I find this game very frustrating at times as there seems to often be missing information.
For example, I unlocked the necromancer skill, which says I raise skeletons to fight for me. What does that mean? There's no skeletons when I go into combat. There's no attacks relating to it. I haven't seen any options for it.
Same with burning a certain tree upgrading something called "oaken shield". What does that do? I don't have an inventory, I don't have a skill called that?
I like exploring and mysteries but if I'm left wondering if a skill is bugged or a message was shown incorrectly, that shifts it from being mysterious to poorly designed UI.
