Updated again!
The world will be much more populated now, with different races spreading across the world but settling primarily in particular areas. Most civilized races have some kind of special ability now, and their automatic abilities now work with secretions so you don't have to remember to activate them first.
Toads: Still glass cannons.
Koopas: Can withdraw into their shells, parakoopas can fly, magikoopas have a special movement speed (Teleport) that uses a lot of energy but allows them to move really really fast and can use magic attacks, burly koopas are big and strong.
Shy Guys: High agility.
Bandits: Special movement speed (Super Dash) that uses a lot of energy but is good for running jump attacks or making a quick getaway.
Bumpties: When prone, they slide. This has a long buildup but a high top speed and uses no extra energy. Also good at resisting blunt attacks. Terrible attack power though.
Frog People: Poison spit, poison sweat, and hop instead of regular running, which has no build up but lower top speed than sprinters. Also natural swimmers.
Mole People: Extravision, stat boosts, and the ability to sense creatures at a distance, but only when underground.
Piantas: Really strong, and stronger aboveground. No good armor though.
Nokis: Fast swimmers and agile.
Squeeks: Very small and can crawl as fast as they can run, making them good at sneaking. Even if sneaking wasn't already overpowered. Also have very sensitive noses.
Bub-ulbs: Stronger aboveground, can use Pollen Nap to put creatures to sleep. Can also sense plant-based creatures.
Doogans: Natural appraisal skill, good endurance for long merchant journeys.
Craws: Can fly.
Bob-ombs: Kaboom! You can also use weaker, non-fatal explosions that will throw everyone around but won't kill you.
Goombas: Can sense and analyze any monster created through alchemy (i.e. that contains Shining Coins). Different symbols show up depending on the monster's "tier".
Shamans: Frost webs, lightning bolts, charms and curses. Weak fighters though. Watch out, they will use curse as a negative social reaction so don't get them upset. It's temporary though.
Kongs: Really fast climbers. You can also choose their size now, Greater Kongs are really huge.
Kremlings: Sharp teeth and tough skin. You can choose their size now too.
Humans: Larger than most races, combat trances.
Koopas will build dark fortresses again, which will be ruled by generated demons. Unfortunately, this means that Demon Koopas will generally not become their leaders. That's upsetting, so I made Demon Koopas playable as an outsider so you can go and try and conquer a Koopa kingdom yourself (or just terrorize the world, you cheater
)
