Like Lexi said, to beat the game you don't really need a guide. But for the special stuff there's no way to do it without it, I reckon. I finished the game but I haven't got any of the special weapons except for the ones in plain view at treasure chests. I managed to get all the way to the Behemoth King hunt without a guide but I'm stuck in it now.

I figured out the equip the dawn shard on Mirian fine, but got confused with the statues. I was making them face the sword on a 2D view when they should face the sword in "real life" , i.e. on a 3D view of the temple (which meant they should all face the center in 2D). Draklor Labs, Giruvegan and other puzzles were not that hard. The hard puzzles are in the side missions!
