Angry vampyres are a possible result of using a dose of Guthix balance on a vampyre juvenile or vampyre juvinate. They become enraged, and attack you, but unlike normally, they can be harmed with any weapon, not just silver. They physically appear to be a larger version of the feral vampyres that inhabit Morytania, and they do in fact count for Vampyre slayer assignments.
- Previously the kind of vampyre you use a potion on affected the name of the Angry vampyre you got, so you could get angry juvinates from vampyre juvinates near Burgh De Rott.
- If a female vampyre juvenile is transformed into an angry vampyre, they lose all female characteristics.
