⚔️Serberia Auto-translated

The pies don't work in battle.
I suggest Air moves to the cell with Dani and attacks T4. When T4 dies, switch to T10 if initiative remains.
Anders attacks T2, hoping for a critical hit.

I'm not sending it; I'm waiting for Ples or another smart and attentive player.

You can enable auto-battle.

Perhaps it would be better for Air to switch back to Tier 2 upon the death of Tier 4. Positioned above Tier 2. This way, she can retreat from the line of fire and has a better chance of finishing it off (whether the Rush ability works or not).
Anders should then focus on taking out Tier 10.

Air attacks Tier 4.
Anders attacks Tier 2.
If Tier 2 is still alive, Air moves above Alessia and finishes him off. Otherwise, he moves under Tier 10 and attacks it.

If any of the dendroids attack Renold and his health drops to 30 or below, the Chalice is activated immediately afterward.

Anyway, if we win, you have a 95% chance of survival, provided Rohei survives as well.

When they tried to revive Daniel, the 5% chance came up.

Rohei himself was in the coffin.

Throw a fireball at the spirit.

I thought they weren't going to touch him, right?

We decided to take a risk, as the situation is very unfavorable for us. However, the situation only worsened after our decision.

Added 5 minutes later

Anders attacks T10.
Eyr attacks T10.

Perhaps the spirit will spawn new creatures if we kill these ones. And so on, endlessly.

maybe we're supposed to "die" as part of the story?

I think there's something or someone in that corner, and we need to get someone there. The problem is that there aren't many candidates for such a risky maneuver. I planned to send Veseroda to the enemy's rear when the opportunity arises, to check what's in that corner (if anything is there), and if nothing is found, he'll finish off the remaining dendroids and get all the experience for the quest himself.
