Do you know much about the blessings of Odin. I am getting close to getting a blessing and I think you can use them on several things or at least I hope so. You have to grind a bit to get to 100 blessings that is for sure.
So it will be interesting to see how they differentiate Dr. Strange from Loki, since they both use magic. Dr. Strange will have his shield of seraphim for defense, hoepfully and eye of agamotto attack, astral projection and stuff like that. He should be really fun to play.
