After receiving a wound, they are able to empower their next successful attack, causing it to do more damage than it normally would (for revenge)
They are able to empower a wounded ally with the fervor to achieve revenge upon the one who wounded them; this effect greatly increases the strength and speed of the ally when they fight the one who wounded them until revenge is achieved.
If someone is wronged, a revenge nymph can aid that person in getting revenge on whom ever wronged them
They have a telepathic/empathetic connection with nature and other nymphs
As they are nymphs they do not age, remaining eternally young.
They are quick to want revenge when they are wronged in any way
