Casting entangle on whatever is left DC 15 Strength saving throw 20ft square after Petcans spell goes off on the remainder.

Bow fires of three shots with his imbued crossbow at the 3PW that look the most ready (first in initiative).

Attack: 19 Damage: 22

Attack: 23 Damage: 23

BA Attack: 8 Damage: 21

(all first d6 radiant the rest magical piercing)

Bow's 1st bolt nearly severs the stem of one and it reels precariously, leaning on another for support and to keep from falling over. His 2nd bolt whistles cleanly and strikes dead centre, half severing, half shattering the stem of another as it's upper portion topples to the ground lifeless. The 3rd bolt flies wide and embeds itself in the trunk of a tree.

Purplewrath DEX save vs. Sacred Flame : 18

The first group of 4 PWs is reduced to 3 and move to the edge of the foliage where the bolts were fired from and begin attacking Bow with disadvantage.

Attack: 10 Damage: 4

Attack: 13 Damage: 3

Attack: 19 Damage: 4

If any of those 3 attacks hit they also do poison damage, the following 3 rolls are to be matched to each of the 3 attacks in order. (1st to 1st etc.)

The initial attacks all do bludgeoning damage and if any hit they do the following poison damage (again, matching 1st to 1st etc.)

5

8

5

The next 3 PWs are reduced to 2 and move near the edge of the foliage and search for the source of the attacks, the first is to locate Bow and the next to locate Randall.

1st Search: 16

2nd Search: 3

Petcan's Fireball goes off and decimates the remaining 2 groups, the 3 PW and 4PW left at the end of the initiative order.

3 PW DEX save vs. Fireball: 19

4 PW DEX save vs. Fireball: 11

Bow's location is known but he currently remains unseen clearly, he can be targeted but with disadvantage. Randall's location is known and exposed visually to all the remaining PWs.

Petcan's Fireball totally incinerates the group of 3 PWs and roasts the remaining 4 PWs who writhe in agony but remain standing.

(Petcan's action is used up but you have the remainder of your turn, movement etc.)

Tempe's held action goes off.

4 STR saves vs. Entangle:

Randall's held action goes off.

(Sorry for spamming posts but there was a lot of bookkeeping to take of.)

Of the 4 groups of Purplewraths this is a loose update:

The 1st group of 4 are now 3 and attacking Bow.

The 1st groups of 3 are now 2, one couldn't reveal Bow although his location is known, the other revealed Randall and all PWs can currently see him.

The 2nd group of 3 are all burned to a crisp (dead).

The 2nd group of 4 are badly burned and Restrained but will finish off the 1sr round of initiative right after Petcan finishes their turn.

(Petcan doesn't have to move or do anything else, just a reminder that you only used your action. Let me know you're good with that or want to do anything else on our turn.)

Petcan is all good, ready to move on. His Warding Wind is up though (just a reminder)

The 4 restrained PWs try to break free from their fellow plants, the grasping weeds and vines that hold them fast.

STR check: 17

STR check: 10

STR check: 17

STR check: 13

2 PWs break free and move to engage Randall in melee (melee range only, no actions left this round).

Petcan's Warding Wind has a variety of effects, I am placing Bow outside it's 10 feet range because logically he would not want his hand crossbows to suffer. Everyone else please mention in your turn post or a separate post if you are inside the 10 foot range or outside. If Bow wants to move inside he can but his hand crossbows will suffer.

Initiative Order:
Round 2

(Tempe is up. Randall is next)

Tempe with the radiant glow of the sun flies within 30ft of the ones who are near Bow and rains death from above 2 attacks each PW

 Attack: 10 Damage: 6

16 Damage: Unable to parse dice roll.

1 ki point flurry of blows

9 Damage: 6

11 Damage: 10

He then moves away towards the center of the PWs moving to 35ft high. 

Radiant Sun Bolt

Randall:

Standing next to Petcan in the Whispering Winds, Randall conjures a glowing mace to smite the Purplewraiths who just came up next to him, then lashes out with Lightbringer as well.

Spiritual Weapon:  Attack: 22 Damage: Unable to parse dice roll. plus Bless: 1

Lightbringer:  Attack: 15 Damage: 9

Zenodor flies a little higher still (to 60ft to stay out of their range, but able to get back into 30ft range within one move if necessary), and decides to blast whichever plants look already weakened using Eldritch Blast. So one blast each for two injured/scorched ones, to try to finish two off.

Bolt 1: Attack: 15 Damage: 9

Bolt 2: Attack: 16 Damage: 13

Bow will take aim at the three PW that are closest to him, and will indeed not be in the wind that surrounds Petcan.

Attack: 25 + Bless 2 Damage: 20

Attack: 16 + Bless 1 Damage: 25

BA Attack: 9 + Bless 3 Damage: 21

Crit damage as it apparently didn't go off due to how I included Bless: 5

Tempe blasts 2 more PWs near Bow, they wilt and die. Randall's spiritual weapon strikes one down and Lightbringer claims another. Zenodor rains down death on the 2 PWs that weren't Restrained and were closing on Randall. Bow fires off 3 bolts with similar results to the previous round, the 1st two shots claim PWs and the 3rd shot clunks solidly into another treetrunk.

(There are now only 2 remaining and they are the ones who are Restrained after being fireballed.)

STR check: 18

STR check: 14

One breaks free and moves to attack Randall:

Attack: 15 Damage: 5 bludgeoning damage. And if the attack hits Randall also takes 6 poison damage.

Initiative Order:

Tempe moves to a more advantages point and looks like goku aiming his radiant bolt at the still restrained one Attack: 13 Damage: 8

Then sends another at the one who freed itself 9 Damage: 5

Then if the restrained one is still up he'll use his searing arc (burning hands) Dex DC15 Fire damage 13on it using 2Ki
