This ability appears to be bugged and can just kill an enemy after one turn
I used this on the dragon in the final fight and on the 2nd turn when it's supposed to reduce the ability scores by an additional 1 point, the dragon would just instantly die due to having one of their ability scores reduced to 0. They had a status called "Atrophy" to indicate this.
It seems to be bugged and reducing the ability scores more than it's intended to as it should have only been reduced by 6 on the 2nd turn which wouldn't be enough to kill the dragon. This was also not an isolated incident as it worked the same way on other enemies too.
This bug will also kill the netherbrain turn one in the final fight even in Honor Mode. I am guessing it wouldn't work against an enemy who has all their stats at 12 or higher.
Checking the fight logs from Netherbrain:
- Orpheus used Abolsute Comsumption (Brain rolls DC19 saving throw, roll total if 17, failed save.)
- Brain gets Abolsute Comsumption (takes -5 ability)
- Netherbrain's turn starts
- Netherbrain (does all its actions.)
- Netherbrain rerolls the saving throw against Abolsute Comsumption, fails again. (And got the exact same result as on Orpheus' turn, 17 vs DC19.)
- Netherbrain lost condition Abolsute Comsumption (this was giving it a -5.)
- Netherbrain gains condition Abolsute Comsumption (but this time its at a -6.)
- Netherbrain receive's condition Atrophied.
- Netherbrain succumbed to death.
I am guessing what is happening is in the code the enemies stats are not healing right after the first buff is removed, so when the second buff of -6 hits, the enemy is at -11 stats and thus will instantly die. Netherbrain's Dex score is only 10. So it didn't have a chance. Interested to try against an enemy who has all their stats are 12 or higher, and see if the buff would be applied correctly since they wouldn't die because of the heal delay??
