I forgot that there are no canon made up sciencey data about what a soul contains and keeps track of.
So I, the most sane and normal person about Undertale and world building made notes.
Monster souls are composed of magic, the very combination of every monster’s being.
4. Positive / Negative energy (in place of cholesterol)
1. The average monster doesn’t have any
2. Undyne has a determination level of 0.2 (only monster who naturally has determination)
3. At a determination level of 1 monsters start experiencing determination sickness.
4. The threshold of determination before turning into an amalgamate is 2.5 (the amount it takes to get a fallen down to move again.
5. Humans have a determination level of 10
6. Negative energy in soul increases
7. Wild Magic (basically it spontaneously goes out of control)
8. Pain where soul usually rests
If you have three or more of these symptoms, something is WRONG.
Positive and Negative energy - Mainly added for Dream and Nightmare purposes but also, makes enough sense.
1. Ideally, there is a balance of 65-35 with the 35 being negative energy, with a margin of error of about 5%
2. Negative energy has good and bad forms, negative energy from day to day life is fine, but external stressors based on emotions, life style, and events cause the bad negative energy.
3. There is a such thing as too much positive energy, and having too much usually means mania.
4. The margin of error for mentally ill folk is more like 15%
Magic Levels is more like Magic affinity. Higher affinity the more compatible you are with Magic outside of race specific Magic. EX: bone Magic being a race based Magic, and Telekinesis being non race based.
The beauty of magic that I go by soft magic systems and I don’t need to explain anything else about it.
Anyways that was your ramblings of a sane person.
