There are a couple of issues related to the damage reflect hazard, some are in another post but the Psalm-Code one I could not find it being reported anywhere else.
The Psalm-Code Doctrine "Reduces Damage Reflect from enemies by +80%" is not working. Damage seems to be the same with or without it.
Also, damage reflect does not seem to be working correctly, in general. The numbers are significantly higher than what they should be. It also bypasses shields.
This would probably be ok if the Psalm-Code was working, but the combination of these two issues essentially make damage reflect awful. Please either consider removing damage reflect from the hazard pool entirely (this would be preferred, it's just conceptually bad), or fixing one or both of the above issues so that it is playable. Thanks!
