Aptitude, as a stat, gives you bonus stats that act as bonus stats (IE: Do not count towards exceptional will, exceptional health, tactician.), but it does not have the drawback of being a bonus stat.

This being shown in the fact that burn does not shred bonus defense gained aptitude, hellflame uorate does not shred bonus res, poison damage somehow ignores the bonus HP gained from Aptitude's bonus to VIT and sanctity, overload does not gain bonus damage vs these bonus stats, etc. etc.

Now I get that aptitude itself isn't modded stats, but acts like they are, and that overload vs it would be kill, which is why the thread itself is more centered on the status effects, here's what I propose:

Poison: bonus VIT and Sanctity HP Bonuses do not ignore poison damage.

Burn: Burn now shreds bonus defense gained from aptitude (And RES if Hellflame Uorate is active)
