Traits and Actions

Magic Resistance

Trait
Advantage Custom
The Moonveil has Advantage on saving throws against spells and other magical effects.

Spell Slot Drainage

Trait
Spell Slots Rule
When the Moonveil hits a creature with an attack, if that creature has any spell slots remaining, the Moonveil can choose to expend one of the target's lowest-level spell slots. The target takes no damage from this choice, but the slot is lost. If the target has no slots, nothing happens.

Arcane Empowerment

Trait
Long Rest Rule
For each spell slot drained in the last hour, the Moonveil gains +1 to its Armor Class and +1 to its attack rolls, up to a maximum of +3. This bonus resets after a long rest.

Invisibility to Detection

Trait
Detect Magic Spell
The Moonveil does not register as magical to Detect Magic or similar divination effects. It appears mundane unless observed directly.

Unarmed Strike

Action
Concentration Rule
Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (2d6+3) slashing damage plus 7 (2d6) necrotic damage. If the target is concentrating on a spell, the concentration ends immediately without a save.
