Was just wandering through regular MM yesterday, with a level 31 Loki and his summoned minions when one of the demon bosses dropped a Legendary Scroll for me!
Although I play the game a lot (not quite as much since my quadruple bypass in August..yet ;) ), it is extremely rare for me to get such an item...and was quite the surprise. The yield included a Cyclops (dup, but always great for an ultimate upgrade), Luke Cage's Earth X- costume, Pelt of the Sacred White Gorilla unique and Spider-Clone Serum...extremely pleased!
Just wanted to share my good fortune with the community and to also let folks know the level of my character and my location when I got lucky! :)
