The Vorago Jr pet is a popular utility pet. It gives a 15% drop rate bonus and restores prayer points based on the player's damage output. This makes it very useful at bosses and raids which drain your prayer, such as the Necromancer boss and the Diablo raid.
Vorago Jr is obtainable from the DreamScape Web Store for $300, or from Pet Mystery Boxes. Also can obtain the vorago pet from the new Donator ticket store at ::shops (currently costs 175 tickets)
