Darius growled as Merron's blow landed. Then he smiled at him. "The wizard used some cheap illusions to avoid getting hit. But you... should be more fun!"

He swung his blade, feinting an attack before spinning and thrusting to attempt the real strike, then quickly followed up with the rapier from his other hand, angled to force the artificer back if possible.

ACTION: Rapier attack to Merron - Attack: 23, Damage: 11
BONUS: 2nd Rapier attack to Merron - Attack: 25, Damage: 17 - uses the Pushing Attack maneuver
 - If it hits, Merron takes 6 extra damage and must make a STR Saving Throw (DC 13) or be pushed back to I-13 (@DM: does he hit the familiar?)
REACTIONS (for DM) -

Same as before, Darius will swing at the first person to (1) provoke an Opportunity Attack, (2) run into melee with him, or (3) make a melee attack on him and miss. Add the Maneuver damage for situations 2 & 3:

Rapier - Attack: 21, Damage: 8, Extra Maneuver Damage: 6

 

Finished!

Apologies for the horrendous formatting - on mobile. 

Nova sends a demonic whisper to his Imp, commanding it to use the Use an Object action to pour a healing potion down his fallen teammate’s throat. He then approaches (L7), hopefully drowning Apium and his ally in darkness, with the additional measure of providing his weakened ally some more protection. 

He reaches out, attempting to finish the job - again - at the cleric. 

Eldritch Blast: 24 dealing 6 damage. Crit damage: 8

(( Second Roll for Darius' first attack, to incl. disadvantage - 21 ))

Strength save for Pushing Attack: 16

Edit: concentration check for heroism: 9

death save: 1

 Darius with twin weapons a flashing twice, missed the first strike thanks to the alert mechanized dragon at Merron's side. So in the follow-up, struck even harder, nearly pushing the dragonborn back.

Nova bids impy to go off reviving the fallen half-drow. But before it can leave the reach of the severely injured dragonborn, a vindictive strike cuts the fiend down. Nevertheless, Apium quite literally never sees what hits him, and is soon  in a crumpled heap onto of Senin as Nova carries on past the pair, enshrouding both in Darkness..
(Now any may see spoiler here)

Sennin breathing eases, but he's not out of the woods yet...

Team(2) is up!

Key: '=' High wall (8ft.), '-' Low wall (2ft.), 'Ω' Boulder (5ft.), '€' Tree, '%' Door, '.' Turf, 'A-Z' Contestants, '?' Darkness, 

(Stepping over the short walls is difficult and will cost 5 extra feet of movement without a DC 10 Athletics or Acrobatics check. Attempting this check and failing will cause the character to fall prone.)

Arena 1: Stony Field(Round 3-Cont.)

Contestants:

Merron and Tin maneuver around Darius. Tin takes another force-empowered rend attack against Darius while Merron unleashes a blast of lightning into the center of the Darkness.

Movement: Merron to J-10, Tin to J-9

Action: Breath weapon is a 5 by 30-foot line towards L-7. DC 12 dexterity saving throw, 5 lightning damage on a failure/half as much on a success

Bonus Action: command Tin to attack Darius. To hit: 11, 4 force damage.

Reactions are same as before, Tin uses Deflect Attack if an attack targets Merron. Merron's opportunity attack (if applicable):

(( Darius' DEX Saving Throw: <removed>

Also, if Tin triggers an Opportunity Attack from Darius, I've already rolled it in my previous post's spoiler (don't add the extra damage.) ))

The pirate takes a bit of lightning damage, but manages to dodge most of the breath weapon while also evading Tin's attack.

(OOC: @RodTheBard; I don't think the lightning was targeted at Darius, it was aimed at Nova... and Merron and Tin just moved around Darius (staying within melee) in order to be within range for the breath weapon. But ClickFRN can clarify if he meant something else.)

Fenkas first telepathically communicates with Syldorn and has him fly up and out of the area of darkness to hover over Darius and prepare to distract Darius when the next attack targets him. Fenkas then sprints out of his corner and charges closer to the shroud of darkness in the center of the field. Knowing what is in the center of the field, he whispers a quiet prayer to Correlon and casts a spell on the fringe of the darkness attempting to put the darkness covered enemy to sleep. He will then run to Apium's unconscious body, and use a free action to grab the Wand of Magic Missiles from his unconscious body and sprint back to the edge of the map.

(OOC: @RodTheBard; I don't think the lightning was targeted at Darius, it was aimed at Nova... and Merron and Tin just moved around Darius (staying within melee) in order to be within range for the breath weapon. But ClickFRN can clarify if he meant something else.)

That is correct, the lightning was aimed into the darkness and Tin and Merron just moved to the other side of Darius, which does not provoke Op. Attacks

(( OOC: Thanks for the correction, my mistake on the direction of the blast. Darius is sitting at I-11 though... moving from J-12 to J-9 moves Tin from melee to ten feet way. ))

Death save: 6

Merron and his mecha companion reposition to lay down the punishment. But whereas the latter fails to get past the ex-pirates defenses, a weak but still dangerous breath of lightning is unleashed upon the center mass of the darkness, catching Nova.

Fenkas changes strategies, and in a burst of speed not only gets in position to catch Nova in a wave of wave of Lethargy, knocking him unconscious. Then its back to the game of keep away with Senin's wand in absconded with it, before racing back to his original position.

Apium breathing starts to grow shallower...

As Darius now stands conscious but alone on the field, the faint hissing grows louder before a black mist begins to finally pour out of the ports opened up in the staging areas, filling the area in its deadly embrace.

(@Nova: Need a Dex Save(DC 12) for 1/2 of 5 Lightning Damage.)

Team(1) is up!

Arena 1: Stony Field(Round 4)

Contestants:

Dex save: 5

Darkness is additionally down.

"What the--are you ignoring me?!" growled Darius as he lashed out at Merron, swinging a bit more vigorously than before.

(OOC: Darius took a hit earlier in post #362, he's down to 20 HP)

ACTION: Rapier attack to Merron (w/ disadvantage) - Attack: 10, Damage: 8
BONUS: 2nd Rapier attack to Merron - Attack: 18, Damage: 9 - again uses the Pushing Attack maneuver
 - If it hits, Merron takes 5 extra damage and must make a STR Saving Throw (DC 13) or be pushed back to K-9
REACTIONS (for DM) -

Again, Darius will swing at the first person to (1) provoke an Opportunity Attack, (2) run into melee with him, or (3) make a melee attack on him and miss. Add the Maneuver damage for situations 2 & 3:

Rapier - Attack: 7, Damage: 9, Extra Maneuver Damage: 1

 

Finished!

Sennin Death save: 6

Darius tries not only to avenge the fallen, but his own wounded pride in being ignored. Alas, the dragon's defenses only further to throw him so much off his game, that the follow-up strike is easily deflected off Merron's Shield.

Nova continues to snore away...

Sennin lets out a bloody cough as his condition slowly worsens...

Team(2) is up!

Arena 1: Stony Field(Round 4-Cont.)

Contestants:

Merron and Tin will attack in tandem, aided by Syldron above.

Action: Merron attacks Darius, with advantage because of Syldorn distracting Darius. To hit: 24, 11 Slashing Damage

Bonus Action: Command Tin to attack, to hit: 10, 10 force damage

Reactions: Tin will impose disadvantage on the first attack against Merron, Merron will make an opportunity attack if possible:

Fenkas once again runs from his hiding space in the corner of the map, out to the center of the fray and seeing that Sennin is still down from Apium's attack, Nova is snoring loudly from Fenkas's spell, and Darius is looking injured from some of Merron's attacks, Fenkas will look at the wand in his hand and shrug. "Well, let's give 'em a taste of their own medicine." He runs up to the low wall in the center of the arena to get a clear shot, and points the wand at Darius before releasing every last bit of magic stored in the wand towards Darius. Meanwhile, he has Syldorn continue to harass the fighter from the skies.

 Death Save: 8
