The Beasts of Prodigum event applies to the standard Torghast levels, which are currently useful for Soul Ash.
Horgul, for instance, makes for a decent tank in a pinch, while Nal’tari is a support beast that makes the player much more of a threat.
These are special powers that give the player access to a beast.
A new event changes Torghast up, providing players with a big burly beast ally to help them clear their way through the Jailer’s tower.
For the rest of the Torghast run, the player will continue to get Beasts of Prodigum anima powers.
