If you get the Darkpromise Chance Blade 2H Sword for Chosen from LV, and equip it, the rending Blade Ability shows Grey in the Bar. And its says allways by using equire Great Weapon.
And the Prog of this sword that you increast heal if your Healed, will not shown in the Combat chat log, even a prog symbole or something
This is still the case for Darkpromise Changeblade after the 12/09 patch went live: Rending Blade greyed out, yet can be used, with warning 'requires great weapon' poping up every time
