If You Boil It And Strain It

You had one sunrod that Scowlen gave you. I wasn't sure if you had another.

Without a rank in Knowledge Architecture and Engineering, Kaspar can only see that it looks as if something sheared through the catwalk suddenly. Perhaps some spell, back in the war, when there was fighting in these tunnels.

(Nice spot check!) You can see a crossbow bolt sticking out of the body's back, between the should blades - recall that it is floating face down. You can also see that the ladder on your side, which is to say the set of metal rungs bolted into the wall of the vat going down into the vat, has less grime on it that other surfaces. As if it was used recently.

Kaspar can just, just touch the floating body with Castille's shortspear, if Kaspar will stand at the edge of the sheared part. As he approaches it quivers a bit, but otherwise remains stable. To 'tag' the body with the spear, Kaspar has to make a touch attack against an AC of 5.

While Kaspar extends the spear, Humfred is goggling at Castille. "Me? Swim? In that?" Humfred gasps. "Do you have any idea of how deep and filthy - oh I will not, only a warforged would be swimming in that!" Seeing Castille's look he explains "Warforged are immune to diseases and they do not need to breathe. One could be in that vat right...Did you hear something?"
