A list of every most status effects and enemy actions in the game. (A few bullet-specific buffs are missing until I encounter them in-game.) Hopefully, it will eventually become a complete glossary.
I have also included notable characteristics of each icon, such as what the number beside the icons mean, how long the effect lasts, and the order of certain effects when they happen simultaneously.

It may remove one of the following: Shield, Armor, Attack Buff, etc.
It would most likely be easier to ask the developers directly.
