Necromancer's Delusion-Homebrew

(I knew it!)

Aryn will shudder slightly as the lightning bolt rocks the hallway and glance back at the damage then rush north and stab at the center guard with her swords.  If the first hit puts him down she'll attack the one to the northeast.  "We've got company behind us as well.  I'll take care of this.  Jinara go help them take out those damn mages." she says to the group.

Attack:  (fighting spirit and elven accuracy)  14   11  (2nd attack)   26    Damage:   5   21    (2nd)    6    10

Dex save:   26     (Can I assume I saw Zinmaer get hit in the face with flame when he opened the door?)

"Owwww" Gaelin says out loud as he rushes east towards the door and will stop at the doorway against the back wall so as not to block it and throw 3 bolts of Eldritch Blast at the mage if I can see him. 

If I don't know there's a mage in there Gaelin will throw 3 bolts at the west guard to the north as he makes his way towards the west door.

Attack:   18      27      26    Damage:   8   8   7

As Zinmaer spins away from the mage Mucor charges past him, a cloud of spores slam into the mage choking the life from the body as Mucor brings down his staff with a loud crack.  The mage's eyes bulge as the staff caves in the top of his skull and blood begins to drip from his nose.  The lifeless corpse slumps to the floor in a heap.  Across the hallway Aryn rushes forward and uses her momentum to jab her flaming sword through the chest of the first guard.  She twirls as the guard's body falls to the floor slashing the shoulder of the northeastern guard and drops of blood now fall from his elbow.  Gaelin, hearing Aryn's instructions to the group rushes east towards the doorway where he saw Zinmaer dodge two blasts of flame only to get hit by a third and sees the second mage within a large apothecary room.  He points his staff and three greenish black bolts of energy fly out slamming into the mage's body cracking ribs.   The mage hunkers over from the impacts but regains himself smiling menacingly as a bit of blood seeps from his mouth.

Jinara!

map:

Jinara will come down adjacent to Gaelin. He will poke his head around the door, while pulling out his wand, and send a myriad of darts at the mage (3 charges for 5 darts). Then he will lean away from the door opening.

DMG 15

Jinara will use his bonus to convert 1 first level spell slot for 2 sorcery points.

The darts of magical energy explode from the wand like firework then align one behind the other, each impacting the mage in the sternum.  The last punches through the back of the mage's robe and the bloodied mage falls to the floor dead and a pool of blood begins to form by the corpse.  The two guards draw their swords and swing wildly at Aryn.

Zinmaer!

(Good call on that Aryn!)

Zinmaer would see Jinara and Gaelin sending in various spells into the western most room. He would hear swords clashing behind him that most certainly must be Aryn. He looks to Mucor and says, "Let's keep pushing forward." 

Zin would open the east door and move in to attack if he sees any enemies. (After opening the door what does he see?)

Mucor would nod to Zin and tear open the northern door if there were not lots of enemies within the Easter door.

Zinmaer opens the door to a third mage and two hell hound ready to strike.  The hounds breathe fire and the mage throws a small chunk of ice towards Zinmaer that hits him in the shoulder and immediately explodes into hundreds of needle-like shards.

Zinmaer and Mucor make two Dex Saves  DC 15 or take 24  fire damage, half on success and DC 17 or take   14  ice damage

Zinmaer you take 5 ice damage

mucor DeX saves! 14 21

Zinmaer Dex Saves

17

28

Zinmaer's agility will allow him to use Evasion and only take half damage on the failed dexterity saves.

After taking the hits he would brush it off quickly and move in to the eastern hound and strike him twice with his quarterstaff before taking the dodge bonus action (Ki Point spent).

Attack: 25 Damage: 12

Attack: 14 Damage: 12

Zinmaer's first blow impacts and digs a couple inches into the flesh of the beast but it recovers and sidesteps out of the way of the second attack.

Aryn, Gaelin & Mucor!

map:

Mucor would swing his staff down hard at the closest dog as the spores around him surround the hell hound in the center of the room and the cultist on the far side of the room. As he swings his staff, a swarm of insects will erupt from the staff as he casts Insect Plague and fills the room with a swarm of biting and stinging bugs. 

Staff attack against dog on the right Attack: 26 Damage: 9 plus 8 poison
Reaction spores against left dog : Con 16 or take 20 necrotic (half on success)
Bonus action spore toss against cultist : Con 16 or take 11 necrotic (half on success)
Second action because of haste : cast Insect Plague cON 16 or take 20 piercing damage, half on success.

Aryn will clinch her swords tighter as two of the guard's sword attacks cut into her flesh and will return the favor in kind attacking each once.  

Attack:  (East)   14    (West)   19     Damage: (E)  6    10     (W)   6    9

(@Aryn: Do you normally only get one sword attack?)

(one with action and one with bonus action currently)

Gaelin will head east and open the door to the north, if there are any enemies within he will throw Eldritch Blast bolts their way if not he will dash back around towards Aryn.

Attack:   23  19  10   Damage:  2     7     5   

Con saves:    8     11   9   8   4

Mucor rushes into the room swing his staff that cracks against the hound's head and breaks the jaw as he throws spores that choke the other hound and cultist before slamming his staff into the ground.  The gem in his staff glows and flashes as a swarm of insects explode into the room and gnaw away at everything living.  (Including Mucor and Zinamer make DC 16 Con saves or take 22 damage, half on success!) The hounds crumple to the ground and turn to embers while the mage yells in pain but remains standing and glares at Mucor through the swarm.

Aryn slashes low and disembowels the eastern guard who clutches at his organs that spill out on the floor before expiring in a bloodied heap.  her second strike hits the guard in the side and cuts deep before stopping on a rib.  The guard flinches in pain but remains upright.  Gaelin rushes east and opens the door to reveal an empty room that seems to be someone's quarters before rushing back up the hallway to assist Aryn.

Jinara!

map: 

(@Aryn: You are hasted. You get another attack if you want it.)

Jinara will move forward 20 ft in to gain line of sight on the one guard and cast Frostbite. (DC17 CON save. If FAIL it takes 8 and has disadvantage on its next attack) After letting loose the cantrip, Jinara would then back up 5 ft and watch the doors in this hallway vigilantly. He will spend his bonus action to convert another 1st level spell slot for 2 more sorcery points.

(I don't know why but I read your post about hasting me as hasting Zinmaer and Mucor.  Xtra if you're good with it I'm posting additional attack below.)

Aryn fueled by rage, and Jinara's spell makes another wide swing at the guard.

Attack:  13    Damage:   8    9
