Determination is something that is too powerful and dangerous to exist. It allows the user to pretty much decide the fate of all life in their universe, effectively turning it into their own playground where they can do whatever they want. With the ability of RESET, the user can go back in time to whatever SAVE point they made or they can go back all the way to the beginning as many times as they want. Most users start off doing pacifist runs, but eventually their curiosity in how far they can almost cross the line would lead them to do neutral runs. But inevitably they would cross the line and commit a genocide run eliminating all life in their universe and would throw away all their morals to do whatever they want leaving the universe at their mercy. To me Determination makes the two sayings of "No one man should have all that power" and "Absolute power corrupts absolute" true. So for my sake and safety for all life in my universe, Determination will get a super nerf that will make it a shadow of its formal self.
NERFS
[1] Once the user dies and uses RESET they are only able to go back in time within 24 hours.
NOTE: Initially the user can RESET at any SAVE point they marked before their death or go all the way back to when they were exposed to magic. The limit of time seems to be nonexistent of whatever SAVE point they made so I made the decision to only limit it to 24 hours.
[2] RESET can only be used once per month.
NOTE: The user can use RESET an unlimited amount of times so long as they are determined. But now once the user uses RESET it will be in a 730 hour cooldown or 1 month.
[3] Determination will grant the user a 10x power boost instead of an infinite power boost to destroy the universe and deal infinite damage.
NOTE: So long as the user is determined their potential will have no limit and as such their power will be infinite. Now their potential will be limited and their power will only achieve a ten times increase.
[4] The user will not become invincible with determination, as such they will DIE if they take damage while they have 1HP and if their soul is destroyed.
NOTE: The user can survive any fatal damage so long as they are determined. So I'm removing it.
[5] The user can only revive themselves once in their entire existence.
NOTE: When the user dies or has their soul they can use their determination to revive themselves. So as such they are only able to revive themselves once in their entire existence.
BUFFS
[1] No Buffs at all.
NOTE: I have no intention of granting any buffs to Determination.
