Was fooling around with my legendary sigils when I came across a weird interaction with the "On elite skill" usage runes like rune of the zephyrite or rune of the ice. It appears the glyph of stars does not trigger the runes' skill usage. In my testing the rune of the zephyrite gives superspeed when an elite skill is used. I was able to use entangle and receive the superspeed but did not receive superspeed during or after the channel animation of the glyph of stars. I tested this effect in normal and celestial avatar AND in and out of combat with no superspeed given.
This got me thinking that there are some weird interactions of this glyph with some other runes such as rune of the druid which gives the +500 healing power during the channel of the glyph, not after. Where in the text of the glyph, it says after.
I'd like to compile a list of runes that interact weirdly with Glyph of the Stars in this report:
