Can these MVPs be put into an "MVP Room"?
Sealed osiris should guarantee a revive when you first die on a map that's loaded (not for event maps obviously). After that it should be % based at 20%.
Sealed orc lord should rather be 10% chance to break parts of the body. Wrist Break, Ankle Break, Knee Break and Waist Break should be the 4 things used here on top of the external bleeding and original effect. Possibly add Max HP +30% as well as you're freezable with this on. Might give it an exciting place with the current rota of cards available for armor. Crit wounds 5 and long range reflect are a bit too much.
Sealed doppelganger should just give you 196 aspd since the formula for the original one is rubbish.
Sealed moonlight should give an effect that causes a 10% chance when hit to activate a free speed potion effect for 3 seconds and a 1% chance to cast land protector when being hit.
Sealed eddga should also have an effect where you drop a level 5 demonstration on yourself at a 5% chance.
