I’m curious how some people’s heros are 4 stars I’m maxed out at level 70 but none of mime are 4 stars
You can get up to 5 stars + epic star by collecting hero shards (shops, elite campaign, dungeon, contests, packages)
My 5 star characters are Sparkle Pony, Scion and Hex Witch. Scion is easily done by beating the bosses in the Boss Dungeon, you get Sparkle Pony from Endless randomly in chests and the easiest currency to farm is Crusade Tokens to get Hex Witch.
I’m a F2P better and part of the Guild Wrecking Crew. It helps a lot when people in the guild spend to get Gifts for the Guild
