Leeches (CL 2)
Saga Edition Core Rulebook, page 3 (table of contents).
Tiny parasites attach to your skin and suck your fluids for nourishment.
Type: Natural
Trigger: A creature begins its turn in an area occupied by leeches.
Attack: +4 vs. Reflex Defense
Damage/Effect: The target moves −1 persistent step on the condition track.
Recurrence: Each round at the start of the target’s turn, until removed.
Skill:
Treat Injury (DC 19): The character safely removes the leeches.
Special: Leeches ignore the effects of a creature’s armor, unless the armor is natural or airtight.
At some point, creatures traveling through a swamp must trudge through water. When they do, they might encounter leeches. Leeches have a way of slipping past the best defenses and latching onto the skin under a creature’s armor or clothing. Not only do these parasites cause damage to the creatures they attack, they can cause a group to be hesitant to enter other bodies of water, giving opponents a chance to strike.
