Nrnhoned what weapons are worth having it on?

ZeFeZ

Currently got Swords only researched, as I mostly run Magica DW builds but curious if daggers or GS are also worth researching?

Wollust

Swords for Magicka Dual Wield or sword & shield.
2h sword for Magicka builds (there exist a formula that tells you at what point your pure damage is higher on a 2h than on DW)
Destructionstaff
Restostaff

The other ones are more nice to have in case you need to craft 9-trait stuff.
