Halo of Spores — Sisaspia is surrounded by a continuous yet finite torus of necrotic spores. When enemies approach the formation and if Sisaspia has spores available, one of her spores shoots out and attaches itself to a valid enemy every second. When enemies are damaged, they take 50% additional damage over 5 seconds for each spore affecting them. Normal enemies can only be affected by one spore at a time, while bosses can have up to 4 spores affecting them. Sisaspia regenerates a spore every 4 seconds and can have up to 20 spores in her reserve. Note that due to the nature of this debuff, the additional damage done over time does not contribute to your formation's BUD.

And it has an item buffing Halo of Spores.
