Horizon of Darkness

-- News: these aren't rats, but some kind of homunculi or unidentified corpses, -- Henry said quietly. -- I don't think it makes sense to hunt each one, so let's just head straight for the boss, what do you think? And for now, battle formation minus Lin, Slime on the ceiling.

Zeykin (Lok) - Nikta (Kosh) -- Joe (Heroist)

                          Araël | Fayblup (Arandor, on the ceiling above Araël)

 Henry (Ment) - Radiel (Fragment) - Kalimor (Ples)

I don't know if we can use Ples, but I suggest this. Battle: Rad tries to hypnotize a rat with his flute, if successful, we surround it and attack simultaneously with auto-attacks to avoid wasting spell slots. And at the same time, we see how it behaves, whether the hypnosis is removed by attacks, and so on.
If not successful, then Radiel buffs Zeykin for physical development (?) and then we proceed depending on the situation.

Also, of course, I'm wondering if it makes sense to try to sneak up to the boss, without triggering the rats, but most likely not. Without Nikta's nose, it seems like a bad idea, we're practically blind.
