The pyromancer quickly comes to the dire realization that the fire magic he expected to instantly incinerate the party hasn't even yet brought one of them down yet. The recognition of the horrible pain from Zuu's eldritch energy wracking his body comes and bringing him near to death comes only slightly later. After appreciating that there is no way this fight could end positively for him, the pyromancer flees. Rather than running though, the being bizarrely uses his apparently functional goat legs to hop froglike from one branch to the next and escapes through the trees rather than under them.

The pyromancer use its action to dash and runs 60 ft. away.

After Nauta runs away, the pirate attacking him looks for the next best target, and comes to the unfortunate decision of directing his eyes towards Fid's dance. The pirate becomes frozen in place by the primal quality of the chanting and seems almost mesmerized by some unidentifiable horror at the sight. Neither the pirate nor an onlooker could fully understand what is going on, but it is clearly causing the pirate to freeze.

Pirate A is paralyzed by Fid's Hold Person spell.

The other pirate though is much too concerned with other matters to focus much on Fid though. Upon recognizing that he is horribly and most likely permanently injured, going up against an opponent clearly more skilled than him, and being drowned in a swarm of flies, the pirate rather reasonably decides that this just isn't worth it. The final pirate escapes from the area with the use of his goat legs, much like the pyromancer just did.

Pirate B resists Fid's Hold Person spell and then takes the disengage and dash action to 60 feet. away.

It is your turns now. Here is the stats post.
