Mega Lightning Chest
Mega Lightning Chests are tied as one of the rarest chests in Clash Royale. Through a normal 240 card chest cycle a player can expect to unlock no Mega Lightning Chests as they are not part of the typical cycle. Mega Lightning Chests will guarantee a player several epic and rare cards. The higher rank the player has will produce more epic and rare cards. Mega Lightning chests do not contain any common cards and will take 24 hours to unlock. If a player chooses they can immediately unlock a Mega Lightning Chest for a maximum of 144 gems.
When a player is ranked in P.E.K.K.A.'s Playhouse or above the player will have a high chance of unlocking a legendary card. If the player is ranked in Spooky Town or above the player is guaranteed a legendary card.
