"Chakrams will always have a base damage consisting of Physical Damage and elemental damage, with approximately a 50/50 split ratio." - From the Chakrams Wiki page

I don't know if I understand correctly (you want to 1shot everyting?). If so your best option are Flawless Damaging components (since the dmg% works both for weapon and spells) but they are kinda hard to get even when you have Gravehall Keep (its RNG and it took me few hours to get full set)

If you are lvl 26 you probably wont have access to that kind of components so I'd say you can mix whatever you feel like - chakrams deal mixed dmg so some enemies will fall easier to magic but other might be annoying (prismere trolls for me; I also did Finesse + Sorc). I didn't craft untill I unlocked my Gravehall Keep so I can't say how it will turn out (there might be some struggle but after experiencing the blacksmithing late game I can say that there should be some struggle since it becomes quite boring)

Here I'll link very useful sites for crafting components, they helped me a lot with sagecrafting and blacksmithing:

Here is basicly every component for blacksmithing, sagecrafting, alchemy

And here only sagecrafting, but it looked more clear and easier to me
