Essence ofUndertale Monster

Your body is made of magic and hosts your new, monster soul. It can take a lot of punishment and regenerate, it's really hard for you to die or get crippled due to incidents. But attacks with intent have a lot more effect on you, on your soul.

You have the ability to mold your magic into different shapes and give it different properties for self-expression, fighting or other purposes.

You can attack souls directly with your magic or affect the physical world instead.

Your mental state has a great effect on your body and physical health. But your mental health no longer depends on the functions of your body.

You have the ability to use different 'soul modes' on other creatures with souls or yourself, but you are more knowledgeable and skillful at affecting human/monster souls.

You have great skills in utilizing your magic in unique ways. Like blue and orange attacks, healing via magic, etc.

You can use your magic as part of the creation/crafting process to give things you make some unique properties. Like creating monster food, which can heal and give buffs.

You are an ageless boss-type monster and have a spark of [Determination] in your soul.

As a monster you can absorb human souls to gain exponential increase in power. However, they can oppose your will and you should find some way to actually restrain their resistance. Try not to explode by biting more than you can chew.
