Varan will move three paces to the right and send a crossbow bolt at the parrot (in case it's a familiar or some other danger).  Attack: 29 Damage: 10

Keyleth uses Insightful Fighting on the pegleg Wulgar, then runs to him and attacks with a sword.

Insight: 25 (min 24)
Attack: 18 Damage: 32

Each of Wulgar's strikes barely catch in the pirate's form as only the final of Avarice's blasts connects. All three of Mulligan's daggers sink in, while Varan's crossbow bolt causes the parrot to poof from existence in a puff of colorful, red-and-green feathers. Keyleth's attack connects (No way to roll higher than 32). Ragnar dashes into melee. 

Undeterred, the peglegged Pirate draws a rapier and pulls a cowl over his face before sending rapier jabs the party's way. 
Bonus Action - apply Cloak of Invisibility. 
Rapier Attack (Wulgar): 21 Damage: 41
Rapier Attack (Wulgar): 23 Damage: 13
Rapier Attack (Keyleth): 20 Damage: 17
The pirate is no longer invisible. 

The real Avarice continues to blast pegleg Wulgar with three beams of purple crackling force.
Eldritch blast: 27  Force: 12
Eldritch blast: 20  Force: 7
Eldritch blast: 13  Force: 9

"My condolences on your better half," Varan shouts to the dirty pirate Wulgar.  He then loads and fires another crossbow bolt.  Attack: 15 Damage: 12

((I don't think I was moved 30' towards PegLeg as I noted last turn?  I should be or be able to get to melee range this turn?))

     With the pirate no longer visible, Mulligan looks for blood falling from his wounds or the sound of labored breath or something to use to target some wild attacks before swinging his rapier about in the area of his best guess...  ((Perception: 19 ))

Assuming attacks at disadvantage...

Rapier Attack: 20 Damage: 11

Rapier Attack: 15 Damage: 12

...well I forgot to attack at Dis but seems he is visible anyway so no Dis anyway.

Wulgar feels warmed up and ready to keep swinging.  He flanks his alter self and he keeps chopping at the Peg Leg Wulgar, which he takes particular offense to..

Great axe 1 : Attack: 20 Damage: 18 

Great axe 2 : Attack: 18 Damage: 20 

Divine Fury Damage : 8 

Additional brutal critical damage :  13 

Keyleth slashes at the pegleg Wulgar again.

Attack: 25 Damage: 35 piercing
Attack: 20 Damage: 7 piercing

Although the pirate-esque figure manages to dodge some blows, it's Wulgar's axe that finally puts the pegleg down. 

The clock begins to churn. You have three rounds to do with as you wish - heal, buff, prepare, etc, before the next bout begins. 

Avarice tries to levitate to a spot with dim light where he turns invisible (One with the Shadows) awaiting the clock to strike again.

     Mulligan would try to collect the three daggers he threw at Pegleg, but I assume ones from previous clock ticks are out of reach.  Otherwise, no prep needed.

Varan intends to maintain concentration on keeping greater invisibility up on Keyleth.  He will take the following steps on the turns available to him...

1. Spend a bonus action to convert a second level spell slot to 2 sorcery points.
2. Spend a bonus action to convert a second level spell slot to 2 sorcery points.
3. Spend a bonus action to convert 6 sorcery points into a new 4th level spell slot.

Wulgar moves to the middle and prepares to attack the next active imposter depending on where the clock hands go.  He comes out of rage, and then activates rage again right as the hands start to change.  "Let us out of here!"

Keyleth simply stands at the ready, scanning the clock-battlefield with a watchful eye.

Notes to self: Avarice/invisible, Wulgar/rage, Keyleth/invisible

What time is it? 10
Tick, tock: 5

The clocks whir, rotating towards another of Mulligan's and Ragnar's copies. This form of Ragnar seems to have taken a priestly line of work, while Mulligan's alter form looks suspiciously typical. 

Everyone's up. 

Appearing floating above the clock the real Avarice blasts the suspiciously typical Mulligan with three beams of purple crackling force.
Eldritch blast: 29 Force: 13
Eldritch blast: 22 Force: 15
Eldritch blast: 25 Force: 9

If Wulgar has the sense that the false Ragnar means us harm (and they seem to thus far), he walks up to him and swings his great axe at him.  

Great axe 1 : Attack: 27 Damage: 20 

Great axe 2 : Attack: 16 Damage: 17 

Divine fury, on the first hit :  12 

     Moving in besides Wulgar, Mulligan too will strike out at the false Ragnar.

Rapier Attack: 22 Damage: 8

Rapier Attack: 18 Damage: 14

Sneak Attack damage to whichever attack hits first (if either): 13

And Defensive Flourish used to add 6 damage to the first attack to hit, and to my AC until my next turn...

...

     Due to my Piercer feat, once per turn I can preroll piercing damage from an attack.  I'll turn the first attacks damage from a 9 to a 8

     One a critical hit, like the second attack, I get to roll one additional damage die.  So add 7 to the second attack's damage please...

...

     If both attacks hit, and I think they do, that should be 55 total damage from Mulligan this round.

Wulgar looks at the false Ragnar and tries to ascertain what kind of priest he would be, who his deity could be.
