Wyrmholes spawn during the fight with Astellarn. Astellarn will choose a player to have the unstabilised wyrmhole spawn on. Standing on it will cause increasing typeless damage until stepped off. After a neutron star has been brought on it, it will turn into a stabilised wyrmhole and the player will have to stand on it in order to do damage to Astellarn.
