Wolf
From Portals of Phereon Wiki
Overview
Combat Creatures commonly seen in forested environments.
Combat
A decent combination of Speed and Strength, with attacks that inflict Bleeding. They are formidable early on but middling Stat Growths makes them poor late game units.
However, since you can acquire them very early and easily, you could put in the time to develop them. Strength Level Types are comparatively rare, and wolves are one of the easiest you can acquire. Alternatively, if you can get Catalyst on a wolf, you could fuse that to make another unit a Strength Level Type.
Overworld
Default wolves have no special use on the Overworld.
Breeding
Moneymaking
They can be sold for 100 gold at Medium size and for 300 gold at Enormous size. Every level above 1 additionally increases their price by 5%.
