Мафия 85. Lux in tenebris

what are these instructions to another player, telling them what to do and where to go?

This is a common occurrence here, and sometimes it's even helpful, so don't be surprised.

Initially, the Hydra was even stronger; I asked Ment to nerf it. Although, he might not have actually done it.
If you have to choose between Gek and a random selection from the list, the first option is better. Or, you can create a plan to capture the Hydra.
