If I get a crit hit while my archon is on cooldown face, does it reduce it by a second? I can't tell by looking at it, but it seems like it doesn't. Could just be my imagination though.
I have no idea if it does or not but it clearly reduces the CD of your ability hotkeyed to #1. Also the coefficient for the beam is 0.25 so only 25% of your crits from the beam will activate CM.
This would be relatively easy to test, in theory. Activate Archon and start a stopwatch. Run around a high population zone and mow down enemies for 90s or so. Then cancel Archon and wait for the CD to refresh. If it refreshes before the stopwatch hits 2 min (assuming you're not using Evocation or the rune that reduces the CD) then it does work. If not, it doesn't. Just make sure you dont hit anything after you cancel the Archon buff. I'd test it myself but I don't actually have a watch that works.
I can confirm that CM does actually reduce the CD of Archon while in Archon form.
To test, I used Force Armor buff, without galvanizing ward, which has a convienient duration of 2 min, the same as the Archon CD. I cast the armor then immediately activated Archon. After running around the Keep for 90s or so, killing as many mobs as possible to extend the durations, I cancelled my Archon form and found it came off CD before the buff wore off. Sometimes it was only 10s difference, others around 20s, so it might not be a lot, though my crit is getting low at around 30% with Scoundrel. This means CM is a very viable alternative to Evocation for those who have issues keeping Archon form active.
I don't think the teleport rune does get reduced CD from CM, but I don't know for sure. It just never seemed to, though the Arcane Blast does, or whatever the other Archon ability is with a CD.
