Overview

In Backpack Battles, which has been receiving a steady stream of updates lately, the speaker plays through a full run aiming for a "pet-packed" build. The setup fights with a lineup of creatures such as slimes, dragons, and birds, and the speaker describes it as being "like a Pokémon battle." The video walks back through the run, including the rough patches, while explaining the thinking behind the build.

Early Game: Two Torches and a Stamina Benchmark

The early goal is to make two Torches. A Torch can be crafted from a Wooden Sword and Coal, and according to the speaker, you can have both within one or two rounds. As for the stamina cost of two Torches, the speaker reckons that, given cooldown reduction and the opponent's shields, a single Banana is about right. Once the Torches are in place, the rest is about collecting pets.

The first one to join was a slime. However, since it had been a while since the speaker last played, they got the placement badly wrong and went on to lose three in a row from there. From this mistake, the speaker concludes that the slime's number of activations should take priority over the Coffin's effect.

The Green Slime and Collecting Coal

Turning the slime into a Green Slime requires a Mushroom. The speaker notes that you'll want the starting Mushroom at this stage, so they recommend holding onto it if possible. After collecting a second Mushroom, the materials for the Green Slime were complete.

Coal becomes desirable from the midgame onward, but it also becomes harder to find from the midgame onward. For that reason, the speaker gave up on winning in the early game to some extent and gathered Coal while trying not to lose too much. The speaker says that once the Green Slime is complete, fights become stable, so it might be a good idea to manage your lives with that point as a benchmark.

The Red Slime, Eggs, and the Dragon

The speaker got a second slime and decided to raise this one into a Red Slime. The speaker considers a two-slime setup quite strong, and wanted to use that window to buy an Egg and raise a dragon. However, an Egg was slow to show up. For the unique item, the speaker chose the Hair Ornament. They say they picked it by process of elimination, since the other options are underwhelming for this build.

Finally, an Egg appears. When a Torch or Coal is placed adjacent to a burnable item, on the next turn it transforms that other item without being consumed itself. Using this mechanic, the speaker placed the Torch adjacent to the Egg. At the same time, the materials for the Red Slime came together, and the Red Slime was completed. After that, the speaker bought a second Egg and also reserved a card. The speaker thought they would surely lose the round while holding two Eggs, but the Red Slime put up a good fight and snatched a win.

After the first dragon hatched, the speaker combined it with cards. The speaker rated their backpack layout at the moment the dragon was born as "5 out of 100." With that in mind, they recommend placing the Torch between the slimes to increase the slimes' activations, since the Torch is the fastest to trigger among these items. With the speaker's life down to 1, the dragon evolved.

Synergy Between Heat, the Hair Ornament, and Mana Orbs

According to the speaker, this build accelerates through Heat, and the Hair Ornament also boosts healing. That is why Mana Orbs and books pair well with it, and the speaker says that eventually even a single Mana Orb builds up about as much mana as one book.

The evolved dragon was powerful, and the combat log showed the dragon, the Red Slime, and the Green Slime all dealing damage evenly. The speaker values how a balanced spread of damage sources reduces weaknesses and makes the build more stable.

The Deck as a Device for Drawing Combination Materials

The next goal is evolving the second dragon. Since the current cards are hard to make good use of, the speaker treats the deck purely as a device for drawing combination materials. While the deck is on the board, cards are laid out, but they take up space that could go to other items. So the speaker explains that it's important to put the deck out only when there's a card you want, and that you should put it away for a while when only useless cards can come up. The speaker drew the card they were after, so the deck's job ended with the next battle.

Generally, your strength drops in a round where you combine items, but the speaker states that this dragon's power more than makes up for it. With that, both dragons evolved. Going forward, the speaker is considering directions such as accelerating further with Gloves, adding books with the leftover mana, and adding more slimes.

A Four-Dragon Showdown and Stuns

The opponent in the next battle had a similar build, and between the two sides there were four dragons. According to the speaker, once Heat reached 15, stuns started triggering, and from that point on the opponent was stunned the entire time. The Coal gathered in the early game helped in building up to 15 Heat. That said, the speaker personally recommends going for stability with two dragons, since four dragons is more than you can make good use of.

Around this time, a bird and a slime joined the team naturally, and the speaker says, "It's starting to feel like a Pokémon battle." They add a joke that the bird is basically a Flying type, and the slime, with its branching evolutions, is essentially Eevee. The advantages the speaker cites for this dragon are that it consumes no stamina at all and, since it attacks at range, it doesn't take counterattacks either, so acceleration comes with no downside.

Into a White Slime with the Lightsaber

The speaker decided to combine the newly added slime with a Lightsaber simply because it seemed fun. They knew they were certain to lose this round, but since two Knives were left over and it would be a waste not to use them, they decided to use them up here. The opponent also had a two-dragon setup, and partly because the Lightsaber was heavy, the speaker lost, but the slime evolved into a White Slime.

A bird also showed up, so the speaker bought it. The bird's cooldown is a short 3 seconds, and it does its job by pecking the slimes to trigger them. While noting that favoring the Red Slime would normally be stronger, the speaker deliberately favors the White Slime here. Even while having its effects removed by the opponent's book, the White Slime racked up around 12 "misses." The speaker explains that because of the fire effects, the debuff bar is barely visible during combat, but looking at the opponent's debuff bar in the latter half of the fight confirms that the White Slime is doing its job.

The Final Battle: 67 Heat and a 0.31-Second Cooldown

Despite messing around early on, the speaker survived to the final round. The last opponent had what the speaker called a "good old-fashioned" poison build. The Green Slime countered the poison, and the dragons handled the other element, so the match turned into the dragons continuously breathing fire and burning everything down.

In the end, Heat reached 67, and both dragons' cooldowns hit 0.31 seconds. By the speaker's calculation, in a 10-second fight under these conditions, the opponent would only be able to act for about 3.7 seconds. Looking at the log, the speaker confirms that they seem to have successfully neutralized the opponent.

The pets, led by the dragons, carried the team to victory, and the speaker looks back on this setup as a fun build in which cute animals wage heated battles.
