Dryad Assassination

[Caleb The Cold]

My group is currently running a campaign in which true names are quite a big deal to magical creatures (fey,celestials, etc), and due to party infighting a dryad has recently learned my true name. As such the only possible solution to prevent this from being a problem and risking having half the summer court knowing my true name is to violently eliminate the dryad. Right now I'm thinking of just firebombing it's tree while it isn't paying attention, but I imagine someone here will likely know a more entertaining solution.
The party currently is at level 7 so in a straight fight we could probably just stab her, but I'd rather deal with this on my own.

[Lathiira]

Well, you could always learn hers. Or, for that matter, make it clear that if she does anything stupid, her tree will make an excellent dinner table as well as fuel for the fireplace. "Mutually assured destruction" and all that. Though really, how powerful is a truename in your campaign?

SPECIAL ABILITIES
Tree Meld (Su)

A dryad can meld with any tree, similar to how the spell meld into stone functions. She can remain melded with a tree as long as she wishes.
Tree Dependent (Su)

A dryad is mystically bonded to a single, enormous tree and must never stray more than 300 yards from it. Most dryad trees are oak trees, but other trees function as well (often having subtle influences on a specific dryad’s personality and appearance). A dryad who moves 300 yards beyond her bonded tree immediately becomes sickened. Every hour thereafter, she must make a DC 15 Fortitude save to resist becoming nauseated for an hour. A dryad that is out of range of her bonded tree for 24 hours takes 1d6 points of Constitution damage, and another 1d6 points of Constitution damage every day that follows—eventually, this separation kills the dryad. A dryad can forge a new bond with a new tree by performing a 24-hour ritual and making a successful DC 20 Will save.
Wild Empathy (Su)

This works like the druid’s wild empathy class feature, except the dryad has a +6 racial bonus on the check. Dryads with druid levels add this racial modifier to their wild empathy checks.
Woodcraft (Ex)

A dryad has a +6 racial bonus to Craft checks involving wood, and is always treated as if she had masterwork artisan’s woodworking tools when making such checks.
ECOLOGY

Environment temperate forests
Organization solitary, pair, or grove (3–8)
Treasure standard (dagger, masterwork longbow with 20 arrows, other treasure)

There's a not insignificant amount of time before the lack of having a tree will kill them, so they will need to be isolated or incapacitated for up to 13 days (though the average is 4).

However, 27 HP is not much, even at level 7. A character focused on damage could easily kill in one round with a cold iron weapon.

Modify Memory is an option, but Will is the highest defence, so you're still better off stabbing.

What class are you?

You would also have to lock the bond, or otherwise prevent the dryad from bonding with another tree

Planeshift the dryad to the astral plane then cut the tree down.

If you're doing that, might as well just wait until she's in the tree, and then planeshift the tree to the plane of fire..
