Taste the rainbow! Tracks if you have a curse (purple), magic debuff (blue), poison (green), or disease (sickly yellow), as well as if you are on or below half health (yellow), or on very low health (red). For people with tunnel vision, and/or who want a low-impact HUD display.
Wrote it for myself so that I could know when I'm suffering from a debuff/DoT, whether or not I could cleanse it, and to not go throwing myself into the thick of things when I'm on 10% HP.
