The wraith adaption needs to be Toilet wraith.
Her back has Toilet lid instead of spikes, her arms are flushers and her body looks like a sewer.
Flushing abduct- Wraith has a shorter rang in abduct but grabs the hunter and swirls back and pulls any other hunter in its radius to her spot in a toilet flushing manner leaving a trail of poison clouds.
Clogged blast- Wraith warps forward a short distance but the explosion created leaves sewage puddle or bubble dealing DOT.
Toxic decoy- weaker and does less damage it applies DOT, it also explodes upon death dealing big damage.
Toxic nova- like supernova but slower, but it applies a DOT effect and slow effect on hunters.
