also restores 5 MP. |
| Mana Rock | Consumable | Recovers 10 MP (20 when upgraded) to a single character. |
| Forest Flute | Niwot | Restores 0.5x (MND) HP to the target. 25% of the restored HP is also restored as MP. |
| Energizer | Gadgeteer | Recovers 20 MP to a single character. |
| Mana Expert | Gadgeteer | Start each battle with 15 MP instead of 0. |
| Absorb MP | Gadgeteer, Therva | When character is targeted by an offensive Ability that has an MP cost, they gain the same amount of MP that was used. Only triggers if the offensive Ability would do damage to the target. |
| Mana Font | Mender, Daodrenner | Character recovers 1 MP with each step taken. |
| Arcane Engine | Cadaver | 10% of HP restored beyond maximum is converted into MP |
| Leech Mana | Warmage | Character's Regular Attack converts 10% of the damage dealt into MP (maximum 15 MP). |
| Versatile | Fellblade, Niwot | Allows the character's Skills and Spells to inflict Critical Hits, and when the character lands a Critical Hit, they regain 5% of their maximum MP (minimum 5 MP, maximum 15 MP). |
While it doesn't directly provide MP, the Economy passive ability from Sorcerer and Archafflictor is notable for reducing the mana cost of all active abilities by 1/3, which can greatly assist with using abilities with a high MP cost.
Draining MP[]
A few abilities are also capable of draining a target's MP, and restoring it to the caster. These abilities cannot drain more MP than the target has, so avoid using these abilities on targets with little to no MP left.
| Name | Source | Notes |
|---|---|---|
| Siphon | Templar | Deals 0.75x Magical (ATK+MND) damage to the target and does 0.33x of that amount as MP damage that is absorbed. (The MP damage is maxed at 25.) |
| Soul Suck | Vampire, Cadaver | Deals 0.3x Magical (MND) damage to the target's MP and absorbs the damage dealt as MP. Deals 0.3x more damage if the target is inflicted with  Bleed.
|
| Drain Soul | Marked | Deals 0.45x Magical (MND) damage to the target's MP and absorbs the damage dealt as MP. |
| Ravenous Soul | Mummified | Deals 0.75x Magical (MND) damage to the target's HP and MP and absorbs it. |
The Mana Burn passive ability from Malcubus is also capable to dealing damage to an opponent's MP, but unlike the above abilities, it will not restore any MP to the caster.
