My wife sees RSL reward offers while playing other mobile games, and I'm unsure if they are realistic. Usually, there is a deadline of 30 days, and the rewards start easy but get more challenging for the rewards to be used in the other game. So, for example, Finish one battle = 77 rubies... but then you get Reach Level 10, Upgrade 1 hero to 5 stars, upgrade two heroes to 5 stars, Open three void shards, Upgrade 1 hero to 6 stars, open 6 Sacred shards, as a Free to Play is this even doable?
