Pakalchi Entangling Train and Escape

[rkotitan]

My group is rapidly approaching Deathhead Vault in the Crimson Throne Hardcover and will end up having to fight a Pakalchi Sahkil.

The creature has ability called Entangling Train

Text:

Creatures adjacent to a pakalchi must succeed at a DC 20 Reflex save or become entangled in its vines for 1 round, and count as tethered. Entangled creatures take vine damage automatically each round they’re entangled. Creatures are no longer entangled if the pakalchi moves away. The save DC is Constitution-based.

So if a character gets snared by this entangle (which is tethered) do they pretty much have no option of escaping other than the Pakalchi moving away, escape artist, teleportation, gaseous form, or killing the Pakalchi?

I expected some kind of STR check or perhaps an ability to cut themselves free but I don't see one.

Just asking to avoid the inevitable rules discussion coming up.

Thanks for any help.

Entangled characters can still move at half speed. Also, the effect only lasts one round, after which they'd get another saving throw to avoid having it happen again.

They are tethered, so you are correct in that they can't move. They are only entangled for one round though, so the next round they are not entangled, but they will (probably) still be adjacent and so have to save again.

Beyond the methods you have noted, freedom of movement would also let them escape.

I don't know of any tethered condition. Where might I find rule text confirming that you cannot move while entangled by this ability?

Here it is

Entangle:

The character is ensnared. Being entangled impedes movement, but does not entirely prevent it unless the bonds are anchored to an immobile object or tethered by an opposing force. An entangled creature moves at half speed, cannot run or charge, and takes a –2 penalty on all attack rolls and a –4 penalty to Dexterity. An entangled character who attempts to cast a spell must make a concentration check (DC 15 + spell level) or lose the spell.

Thank you for the answers guys. I appreciate the quick response.
