The door opens into a large room the ceiling is suspended by four columns, spaced around a calm pool of water with a ring of tiled stone around it.
The pool has a giant octopus ready to attack you. It begins with 20 hits (2 tentacles) rolling 2d6+10 on its first attack. On its next attacks it adds one more tentacle, 10 hits, until all eight tentacles are destroyed, or you are dead
First Round Attack: 2d6 + 10 ⇒ (4, 3) + 10 = 17

Brenda scores a 6, doing one hit against the octopus, but her total of 15 is less than the octopuses 17, doing two hits. Luckily her buckler stops the damage
You fight bravely against the initial attack, and now that you know what you are up against you prepare for it to get worse before it gets better.
The octopus does not add i/2 it’s hits to further attacks, but adds another tentacle + 10 hits
Octopus hits – 29
Second Round Attack: 3d6 ⇒ (5, 4, 4) = 13
