From Guild Wars 2 Wiki
Location in Lornar's Pass
- The griffons here protect a rare treasure at the far end of their rookery, but you'll need a bomb to free it from the chest.
Give me a bomb, and I'll get there.
- Be careful, this bomb is unstable. The smallest scratch could detonate it, so avoid combat. And move quickly- the fuse only lasts three minutes.
- Okay, I'm ready.
- On second thought...
- I have other things to do.
- The bomb is not needed to receive the jumping puzzle achievement. It is only needed to open the chest at the end.
- A teleportation stone located at the center of Griffonrook Run is used to get to her.
