Well this is not describe anywhere , how did You get this info ?
Well this is about chance to purify not AAR so super unclear
I would just write : each death spore reduce AAR by 10 %Sound simple
This is big difference because chance to purify is also added to apocalypse and there it is very specific . Here it seems to be way more generic then it is described @Kabam Miike is it right ? Maybe worth to change
I am not a mastermind to figure out what Kabam wanted to say it should be clear
