How does this work, really?

First use encase in stone, to root them, then use detonate stone works to direct dmg on them, also I belive this work with another perk line, engi and soldier i think, not to sure.

Encase in stone roots yourself. I think you're thinking baout Stoneworks, which is in the adventurer perkline Outdoorsman.
So no detonate stoneworks unless you are cooperating with an adventurer that has that line trained...

Why couldn't you use stoneworks yourself and detonate stoneworks?

If you are an adv yourself you can...

wonder if this is supposed to be a payback towards someone rooting you with Stoneworks
however it seems more likely to be one of those never-fixes

just another weird chain, that's all. And one of the easier ones tbh. The first part gives 7k AC all, but roots you, that inspires you to continue the line, where the second and last part of the chain deroots you and has a high dmg hit. Wanna see something that makes even less sense? check out Gutting blow: Special requires Grasp and Bearhug and Grip of Colossus to already run.The effect of this Special is a high direct damage when in sabretooth or pitlizard form....the line chain requires you to root yourself, after getting behind the mob to use the perk, then somehow continue the chain, rooting yourself, after which you can finally use the high dmg hit..maybe, if it happens to work out that way. heh. would love to hear a success story for that 1 :P

As an advy with outdoorsman 3 & mountaineer 5
1) Encase in stone roots me + the crit decrease & AC buff
2) Stoneworks does AoE root and removes other root from me exept encase in stone rooting effect
3) Detonate stoneworks hits target for 1700-3000 (with rrfe) and removes (stoneworks) root. I am still in encase in stone root. (ranged ftw)
- gotta be fast with detonate stoneworks because target can use free movement to clear the stoneworks root and then it's too late to detonate.

Well for starters, th Freak Strength perk lines stun, not root, both you and the target. Once it wears out (the stun) the target is still effected by the perkline itself, letting you perk the next line, and the next. Only Grasp needs to be from behind, the rest just has to land really. ^^ (at least this is what I've discovered from using this particular perkline with my agent.)

Oops, scratch the last one, GoC needs to be from behind.. hehe. ^_^

Attack time 5s could be doom for an agent but also can be more DD

Soo, now with 17.8 patch this does not require stoneworks perk from outdoorsman line to execute, but also got defensive check 100% AR vs 90% duck, where before only req to hit with this was the stoneworks root running on target.
Also recharge has been nerfed from 15sec to 6 minutes, which is the same as encease in stone recharge, so this can't be used anymore during encease in stone recharge time when someone else pops stoneworks.

umm... i just used this perk with my soldier... no advy. u can use it withouth stoneworks... as the description says.. 'Special requires either Encase in Stone or Stoneworks root effect to already run. Is more efficient if Stoneworks root effect already run'.. if u got encase in stone running u can use the perk. doesn't say stone works HAS to be running.., just does more dmg if it is running.

Seems bugged with my character, I've been Detonating like there's no tomorrow, but root isn't removed...

Ah, my bad, didn't notice which root the description specified ><

It also seems to be removing roots on target, not on self.
