The issue is mostly that in the show the fruit is good for two main reason:
- Stealing souls (which can be replicated in minecraft with damage etc.)
This is completely doable and I have done before, the funnest part to me would be on cooldown have an ability where you just have to click an entity to steal the soul. For entities like sheep and cow it'd be simply instant death and you get x amount of points. While with player you steal x amount of health permanently. What does this mean? If they have 57 max health and you hit them with the ability they for example permanently now only have 52 max health. Of course you can do that with yourself
Tl;dr I love it and can definitely be done
- Animating inanimate objects
This is the big issue, we see the user of the fruit 'putting' souls into inanimate object. Which made me think we could of course make an entity for every block in the game and entities. Right click it with ability, poof you got an inanimate object. Do I think it's impossible? Neh nothing is. Do I think it's an absolute time sink for only 1 fruit? Absolutely.
Then the next idea comes, well what about just "making" an entity like doppelganger ability or the ability from the ito ito no mi... You know just "you can only spawn 1 type of entity max 2 or three" Well to put it simply... it's boring you always make the same enemies and the good thing about this fruit is that it's super versatile BECAUSE you can put the soul in a bullet or in a tree. Put souls in anything that can help you specifically.
So this is the part to me that's the biggest issue.
Besides these issues (mostly number 2) I still think stuff like Heavenly fire ore Indra abilities are cool... But cannonicaly don't make sense. She had to put a 'soul' in a cloud or fire to do that. So then again I love the abilities but that damn second point is there again. How the hell we gonna make it so you can give life to a cloud? That'd be cool get a 'cloud' entity you can fly on etc.
tl;dr this fruit will be one of the literally latest fruits ever to be added to the mod by sheer amount of work or there will be very clever workarounds found out
P.S. I am VERY interested in making the fruit I absolutely LOVE 'raise an army' type abilities. Adore Geto's curse technique, the guy from Black Clover raising the dead, always play Necromancer when I got the chance to etc. This fruit is def in the top 3 fruits I'd ever eat (besides jiki and gura) because I just love the idea behind it. So if I can work on it I'll probs do it!
