Parasites are enemies impregnated in the player by Phosani's Nightmare while fighting her. After ~18 ticks (10.8s), the parasite grows and bursts out of the player, dealing 5–10 damage. It will always spawn one tile away in the direction the player character is facing. Drinking a dose of Sanfew serum or Relicym's balm after being impregnated will weaken the parasite; if the parasite is not weakened, it deals significantly more damage (~90 damage) when bursting out which is added to its health, it spawns with higher stats, and the player loses the ability to inflict the maximum hit on the parasite if using a crush weapon.

If clicking the Player Hitpoints Orb to weaken parasites, it will prioritise Relicym's Balm over Sanfew Serums within the player inventory.

If Phosani's Nightmare's shield is partly damaged, they target her to restore her shield. In the situation where one or more totems are partially charged, they target the least charged totem to discharge it until the totem is completely discharged. The heal amount is ~51 to 100 per attack. If there are no suitable targets to heal, parasites attack the player. They alternate Ranged and Magic attacks starting with a Ranged attack. Using protection prayers will fully negate their hits.
