SPECIAL TRAITS

• Blood Sense. The giant flea can pinpoint, by scent, the location of creatures that have blood within 60 feet of it.
• Keen Smell. The swarm has advantage on Wisdom (Perception) checks that rely on smell.
• Ravenous. When a creature that doesn’t have all of its hp starts its turn in the swarm’s space, that creature must succeed on a DC 12 Dexterity saving throw or lose 5 (2d4) hp from blood loss.
• Standing Leap. The swarm’s long jump is up to 30 feet and its high jump is up to 15 feet, with or without a running start.
• Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny flea. The swarm can’t regain hp or gain temporary hp.

ACTIONS

• Bite. Melee Weapon Attack: +4 to hit, reach 0 ft., one creature in the swarm’s space. Hit: 14 (4d6) piercing damage, or 7 (2d6) piercing damage if the swarm has half its hp or fewer.
