Minty is paralyzed by the mummy lord's glare.  Rizo is frightened, but not paralyzed.

Not wanting to enter its own Insect Plague, the mummy lord opts to stay at range, first targeting the chuul with a Dreadful Glare, and then summoning a Spiritual Weapon to attack Rizo.

Chuul's Wisdom save: 6

Spiritual Weapon: Attack: 14 Damage: 6

The chuul is also paralyzed.

Minty cannot act because of the paralysis.

The mummy lord uses its lair action to learn the locations of nearby living creatures.

With her companions having trouble, Spark decides to use the Necklace of Fireballs.  She approaches just in front of the insect plague and throws a bead to the side and behind the mummy lord, so it hits the mummy lord but not any of her allies.

Fireball damage: 56

Mummy lord's save: 9

The fireball from the necklace incinerates the mummy lord.  Each party member receives another 5000 XP.

Rolling for treasure: 6

This mummy must not have been as rich as the last one, but the party still finds 184 gold pieces.

"So shall we plant the rest of the beans?"

After a minute of terror that the mummy lord would just return from the ashes and continue to haunt him, Rizo finally shakes off the magically induced fear. He heals himself (15 HP) and offers Minty to reapply an enchantment for one of his weapons (+2 for 1 hour, concentration). “Now, I’m ready for more mummies or whatever these beans throw at us.”

"That was terrifying -- literally." "Bless my bow and I am prepared to battle more mummies (or strange fruit).

Spark plants another bean.

Bean roll: 87

Another nest pops up, this one with 6 eggs.  Spark plants the last bean.

Bean roll: 5

The last bean erupts in a geyser: 3 3

It spouts berry juice into the air for 8 rounds.  Spark takes her waterskin and tries to catch some.

"Well, that's all the beans we have.  Anyone want these eggs?"

Rizo is interested in the eggs, “We have 9 of those eggs, right? That makes it three for each, unless someone doesn’t want them.” 

Rizo tries one of the eggs, breaks it carefully and slurps its content down.

con save: 19 DC 20 or 31 force damage

Rizo’s belly rumbles as if Tempus himself throws a fit inside. Bending over in pain, he returns the rotten egg to the cave floor from where it sprouted. “Can’t recommend them,” he adds after a short pause.

I'm not sure if this is an error with my tooltips but to me it looks like you rolled 1d4+3 for the beans, shouldn't it be 1d100?

It doesn't really matter, I really had a blast with this expedition and the bags of beans made it even greater. What a boost for our experience counter. I think Rizo gained 2 or 3 levels... but also almost died.

 That's weird.  Either I accidentally put the wrong input in, or the forum is acting up again.  Let's try again: 77

12 bright pink toads appear.

"What should we do with them? They seem harmless to me." Rizo says as he picks up one of them.

"Rizo could try eating one."

“Ha ha! No, I don’t eat living animals. Actually, I prefer fruits over everything else.”

The pink toad transforms.  As usual, the Bag of Beans provides no guidance as to what it transforms into, so I will choose a random Large or smaller creature from the Basic Rules with CR between 1 and 7: 82
