As either name suggests it is a game mode in which the player creates a team that will face an unlimited amount of teams until the player retires or their team is defeated.
When a team is defeated, another immediately takes place and the battle continues with the player’s current status and the board unaltered.
Difficulty and rewards would scale with teams defeated:
Epic troops start appearing on 3rd round, Legendary troops on 5th and Mythical on 7th.
Minimum troop rarity increases every two rounds, i.e, on the 1st round all troops are at their base rarity, on the 3rd round common troops are ascended to rare and the rest remains the same, on the 5th round troops are ascended to ultra-rare and the rest remains the same, until on the 11th round all troops are mythical.
Enemies begin with no traits and unlock 1 every two rounds.
Every 15 rounds enemies receive a 50% increase on stats.
Gold, Souls and Maps obtained from spells will still be capped as usual, but those obtained from 4+ matches, killed enemies, and cascades will not be limited by the cap, but they will not be counted for spells.
*A random traitstone is awarded for every round. Every 5th round guarantees a runic or better traitstone.
These scaling numbers are certainly just ideas, but regardless, I believe it would a fun addition to the game.
An issue with this that has been raised is sandbagging on the first few rounds to build stats up higher. Something like the hero weapon that doubles a troops Armor, you could boost your team to 999 armor each. And if one of the troops is a Gard or Rowanne it becomes trivial to just plow through each round.
Would need to reduce any player troop to the start stats each round.
I love the idea of an endurance-style battle, and would love to see a mini-game made out of it. The problem as I see it is that the best strategy would be to bring a bunch of buffing troops and stall out while things are still easy, scaling up all stats to their cap before starting battle. Any such mini-game would need to take steps to disincentivise this behavior lest it become the most-optimal, least-fun path to success.
