how do you get past valravn
You need about 65 power and 15 skill, which you likely already have.
When he attacks you with his powered up sword, stay away, then, go all in, and finally, choose NOT to evolve.
A lot of people take the horn and max their stats to beat the fight, but realistically, it's not that stat-intensive.
I'd much rather wait and see what the eye does. Hopefully in the next update.
