Celtic Heroes

Just wondering if there is a list somewhere of the timers for the meteoric bosses. Tried to search but nothing. I'm including bladewing, spearhorn and ironscale in murky. Are they all 20 minutes? Flo btw says Rockbelly is 20 mins but normally spawns abt 27 mins. Would be grateful for any replies.

They have too large of windows to time, you're better off just running a cycle and killing them all and then just restarting.

Doomclaw 7 min
Bonehead 15 min
Redbane 20 min
Goretusk 20 min
Coppinger 20 min
Rockbelly 15 min

These are all taken from the latest version of the timer app. Haven't tested them but they seem good. Sorry, don't have timers for the others you mentioned but they're probably right around the same as these.

Of course there are spawn windows to consider as well so I'm assuming these are the start of those windows. I forget how long the windows are for these guys....so not super helpful.
