Has anyone had the chance to beat on a Blasted Lands mob with the Dragonspine Trophy? I assume it functions similar to the Hourglass of the Unraveller; something around a 30 second CD on the proc.

I'd be curious to know how often it procs when wailing on a Servant of Allistarj for an hour.

Just a random catch here, on The Night Blade. Your data calculates procs per swings.

302 procs / (per) 2113 swings = 0.1429, or 14.29% chance on hit.

For clarification:
2113 procs per 302 swings = 6.9967, or almost 7 procs per each swing.

Just some transposed variables it looks like, nothing to sweat about.

Wow, that makes it the new number one trinket by a good 5-6 DPS (over Bloodlust Broach) for a rogue. Based on that data, it looks like it procs once every 45 seconds in a static fight; this sounds about right as that's the average proc time for the Hourglass and it wouldn't surprise me if they used the same mechanic.

I was the person who made the WoWHead post. I've seen the Dragonspine buff refresh itself before, so if you're referring to the "cooldown" on the Hourglass proc, I don't believe it does.

And yeah, it's an absolutely ridiculous trinket with SnD and specials factored in.

Ok, did another set, this time in Blasted Lands. Same thing, no OH equipped, no skills used, and I counted each time it refreshed after 3 stacks. This is the recent screenshot, there were 15 additional refreshes that don't show up (the ones I counted.) So that's 243 procs in 1032 hits (23.5%)

Here's the Procwatch from the first test (1080), I forgot to get one from last night.

I haven't seen this much anywhere, and since we do have 3 rogue threads, i felt this one would be the best one to post it in. Have any of you have any experience with the riftmaker? I am not as concerned with the damage, but more about the proc.

How often does it proc? Does it stack with Thunderfury and or Thunderclap? Do you guys find it worth using at this point?

Doesn't stack with anything, unfortunately. I haven't used procwatch on it, but I'd put it at 1ppm. I suppose it has it's uses. Another rogue and I were mainhanding it for our initial Gruul learning, where we used a druid tank for Blindeye. The proc was up a lot.

With the change to Thunderclap in defensive, it kinda went from casually useful to pretty useless. I'll keep it around in my bags for heroics tanked by bears I guess, for hard hitting bosses maybe.

So is there no way to change the proc % in the spreadsheet without Pf doing it? :/

You can edit it locally; if someone tracks down Bleedo, he could probably get updated versions onto his site.

Where would I do that in Excel?

Actually, I used a flat reduction of 100 armor for the proc as noone had the weapon when I made that guess. You can change the flat amount at 'unbuffed dps'!m36 and 'buffed dps'!m36.

I am trying to get another version out with the new skill by tomorrow, and I'll look at changing the flat amount to a more reasonable level. Unfortunately, making it proc based on the sheet would cause circular references and I avoid those. I'll try to come up with a decent estimate later tonight based on the data given in this thread.

The dragonspine trophy is something for someone else to model and figure out its mechanics (ie does it have an invis cooldown etc) as I have no desire to implement "hard" mechanics anymore.
