Magics that equal gm level?

[Oderus Urungus]

Isnt plain force weapons equal to gm weapons?
Same with Hardening armor being equal to gm armor?

[Mikel123]

Might adds +3 to damage
GM adds about +4
Force adds +5

So it's somewhere in between the two. It also adds durability, so realistically there is virtually no need to keep any might weapons (unless they have accuracy modifiers, charges, etc.).
