All of the worlds in this game have their own endless-mode stage. For instance, the first world (Pridefall Kingdom) have the “Fields of Endless” – situated below the 9th level on the game map.There are different tier levels to beat when playing the endless mode. You’ll have to survive longer in order to claim higher rank and their concluding bonuses in the game. For instance, to reach Rank 2, you’ll have to survive the endless mode for at least 2 minutes and 30 seconds – which will, in return, reward you with 50 gems. If by any chance you’ll win and skip a higher tier level rating when playing the endless mode, all the skipped tier level rewards will be available for you to claim at the Quests menu.
Here are the corresponding Rank Levels, Required Survival Duration, and their Concluding Rewards:
Rank 2 – 2 min. 30 sec – 40 gems
Rank 3 – 5 min. – 90 gems
Rank 4 – 7 min. 30 sec – 150 gems
Rank 5 – 10 min. – 200 gems
Rank 6 – 15 min. – 250 gems
On the more recent update to the game, you may choose to spend your endless mode key (rewarded every day), along with a raid ticket (earned by watching ads – maximum of two raid tickets per day) to instantly earn power items that you can use to forge better buff spells to help you advance in the tourneys. This is primarily devised for players that have successfully beaten the highest rank (surviving 15 minutes) on the endless mode – to automatically earn the available item rewards on their pertaining rank level (as higher rank will normally drop more potions while playing) without having to play the missions.
