|Before the hydra attacks|
The hydra only has one attack, and it chooses to spend it on Andrej. It rolls a 16 on a d20, hitting AC 0 ... and 2d8 causes 11 damage.
That too is a wound. Andrej is pushed back to 2815, staggering but still in it - stunned, of course.
Lukas takes a point of damage from his wound.
Lukas' spell is ready to go. Enrico may load; Sofia and Ahmet take what action they will.
