Ok, I wanted to clarify (these are my opinions, mind you) the tiny difference between a Perseverance soul and a Determination soul, since many people seem to think they are practically the same.
Perseverance is the will to keep doing the same thing over and over again even if initially it doesn't work because you hope to reach a certain outcome. Determination instead is the will to reach that outcome, not necessarily with the same ways though.
I'll make an example based on the battle system in Undertale bc it's funny.
A Perseverance soul will pick a method to survive the enemy, be it by killing, attacking then sparing, running, or acting, and then stick with it for the whole run. If they meet an enemy that isn't compatible with their way of fighting, say for example Mettaton and running, they will try to survive as long as they can and keep trying to run away.
A Determination soul instead will try to defeat the enemy in all the ways they can. No matter the procedure, the important thing is the ending. So they will try other things too of course.
There is a thin line between these two terms, so I thought I'd make the difference clear for all of those who didn't want to search on Google. You're welcome.
