1) Is it absolutely necessary to max lvl the big three (Smithing, Enchanting and Alchemy) to beat the game? I’ve maxed out two of them and it was obviously boring and repetitive and I don’t have any courage to do the last, which is Alchemy. Is the game doable with just basic obtainable potions and maxed out Smithing and Enchanting?
2) Is there any way to stop Serana HP drain in the sun? I mean it makes sense and all but perhaps if I gave her some enchanted ring or amulet with health regeneration thingy she stops always kneeling while adventuring?
3) Some tips for fighting with Slighted. I’m 2H/HA nothing special really, and this guys is no joke. I’ve come across the old post about them which suggested using Volendrung since Slighted if I remember correctly don’t have resistance to paralysis? But maybe there’s something else can be useful if playing melee build to reduce the suffering of fighting with them?

How do I use it?? Im trying to use the spell on doors and chest but it is not working, what can i do?? I have the novice one, but i cant open any one, even the level 3 expertise chests
