Hybrid build?

[Rosebourne]

I was wondering if going combat/alchemy would make my signs crap or would they still be useful by charging them up using potions and such from alchemy? I was sorta hoping to make a hybrid that could be decent at everything.

Signs are always useful no matter what you use your ability points on, combat/alchemy is a really good way to go about it and there are plenty of potions that will help you maximize the signs effects

What are some missable sidequest?

[NekoDave]

It's up to you but if you be a jack of all trades you will miss out on the most powerful abilities which require lots of points. I think you'll be the most powerful if you specialise in 1 or 2 trees. But do whatever you feel is fun.

Explore all the ? areas and check out all the notice boards and you shouldn't miss the side quests. Also check merchants for any treasure maps which open Witcher gear hunt quests.
