Astrovarg (5e Creature)
From D&D Wiki
Medium beast, unaligned
Pack Tactics. The astrovarg has advantage on attack rolls against a creature if at least one of the astrovarg's allies is within 5 feet of the creature and the ally isn't incapacitated.
Charge. If the astrovarg moves at least 20 feet straight toward a target and then hits it with a ram attack on the same turn, the target takes an extra 5 (2d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone.
Astroleap (1/Day). With a 10 foot running start, the astrovarg can make an astroleap. If the astrovarg is on a spacejammer vessel, asteroid or tiny planet, this is a 120-foot long jump that takes it out of that body's gravitational field. If the astrovarg is on a planet, this is a long jump up to 60 feet.
Ram. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) bludgeoning damage.
Astrovargs are wolves that have adapted to live in space. They live in packs on asteroids and tiny planets, where they hunt anything edible that resides there, migrating to other astronomical objects or spelljamming vessels when overpopulated.
