Arena Tournament, Round 47: Aramail vs. No

[Bayar]

Upon my turn, Round - 6,

I try again.

(1d20+17)[25] DC 23
(1d20+2)[22] AC 10
(4d6)[16]

And need a question answered by the refs:

What is the climb DC for the walls ?

Depending on the answer, will continue my turn.

Edit: You got fried by a ray, the water boils around you and the sharks come to feast upon your cadaver.

Still interested in an answer from the refs though.
