The second bag contains 9 beans.

Bean roll: 73

Another fruit tree appears.  This one has 28 fruit.  Of these, 7 act as random potions, and 1 acts as a random poison.

"Let's hold onto these in case we need them.  I think the chuul is immune to poison, so maybe we can give it the fruit if it gets hurt."

Bean roll: 54

Yet another tree appears, this time with 25 fruit, including 7 that act as potions and 1 that acts as a poison.

Bean roll: 33

A second stone statue appears, this one resembling Spark.  It makes threats against her and describes her as a villain.

Bean roll: 72

Yet another campfire with blue flames appears.

Bean roll: 99

A pyramid comes out of the ground with a sarcophagus inside it.

"That thing looks dangerous.  We could go inside, but it would be very risky.  What do you think?"

“I’ve heard they bury immense treasure in these things! But perhaps whatever lays in there comes out?”

"I suspect it is full of trees and statues."

“We could wait here outside for them to come outside, or what you think?”

"If it does come out, it might be an easier fight.  Wait, something about this pyramid looks familiar.  Let me think about it..."

Spark's Arcana: 21

"You remember those mummies we fought?  The ones that cursed you?  I've heard that some of them live in pyramids like this one.  Only these mummies are more powerful, and can do magic.  And also turn into sand and move faster.  They are very dangerous, especially if we go into the pyramid.  But they are still rather flammable."

(OOC: A mummy lord would be a deadly encounter for us, at least three times over.)

“Flammable sounds good. I just need to get the spells through. Starting from a hiding place would help greatly. Perhaps, we can lure it out?”

“I can send Moni inside and let her fire at everything until she draws attention then she teleports out into our trap. I‘m not sure if mummy’s can be angry but if they do, that could do the trick.”

"I have seen a lot of dead things over the years and some of them can be really nasty.  But if you want to anger them, I have your back."

Rizo shrugs, "I still have a bone to pick with mummies." Then he sends Moni inside the Pyramid (close to the exit) to shoot fire bolts at everything until something moves. As soon as there is movement, she is to shoot once at that and then return quickly, either with a teleport or simply flying back. Rizo remains hidden from sight behind a curtain of white spraying, falling water.

Spark remains inside an illusionary rock, with Magic Stones and her rite prepared.

The chuul, in preparation for what is expected to be a difficult battle, eats a huge pile of fruit.  These include 10 that act as random potions.

Without any obvious way to choose what the random potions are, I will choose them from the magic item tables in Xanathar's, in the order in which they are listed: 12 17 26 17 4 16 4 11 16 22

The chuul gains the effect of the following potions:

Potion of Diminution, Potion of Invisibility, Potion of Superior Healing, Potion of Frost Giant Strength, Potion of Diminution, Potion of Resistance, Potion of Vitality, Potion of Healing, Potion of Cloud Giant Strength, Potion of Growth

It is also affected by three poisons, which do nothing because it is immune.

It gains a total of 30 health, becomes invisible, and shrinks to Medium, but with 27 strength.  It also gains resistance to a randomly chosen damage type: 1

The chuul is now at 82 health and resistant to necrotic damage.  It stands outside the pyramid's entrance, ready to murder a mummy.

Angered by Moni throwing fire around the pyramid, the mummy lord emerges from its sarcophagus.  Although it is aware of Moni's presence, Moni is ready and can take one turn as it is emerging, then we will proceed with initiative in its normal order.

Mummy Lord's starting HP: 87

Mummy Lord's initiative: 9

Spark's initiative: 19

Chuul's initiative: 20

Rizo hiding still behind his water fall, initiative: 15

Moni shoots a fire bolt at the mummy to make sure it knows who to follow, then moves outside the pyramid. (I think the mummy could already do legendary actions at the end of Moni’s turn, right? Or does it need to wait to have at least one turn itself? Never had to deal with legendary actions before…)

Attack: 13 Damage: 11 fire damage (already doubled)
