Pokémon Mystery Dungeon: Explorers of Sky Playthrough 85: Entei's Infernal Finish

This is the final part of this playthrough, I have achieved Guildmaster Rank, which unlocks Inferno Cave, which is a very tough dungeon filled with Fire, Poison and Ghost type Pokémon. Only the leader can enter, up to eight items can be brought with you, and there are annoying Random and Grudge Traps, and the Pokémon there are high leveled, and it doesn't help that it is a 30 floor dungeon. In this dungeon, we accept a Challenge Request from Entei, the Legendary Beast who is said to have been born from a volcanic eruption, and that a volcano erupts when it roars.
As the rest of the description, I recommend watching the full video before reading past this point of the description.
Inferno Cave is a very tough dungeon, and as for the Challenge Request with Entei, it can happen between floors 15 to 29, and I used the Wonder Mail S Generator for the Challenge Request.
The Pokémon you can encounter in this dungeon are Gulpin, Gastly, Numel, Cranidos, Drifloon, Magmar, Shuppet, Vulpix, Rapidash, Typhlosion, Noctowl, Misdreavus, Aggron, Swalot, Camerupt, Haunter, Rampardos, Drifblim, Magmortar, Banette, Torkoal and Gengar. The Ghost types can be annoying to deal with, Misdreavus can use Mean Look and Perish Song, Drifloon and Drifblim have Ominous Wind, Gulpin and Swalot can use Toxic to inflict Poison, and Rampardos's Head Smash is a dangerous move to deal with.
Entei is at Level 65, and like the other Legendary Beasts, this is a challenging opponent, as it can use Lava Plume, Extrasensory, Swagger and Fire Fang for its possible moves. When recruited, Entei can be a great team member, as it is recruited at a high level. For level up moves, Entei can learn Fire Blast, Calm Mind and Eruption. It has good access to TMs like SolarBeam, Iron Tail, Shadow Ball, Overheat, Stone Edge and a few others. With a partner that knows Sunny Day, Entei's SolarBeam, Flamethrower and Eruption can be dangerous when paired with Calm Mind.
Entei's Exclusive Item is the Flare Fang, which is like Raikou's Bolt Fang, where Entei's moves are not affected by the target's Reflect or Light Screen. The Flare Fang can be found on floor 25 of Zero Isle South through a locked door.
At the end of this dungeon is a Deluxe Box which contains an IQ Booster, which increases the IQ of anyone holding that item.
