The Wildemount Irregulars (2020)

That hits.  I assume you also move the Echo so that you stay within range of it.

Giant 2 moves forward to attack Silent, chasing him down as he runs for the prisoner:

Attack: 15 Damage: 19
Attack: 24 Damage: 11

Giant 1 attacks Balassar:

Attack: 9 Damage: 13
Attack: 28 Damage: 28

They each get one hit in, and you're beginning to look rather bruised.  Corrected for Alton's Bane - no attacks hit.

Round Three
Alton
Prisoner
Balassar
Giant 3
Silent
Giants 1 and 2

Alton is up.

(OOC: Don't forget to subtract the 1d4 from the giant's attacks from the bane spell.)

"I don't think their listening Silent!" Alton shouts at Silent as he darts behind Balasaar and tags him on the back of the leg, "Toughen up big guy. This is going to be one of those tough fights, but no one can beat Balasaar 'Tarrasque' Silverstone!" Alton says, as he casts cure wounds and gives Balasaar a bit of inspiration before moving back closer to Silent and the horses.

Movement: Moves 10 feet to behind Balasaar, then another 10 feet straight back 
Action: Casts cure wounds at 2nd level on Balasaar for 6 healing
Bonus Action: Gives Balasaar bardic inspiration, for 10 minutes, Balasaar can add 1d6 to one ability check, attack roll, or saving throw.

Oops. Okay, 4 for the attack on Silent, and 4 for Balasaar.

Yep, they both miss.  So Balasaar and Silent took no damage from those attacks.

The prisoner appears to do nothing.

Balasaar is up.

Balasaar attacks Giant 3, cutting his scimitar along the creature's long forearm.

Attack: 17 Damage: 14

The Hill Giant retaliates, striking back at the dragonborn:

Attack: 18 Damage: 23
Attack: 18 Damage: 23

The club strikes twice against Balasaar's shield, producing a dent that will need some smithing to remove.  But Balasaar is unhurt.

Silent is up.  You hold the motionless prisoner in your hands, and his eyes now begin to glow fierce red.  He does not seem to be attempting to speak though.

Silent looks back at Balassar holding back the two giants, then makes up his mind and plunges his greatsword into the prisoner's skeletal chest. The Echo brandishes its sword at Giant Three and jumps around a bit. 

(OOC: I'm assuming the prisoner is either considered prone or restrained or both so I'm going to make the attack roll with advantage - let me know if that's not the case)

Attack 18 Damage: 16      

The magical greatsword sinks deep into the prisoner's chest, and he screams against the gag, and then keeps screaming as the sword seems to ignite his body, burning away clothes and the gag, so that the last moments of his scream escape and fill the air before being cut short as his throat and face are engulfed.  You drop the body involuntarily as the magical fire consumes it - it is not hot, but has the effect of an inferno, reducing the body to ash.

At the same time, the three giants drop to the ground and lie unmoving.  And then the sounds and motion of battle is replaced by sudden stillness and quiet.

Combat is over, and you are out of initiative.  From past the horses, you see a movement in the tall grass; a wolf slowly gets to his feet but makes no move to approach.

Silent thunks his blade into the soil and leans on it, catching his breath. Bastard had a built-in self destruct plan. Wizards. Tricksy blighters. 

After a minute or two, Silent will cautiously approach one of the fallen giants and try to check if it's breathing. (in case it's needed, Medicine 15 )

They are all three still breathing.  It's not clear to Silent when or if they will wake, but they are neither dead nor undead.

Silent looks to Alton and Balassar and gestures at the giants. Seems like they're all still alive, just napping. Do we wanna try getting information outta them when they wake up? Or should we take this chance to remove their heads from their shoulders? 

Balassar just shakes his head "No need to end it if they are back to normal."

Silent nods. You're our giant expert - maybe you'll be able to get some information out of 'em, figure out what that wizard was doing. 

Silent will sit down beside giant 2 but makes no moves to wake it up, instead keeping a hand on his greatsword in case the giants start attacking again once they wake. 

Silent, you wait for an hour.  The giants show no signs of waking. You can continue to wait, or do something else if you wish?

What are Balasaar and Alton doing during this time?  The horses don't need much attention, but Ghost seems reluctant to get near.

Alton looks between Balasaar and Silent, “I think that was the right call. If that thing was doing the red eye stuff I would hate to think what would happen to those in Bladegarden.” Whilethey are waiting for the giants to wake up, Alton will try to see if he can get Ghost to come closer with using some treats.

Make an Animal Handling check.

[skill]Animal Handlin[/spell]: 5 

Balassar just sits sharpening his weapon "Hopefully they still aren't trying to kill us when they wake up."

After the hour, Silent stands up. Right, who wants to do the honours of giving one of 'em a good wakeup slap? Silent looks at Balassar. I volunteer you, mate, since at least you can tell 'em good morning in their lingo before they starting swinging fists. 

Alton, it takes some time but Ghost does slowly pad over to you and allow you to touch him.  He seems nervous of the giants and the dead prisoner, though.

Alton scratches Ghost behind the ears, "Who's the best boy of the Tarrasque Pack and protects the horses? That's right, you are." Alton looks back at Silent and Balasaar, "Might be a good idea to just wake one of them up."
