The rightmost head will turn towards Andrej. The middle head will look at Lukas and say, without attacking, "Why must you fools always disturb us? Did we eat your child?"
The first head snaps out at Ahmet - but through a particularly bad coordination, the second head moves so quickly and ruthlessly that it smacks the first head out of the way. As a result, the first head rolls a "1" to hit ... but the second head rolls a natural "20." The hydra rolls to see if it is triple damage, and it is not - however, twice 9 damage is 18, that the creature does on its first round against Ahmet. Ahmet is stunned, and staggers back to 2213. He has a wound now, that will bleed 1 hit point damage per round until it is healed or bound (noted by a red star).
The head attacking Andrej rolls a 17, hitting Andrej rather definitely and causing 6 points of damage. This doesn't stun Andrej.
The party can take what action they will. It will require 1 movement point for Maximillian to discharge his spell; he can then move up to 3 afterwards, but can't physically attack the same round he discharges a spell.
To hit one of the creatures heads in direct melee, Party members must be in 2308, 2309,2310, 2311, 2312 or 2408. The head partly in 2312, that struck Ahmet, is already pulling back to 2412. It is possible to move into the 2500 column, but not to do so and attack.
Remember, because of the water, it requires 2 movement to enter a new hex. It does not cost a movement point, however, to retreat from a hex next to the heads (as it normally would for melee), and although the creature is huge, unless you are next to the body there is no incidental damage.
