Danganronpa S: Ultimate Summer Camp/Battle

Battle Mode, also known as the Tower of Despair, is a main gameplay element in in Danganronpa S: Ultimate Summer Camp. The player creates a party of four characters and defeats waves of increasingly powerful enemies to proceed up the tower, collecting rewards as they go.

Early Game
In the early game, it will be difficult to level up characters and proceed up the Tower, even with high rarity cards. However, every 10 Hope Fragments(from different characters) that are collected from the board game mode will trigger a special event with significant permanent rewards. As such, it's worth simply replaying the board game with each new card(does not apply to different level cards of the same card e.g. doing both normal and swimsuit Makoto would only count as one) you unlock, enjoying the Friendship events, etc, even if you aren't focusing on min maxing every single card.

Every 20 Floors of the Tower, you will unlock the ability to purchase the Monobeast scrolls in Development mode for only 10 monocoins from the 1st Island shop (provided you have previously beaten that Monobeast), which will allow you to proceed to the higher level islands with more powerful stat boost squares much earlier and getting closer to LVL 99. As such, it is worthwhile to alternate between the Development Mode and Battle mode because it is cyclically rewarding.

Efficient Monocoin Farming
Monocoins for the basic gacha machine can be efficiently farmed by repeatedly replaying Floors 2-10, particularly Floor 10, because the boss has a higher Monocoin drop rate. Ideally, if the player uses a team of four Intelligence cards with a high level magic skill, this can be accelerated further, and then additionally accellerated if the cards are of a higher rarity/efficacy. This can also be exploited using a modded programmable Nintendo Switch controller, because the action of restarting the battle can easily be repeated by spamming the A BUTTON while using the in-game auto battle function, for over 100 Monocoins per hour.

Gold Monocoins can technically be farmed from Floors 110 and 120, however the drop rate is significantly lower than regular Monocoins. They are realistically only farmable using a rapid fire controller, because even with optimal conditions the drop rate is only approximately 10 per hour.

Equipment Crafting
The following items can be crafted and worn by characters to boost their stats during battle. The items are crafted using items dropped from monsters throughout the dungeon. There are five equpment types, and each character can equip one item from each category.

Enemies
There are 26 main enemy types, each with a number of alternate forms in different colors that increase in power. Some of these variants have an alternate eye color, which denotes their elemental weakness (eg, if they have a yellow eye, they are weak to lightning). Not all enemies have this elemental weakness, but it useful to look out for.
