Hi there! Is it only possible for you to read reviews? I just see the Stars, but I don't find the access to the texts. So I guessed, no one can read the others' reviews. But that's maybye just because I'm new...
As for the "Cripple": The first time I use it, I get charged (Stamnia). Also the enemy can counterattack. Then the second time (there might be exceptions) it shows the red text, smth like: "XY already reached limit of movements." No counterattack, no charge of stamnia, also no attack from other foes, they stand still, except when it takes really long, then sometimes the foes can move or attack. (Very rarely) This repeats, til the enemy is dead. (As long I have a melee weapon). Also this text repeats. Somehow it paralyzes everyone. .. Hope I could help you!
