# Battle Generation

The battle difficulty, denoted by its tier, is dependent on 2 factors:

1. The total number of creatures you own
2. The [size](https://arrivant.gitbook.io/project-eluune/player-journey/prelude-live/prelude-limited-event/prelude-creatures/size) of those creatures

Each higher tier has stronger enemy creatures with higher sizes and multipliers, but also with a higher quality of rewards. Upon entering these battles, players must strategically place their creatures against specific enemies, taking advantage of the [classes](https://arrivant.gitbook.io/project-eluune/player-journey/prelude-live/prelude-limited-event/prelude-creatures/class) to defeat as many of the opponents as possible.\\

Above, the example battle shows your enemies on the left and each of the creatures you own on the right. The small boxes under each enemy creature indicate the slots where you can assign your creatures to fight the enemy. You can see the win odds which are dynamically calculated for you when you place new creatures. After placing all your creatures, you can click "Launch Battle," which returns the results page with your rewards.\\

**Daily Battle Tiers**

Daily battles have 10 tiers in ascending order of difficulty and rewards received. Each tier will contain creatures of a higher size than the previous battle. As you advance through different battle tiers, you receive increasing tiers of [ingredients](https://arrivant.gitbook.io/project-eluune/player-journey/prelude-live/prelude-limited-event/ingredients-for-crafting) as rewards. Note that battle opponents are generated based on the characteristics of your inventory, not on the tier of the quest or rewards. If there are two players in the same tier and one has a 10% larger inventory, that player would get stronger opponents.

**Daily Battle Rerolls**

You can reroll a daily battle once per day.

**Daily Battle Rewards**

Rewards from battles are in the form of [ingredients](https://arrivant.gitbook.io/project-eluune/player-journey/prelude-live/prelude-limited-event/ingredients-for-crafting) and creature [XP](https://arrivant.gitbook.io/project-eluune/player-journey/prelude-live/prelude-limited-event/prelude-creatures/xp).\\
