I've just opened the act 7 completion reward and I got Silver Centurion from 6-star nexus and Knull for 6-star basic. How good are they and do they need to awaken to be good ?
Silver Centurion- Doesn't need the dupe to do what what does best. Having the dupe makes him the best version of him. S.C applies 3 types of debuffs from hits- shock, plasma and incinerates. If S.C is duped, plasma and shock become passive. This allows you to bypass many nodes and immunities. S.C is also immune to shock and bleed while he has his armor up. He has access to slow on heavy and SP3. He can power drain from SP3. He has access to heal block on Sp1 and becomes passive if SP1 is used while regeneration is on. While locked on after throwing an SP2, his 2nd medium deals a large burst of damage. S.C has an easy rotation, stay close to the defender until SP2, Throw sp2 to lock on and spam sp1 after that to stay locked on. Tons of DoT damage. If he is duped and high sig, those passive damage effects last longer. Knull doesn't need the dupe but it makes him better as the more sigs you have on him, the more debuffs he starts with. Also able to heal throughout the fight. Everything that Knull does well, he can do unduped. https://youtu.be/-eEiyzG4X3Y
