How about a Rare, an Epic, and a Legendary to choose from (they don't have to be new).

The challenge now lasts maybe 48hrs instead of 72hrs.

The challenge is to use your stamina to fight as many battles against this monster and collect cells depending on the number of survivors in each fight (like War Coin format).

This gives players a chance to fight monsters in order to win its cells. Over a period of 48hrs, even average players would surely collect enough cells to craft it.

I like the idea of each time you fight the monster, it will have different random immunities, so no fight will ever be the same.

@Clackers maybe. Isn't that what the survival dungeon does? Rather try for that than 48hr challnge. Work gets in the way

@shazzy Survival Dungeons are something different...as only high level players can attempt it.

I like this idea, ull fight against bot that have random runes and relics, the more level you pass, the less random bot will get(easy > hard)
Like 1st one ( easiest) youll get 3 L cells ( not random the event about 1 monster that get voted on fb)
On each level sucess youll get 3 cells
And last one ( hardest) youll get 20 cells
At the end that will be 80 cells= you can craft him
Or
this can be on elemntium ( special edition )
Only happen 1 time every 2 months
