Long time heroes of might and magic player here but decided to give Kings bounty a shot. This is the first version ive ever played so I was wondering if any long time players can give me pointers on the must have skills/magic or anything else a beginner might miss.

I already started a game on medium and beat the spider boss but I am planning to start again on hard or impossible so any pro-tips would be appreciated.

Fun game btw..soundtrack is sick!
