I don't know, it seems like the abilities work the same for everyone, but they consume a lot of mana, so I don't upgrade healing anymore. Lightning is very cheap, frenzy is cheap, and so on.
Ugh... some jerk attacked me on Kashik... We met on a small square, and the only path to retreat was blocked by very unfriendly creatures... I replayed it at least 5 times, I got tired of running away from him. When I almost defeated him (I use the following strategy: I run around - my strength recovers - if I have time, I use a potion and cast a shield - I cast lightning - I throw a grenade - he runs up - I exit the battle - see what happens first), unfriendly creatures appeared on the square, and I had almost no health left. In the end, I ran away from them, recovered, and easily defeated everything with lightning.
Damn, Drakoshka, I mention you with kind words every time I write a post for telling me about insert
Where do we end up when we save the world?
