I'm not impressed on suggested skills for the second Skill-tree...

My suggestions is to add some Astral magic/Astral plane/etc which Astral Master could visit/look/interact with.

But it's a much bigger than just skill tree – it should be a whole additional layer for the game, with own creatures (spirits and so on), own quests, and much more cool new things.

Hey, Larian Guys, please tell me you have seen this my idea (even in case if you won't add it to the game – just to know your opinion about such things)
