Battle facilities

Polished contains 2 battle facilities, the Battle Tower and the Battle Factory. They're both heavily inspired by the main-series games' namesakes. Crystal already had a Battle Tower, but Polished's version of it generally works more akin to modern Battle Tower versions.

General

Each facility challenge run consists of 7 trainers. As you win more battles in a row, the challenges get harder over time. All your Pokémon are set to level 50. Eggs and certain Legendary Pokémon (Mewtwo, Mew, Lugia, Ho-oh, and Celebi) may not participate. All species must be different. In the Battle Tower, all items must also be different. Opponent Trainers get their Pokémon from this table: https://github.com/Rangi42/polishedcrystal/blob/master/data/battle_tower/parties.asm

Pokémon sets in the facilities are grouped into 4 tiers; D, C, B and A, which roughly corresponds to the Pokémon's strength. A Trainer gets a team composed of 3 Pokémon from these tiers, with the exact tier depending on their "difficulty level", which varies between 1-8. This also correspond to the Battle Points reward you get for winning the battle. The difficulty levels are as follows:

1: CDD 2: BDD or CCD 3: BCD or CCC 4: BCC or BBD 5: ACC or BBC 6: ABC or BBB 7: AAC or ABB 8: AAB

The rental draft gives 6 Pokémon from both options instead of giving 2 groups of 3 at random. For example, the initial draft for your first challenge will give you a selection of one B-tier Pokémon, 2 C-tier Pokémon and 3 D-tier Pokémon (shuffled at random), corresponding to a difficulty level of 2.

Successfully clearing a challenge run gives an item reward.

Battle Tower

In the Battle Tower, you choose 3 of your own Pokémon that obeys the rules for participation as stated above. With these 3, you battle 7 trainers in a row. Successfully clearing all 7 trainers will, on top of the Battle Points you get for winning against a Trainer, also give you an Ability Patch, which allows you to switch a Pokémon's Ability to its Hidden Ability or vice versa. The AI in this facility is always running at the maximum strength. The EVs for the opponent start at 0 and increase by +16 for each victory, up to a maximum of 252.

The difficulty level and BP reward of the opponents you face are as follows:

Challenge run 1: 1, 2, 2, 3, 3, 4, 5, 20 total Challenge run 2: 2, 3, 3, 4, 4, 5, 6, 27 total Challenge run 3: 3, 4, 4, 5, 5, 6, 7, 34 total (Tycoon run) Challenge run 4: 4, 5, 5, 6, 6, 7, 8, 41 total Challenge run 5: 5, 6, 6, 7, 7, 8, 8, 47 total Challenge run 6: 6, 7, 7, 8, 8, 8, 8, 52 total (Tycoon run) Challenge run 7: 7, 8, 8, 8, 8, 8, 8, 55 total Challenge run 8 and onwards are all at difficulty level 8, and a successful run gives a total of 56BP.

Battle Factory

In the Battle Factory, you battle with rental Pokémon instead of your own. At the beginning of a run, you are given 6 rental Pokémon, called a draft. You choose 3 different Pokémon species (but they are allowed to have the same items) to enter a challenge. Each time you defeat a Trainer, you may trade one of your Pokémon with one that the last Trainer used. All Pokémon here always have the maximum 252 EVs. The AI here runs at a lower strength for the first few challenges, and will reach its maximum strength starting with challenge run 5. Successfully defeating all 7 Trainers in a run will, on top of the Battle Points you earn for defeating each Trainer, give you a Mint Leaf, which will in the future allow you to exchange the Nature of one of your Pokémon.

Opponent difficutly table

The difficulty level and BP reward of the opponents you face are as follows:

Challenge run 1: 1, 1, 1, 2, 2, 2, 3, 12 total Challenge run 2: 2, 2, 2, 3, 3, 3, 4, 19 total Challenge run 3: 3, 3, 3, 4, 4, 4, 5, 26 total (Tycoon run) Challenge run 4: 4, 4, 4, 5, 5, 5, 6, 33 total Challenge run 5: 5, 5, 5, 6, 6, 6, 7, 40 total Challenge run 6: 6, 6, 6, 7, 7, 7, 8, 47 total (Tycoon run) Challenge run 7: 7, 7, 7, 8, 8, 8, 8, 53 total Challenge run 8 and onwards are all at difficulty level 8, and a successful run gives a total of 56BP.

The draft's difficulty level corresponds to the difficulty level of the 6th Trainer you would face in that challenge run. In addition to this, for every 6 times you swap one of your Pokémon with one that the last Trainer you battled used, your initial draft's difficulty level will be increased by 1. For example, if you were to swap every single time in the first challenge run, the 2nd run's draft would give you Pokémon corresponding to difficulty level 4 instead of difficulty level 3.
