-7% Critical

That 7 protection comes from Shield Mastery, small. Hidden Stat bonuses aren't seen in the character stat menu. Also, 7 Prot =/= -7% Critical; its 3.5 Prot = -7% Critical, since every 1 prot = -2% crit.

Its a deduction of critical chance from enemies. If it added protection, it would also affect damage reduction and wounding, which it doesn't.

I see, I thought I had remember seeing shield change my screen but I guess not. Regardless, I think it's clear that "-7% critical against enemy attacks" is pretty unclear phrasing, but where do we change it?

Template:StyleWeapon

However, due to its extreme complexity, I highly advise against editing it and let a professional handle it.

actually that field in question is contained in Template:StyleEquip since it appears to be a shield property.

regardless, hopefully changing "critical against enemy attacks" to "to enemy critical chance" is perfectly clear

I'd suggest "-7% to enemy's critical chance (no protection increase)".
