Bioluminescent. A mana wyrm is natural luminescent, and sheds dim light out to 5 feet. The more mana the mana wyrm has stored, the brighter it lights (up to 1 foot per mana point, minimum 5 feet as described above).
Magic Devourer. The mana wyrm can, when using its spell siphon ability, drain a spell slot from a target. It does not gain spell slots normally, and must feed on sources of spell slots.
Magic Weapons. The mana wyrm ancient’s weapon attacks are magical.
Innate Spellcasting. The mana wyrm ancient is a 6th level spellcaster. The ancient mana wyrm's spellcasting ability is Intelligence (spell save DC 15, +7 to spell attacks). It can innately cast the following spells, requiring only verbal components and available spell slots:
Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 8 (1d6 +5) piercing damage.
Mana Siphon. Melee Weapon Attack: +7 to hit, reach 5 ft., one target that has magic. Hit: 5 (2d4) arcane damage, and the mana wyrm drains the magic essence from the target. Each successful siphon adds a 3rd level spell slot that can be used to cast 3rd level spells or lower.
Mana wyrms are simple, glowing critters that float around feeding off of stray pockets of arcane energy, clustering around places of power such as mana fountains. They can be familiars of spellcasters, but demand more upkeep magically-speaking (in terms of feeding them mana). Mana wyrms are usually translucently blue in color, but their color can change depending on the mana they drain.
