What is your favorite Skill so far in terms of Design, Specialization and interaction with other skills?
I nominate Summon Wolf. Specialization really makes Wolves strong, really strong. The Bleeding route with Beastmaster is excellent and the Lightning route with Shaman is even more amazing IMO. The specialization allows you to build tougher, or faster or wolves that Leap (although the Leap skill is less important when Wolves are running at full speed).
I even tried the Rapid Summoning route which is kind of interesting.
Overall, Wolves are very strong and even more so with The Fang amulet. You can’t build a bad wolf. lol
