Description

Features

An actually fun and engaging difficulty curve

• Please beware. This hack WILL test your ability and skill as a nuzlocker.
• Trainers will start easy and get progressively harder. From Brock onwards, random trainers will pose a genuine threat to the current power level of your team if not handled correctly. Opposition will not disappoint you with boring level up movesets that are sometimes completely useless. Instead, they will come fully prepared with fine tuned movesets that may include coverage and utility moves tailor-made for those Pokémon and that point in the game, and the farther you get into the game, the more common held items will be. You will have to pay attention to every fight if you don’t want to lose any of your precious Pokemon.
• The number of Pokemon on each trainer’s team has been adjusted.
• Gym leaders will defend their reputations ferociously, using teams significantly stronger than the average trainer in their area.
• Similarly, wild Pokémon have been balanced to provide you with appropriate resources to get through the hordes of trainers that await you in this hack.
• If you fail to see your way through the game, simply start a new save, with an entirely new iteration of Kanto to overcome!

(Items in the overworld are NOT randomized. The items you find are specifically designed to help you in the current stage of your journey.

QoL

• This game has the mandatory infinite candy item for this genre to help you grind your Pokémon close to the level cap. Beware that this game does NOT have hard level caps and that you will be expected to manage your experience on whatever Pokémon the game provides you. (Note: infinite candy will be given to you upon getting the Pokedex from Prof. Oak)
• There are cheap max repels and full restores available at every pokemart. Poke Vial and infinite repels are planned to be added as they provide much better QoL comparatively.
• Move accuracy on 90 and 95 accurate moves was raised to 100. (Did anyone say technician fury swipes meowth?)
• Buffed catch rates on many Pokemon.
• Alternative methods of catching Pokémon, such as fishing and sweet scent, have been removed. Surfing lends the same wild encounters as tall grass. You do not need to worry about delays. Moreover, all Pokémon in a wild area are of the same level,l and different floors of a dungeon have the same wild Pokémon. The only way to potentially manipulate your wild encounter is through abilities like magnet pull which still work as expected.

Modern Mechanics and a limited dex

• This game offers up to Gen 9 mechanics and moves. However, enemy Pokémon are limited to Gen 4 and prior for better scope management.
• In this prototype release, the player only has access to Gen 1 Pokémon and Pokémon that relate to them via evolution (such as Elekid and Happiny). The finished hack will give the player access to Pokémon from Gen 4 and prior as well.
• There are no late gen gimmicks or regional forms in the game.
• Exceptions to modern mechanics include explosion and self-destruct being in their pre-nerfed Gen 4 state. Also, experience gain has been reverted to its Gen 4 state as it makes experience management a LOT easier for the player.

Slight story and overworld adjustments

• The story is a lot more linear with less ways to branch paths.
• Many Team Rocket events have been snapped away from the hack. The only Rocket admin I fear is Freezai.
• Routes will have more mandatory trainers in them than usual.

NO NONSENSE

• The hack features NO BUFFS OR NERFS to base stats and abilities on any Pokémon. However, good hidden abilities have been swapped with one of the Pokémon’s regular abilities to give the player potential access to them.
• Opponent Pokémon will only use moves that can be potentially learned as per Gen 9 (Thanks showdown teambuilder).
• All non branching evolutions are changed to level up. No need for stones, friendship, …etc. The hack is very liberal with changes to evolution levels to make the experience more interesting.
• Gym leaders do not use healing items such as potions.

A Learning Curve

• As you play more randomized seeds, you will grow more familiar with the difficulty curve and the tricks that enemy trainers pull on you, as well as the enemy AI. Even if every attempt is random, overall knowledge of the game will carry across attempts and make you, the player, better and better every single time.

THE LIFE BARGAINS

• What the heck is a “Life Bargain”? Well, it’s a unique mechanic introduced in the Nuzlomizer to spice up your nuzlocke experience. If you want to know more, feel free to boot up the game and find out for yourself…. Let’s just say you will use your Pokemon as a resource but in a way that is….different from usual 🙂

Current version limits

• The game is only playable up to Erika, past that point, the rest of the game is in its vanilla state.
• I am yet to fully revamp learnsets and evolution levels on obtainable Pokémon. It turns out that wild Pokémon require a lot of work to get them correctly. the state of the game is still very fun to nuzlocke as is. (And yes I am calling my own romhack fun and I’m not sorry for it)
• There is a bug in the game where if you wipe, the game crashes, which is funny for a nuzlocke hack, but unintended nonetheless and will hopefully be fixed soon. If you want to mess around, please save the game somewhat often (or just don’t lose 4Head).
• Don’t try to register your infinite candy item to use with the SELECT button. It will case the game to crash.
• Not all overworld items have been laid out yet.
