What Does The Glow Do?

[BoatCreeks]

I notice my armor and sword start glowing like orange and red but always go back to blue after a while. I don't realy know what it does or how to trigger it.

it does extra damage if you'll have it glowing while attacking (you need to push button for some time to have it full charged). it disappears if you'll get hit. It's probably explained in how to play.

It's sort of an extra level of HUD

Blue is your default state.
Red glow means you're on low health (less than 4 bars, I believe)
Green glow means you've just healed.
Orange glow, if you've charged your sword in close quarters, causes your next hit to do 5x damage, but the glow is lost after taking one hit. Charging takes a while, so only try it immediately after knocking an enemy down.

Hope this helps!
