Hello there.
This chapter explains some mechanics related to race,magic and some lore changes.
Racial traits- each person has a race and each race has its own advantages and disadvantages, like sans was a skeleton that is a undead race , they don't need food or sleep but have low defense and take double damage from light attribute attacks, healing or blessing them deals damage instead of healing.
Magic attributes- each magic has a attribute and if the caster casts a spell of a magic that his race complements then it gets a overall boost and opposite can also happen for example, a lich casting dark magic will have higher damage than normal while light magic will be better weaker.
Stats and stat multiplier: stats are base of a person's power and can be increased through training or other rarer items like equipment and consumables.power of each stat point increase with its number as well as it's difficulty to gain.Stat multiplier boosts stat effectiveness not the stats themselves.
Str- strength of a person(physical ofcourse)
End- sum of defensive capability of a person and his stamina level.
Dex- includes both agility(speed) and reflex speed.
Mana control and mana capacity- same as their name.
Willpower- mental stamina and resilience ( status and pain resistance)
Lore changes- the barrier is stronger than it was in the game, the souls are now used to control rather than break it. There will be a storyline for outside of the monster kingdom. Asriel was the only person killed during the war. Chara and frisk are two souls in one body and both are girls( w for shippers).
Monster core- the monsters of tier 3 or below level races have a monster core that is main and only vital part of their body. If anybody part takes damage, the damage is done to the core not the body( like the original game where no matter the attack only the health goes down and there is no chance things like insta kill if you aim at the head for those with a core)
