Carefully pick up the mine.
Sanjeliza paddles the boat up to the mine, and bends over the side to interact with the mine. There looks to be many hair-sized trigger spines around the outside to react to boat hulls. She successfully keeps herself from triggering any as she tries to unhook the mine from a chain keeping it underwater.
However, when the chain comes undone, and the main comes to the surface she can hear a very distinctive clicking sound.
The reactions are fast enough to clear the worst of the mine's blast radius, but they are each temporarily deafened from the explosion. Shrapnel fall also hits each of them, giving them some damage. Also, they are out further into the centre of the room.
Cleric: Whoever's after us? Probably heard that.
Also, those descriptions I promised:
The elf is a male who stands about 5'7" with long pale blond hair, and gray eyes. He wears robes made of a leather-like substance that looks white. Or would look white if he hadn't been in the dungeon so long.
The cleric is a female human standing about 5'9" with long black hair, and brown eyes. She wears a breastplate that comes down to her waist, and under that she wears a black gown that reaches her calves. Anything that isn't covered in metal is protected via a mage-armor field. The breastplate is also likely simply for show.
