Certain effects can only go on certain equipment. No Shield Charge, as far as I know, can only be applied on two-hand weapons.

Actually, I don't believe that Shield-less Charge is on two-handed weapons.

I'm pretty sure it's only on one-handed. (Meant for dual wielding.)

I'm pretty sure it was meant for two-handed weapons.

headgear, shield, accessory. apparently only available to r1 reforge too. 1 level. counter with opponent's attack feels more useful, has two reported levels, shows up on clothes and heavy armor, and occurs on r3 reforge and above.
