"I could with my cape but this was problematic last I used it so i do not wish to try it unless necessary," Silas replies. 

"I do not have any means magical or otherwise to get through the bars, I would need assistance." Mal says as she gets prepared for another fight. "Grenk are you equally as dangerous from range as you are from melee? If so I can possibly take the brunt of the fight for the next battle. If anything I can just draws the creatures attention and then dodge its attack while the rest of you bring it down." Mal offers. "Otherwise a short rest would probably not hurt us."

"I am good with a bow.  Prefer it really, just with this fancy magic sword I could really pump out damage.  That is if I could hit. Also, if we be facing a caster or some sort, I'm better up in their business.  That said, I'm worn down."  His face lights up a little.  "I think I still have those posion arrows from the snake people.  I can tag out this round then."

"Well if you are going to stay at range, I could make good use of that flaming sword and I promise to hand it back you when we are done." Mal grins sweetly and offers out her hand innocently.

"It takes an hour to bond with it fir the fire but other than that its a well balanced sword." Grenk says as he puts out the flame and hands it to him pommel first.

Grenk will take potion for 9 hp

"Leave the sword aside then," Silas states before looking at the cabinets, "If anyone think they can handle another battle, I think the clock or the ghouls may be a battle for us in our state. With the undead, I can try to turn them. We can rest afterwards or that is the path I believe we should follow,"

Grenk moves further back and sheaves his sword puts his shield away and pulls out his bow arrows and poison arrows.  

(Silas, you don't seem to have a choice in what cabinet to open, it seems they need to be opened in order, and the witch one is next.) 

Glancing around, the group seems to be ready for the next battle.  Mal steps forward and swings open the witch door.  The door opens above the caldera of an active volcano. Shards of black rock float above the molten magma. Perched atop one shard are two man-sized creatures with insectoid features and four arms apiece. They both glance up at the doorway, then abruptly vanish...and appear within the room at two locations. 

(Roll init obviously.) 

Demon init : 4

If you go before them, feel free to roll an attack. 

Sicke will cast Cure Wounds at 3rd level also on Grenk. 19 HP  “I didn’t realize you had taken so many hits in that fight?”

(DM, how big is this room? Would it fit a Giant Ice snake like before?)

(It's 40 feet across roughly, though pentagon, so yes, which you can still summon prior to initiative / the door being opened)

Initiative: 17

"Well then," Silas position his spirutal weapon and give them a smack before just blasting one nearest to Mal with a Guiding Bolt at 1st level.

Spiritual Weapon Attack: 22 Damage: 9

Guiding Bolt Attack: 24 Damage: 13 +10 to hit for 24. 

Will use Channel Divinity to give Guiding Bolt a +10 to hit.

Silas' spiritual glove swings down but just misses one of the demon insect creatures who is clutching a trident. His guiding bolt strikes true though, making the thing glow. 

Grenk initiative 6

Grenk grips the bow in his left hand arrow at the ready.  When the creatures appear he lets loose an arrow and then another at the creatures.

Two attacks at the one that didn't get the guiding bolt.

Attack: 12 Damage: 11 + 11 poison damage

Attack: 15 Damage: 9 + 3 poison damage

Both arrows clatter off of the chitin shell of the creature flying away without effect. 

Badger Initiative: 7

Badger sees Grenk's arrows bounce off the creature and thinks This won't do at all. The gnome holds his crystal orb up to his face, looking through it at the refracted distorted image of Grenk. He concentrates on the image until it transforms into the most fearsome creature he has ever beheld, then speaks the words and performs the action that will transform the goliath into the creature...

Polymorph Grenk into a Tyrannosaurus Rex. I think no saving throw if he is willing.

[OOC: SO the sword would take an hour to attune to, what actually does it mean to attune to it, can I just be holding it and using it for an hour, or do I need to sit with it across my lap and focus on it? Currently I would be using it in one of my hands replacing one of my scimitars. Also do I get the +1 without it being attuned?]

Initiative: 12

Mal swears as the things appear in the room and she moves up to one of them and then notices it glows. A grin sweeping across her face as she starts to rain blows down upon the creature.

Flametongue: Attack: 26 Damage: 8 Sneak Attack: 7

Scimitar: Attack: 14 Damage: 7

[OOC. Just noticed it is not a +1 sword, silly me.]

(the glow only gives advantage on the next attack, but in this case it didn't make a difference) 

Mal leaps forward, laying into the glowing Mezzeloth with a fiercesome blow that sends a gout of black blood spraying across the floor.  It cries out in pain and anger. The second blow strikes as well, but the non-magical blade seems to leave only a shallow slice across its hide. 

(Grenk, please make a wisdom saving throw vs. polymorph)

(Attunement requires a short rest spent focused on the object: https://www.dndbeyond.com/sources/basic-rules/magic-items#Attunement ) 

Grenk wis save 20

Grenk feels a wave of magic wash over him, trying to twist his form.  He sets his jaw and his mind to overcome it.  With that he shrugs it off and keeps his true form.

Badger, to your surprise Grenk shrugs off your magic with a furrow, seemingly unwilling to be transformed.....you have a brief feeling of loss for what could have been....

(Ok, just waiting on Sickle then.)

[OOC: Ahh, thank you, was being lazy with not looking it up.  I was not sure if my attack would benefit from the Guiding Bolt or not, but like you said, being an Assassin Rogue if I go before the bad guys I get advantage on the attack, they are not auto-crits unless they are also surprised.)
