GOBLIN HORDE

Zenodur positions himself well behind his more melee-focussed friends and casts Armor of Agathys on himself, gaining 15 temporary HP and cause 15 points of cold damage for any water elemental that sneaks past the others.

Z's familiar in the meantime flies at the closer of the two and starts buzzing around and distracting it, i.e. providing the help action. So, first person to attack (ranged or melee) can roll with advantage.

As a free action, Zenodur telepathically communicates with the Elementals using his Awakened Mind telepathy: "What do you want? Why are you here?!" (this specifically only requires that they speak some language [Aquan, according to BR], but do not need to actually share Z's language)

Bow handbow in hands shoots of three quick shots at the elemental that just got distracted

Attack: 14 Damage: 22

Attack 2: 11 Damage: 25

BA Attack: 20 Damage: 20

Assuming at least one hits: 

(Whenever you damage a creature with your Crimson Rite feature, you can choose to sear an arcane brand of hemocraft magic into it. You always know the direction to the branded creature, and each time the branded creature deals damage to you or a creature you can see within 5 feet of you, the creature suffers 3 psychic damage.

Your brand lasts until you dismiss it, or you apply a brand to another creature.)

Randall:

Reacting after the assault by the water elementals, Randall focuses his efforts on the more damaged one, calling down holy flame on it and summoning a mace made of force to bludgeon it!

Attack: 21 Damage: 5 

And his fire burns brighter, doing 4 more damage on one of those rays that hits

Zenodur shrugs at the lack of response from the water elemental. His familiar uses the help action as usual, and he attacks it with Eldritch Blast.

Blast 1 Attack: 19 Damage: 12

Blast 2 Attack: 23 Damage: 12

Assuming the Elemental is still alive, he tries one more time to communicate telepathically "Cease your attack, and you may live!" (Z is trying to get one of their enemies to surrender and talk, so that they may find out why they and the villagers are being chased, and who is setting all these monsters on them. Given the rules of this communication, the Elemental definitely understands him and could respond).

(OOC: That's some good rolling there. Critical hit and max damage! Shame the second one missed) 

Bow seeing the water elemental coming into his space started holding his breath and just shoots his handbow up into, hopefully, his "head" to destroy the water elemental from the inside.

Attack 1: 8 Damage: 22

Attack 2: 13 Damage: 19

BA Attack: 18 Damage: 26

Randall:

Seeing his companions pulled into the elemental’s core and in danger of drowning, Randall prepares to cast a spell, just after he shudders from a firm slam made of solid water.  Finishing his casting of Water Walk, Randall smiles as the power of the spell quickly propels everyone inside the elemental to its surface.

He then commands the mace made of force to one again bludgeon the attacking elemental in the hopes of dispersing it soon.

Spiritual Weapon:  Attack: 28 Damage: 13

ooc: Now thats creative :)

Tempe lands on a mast nearby and throws a couple more sunbolts Attack: 26 Damage: 13  Attack: 8 Damage: 10

Attack: 9 Damage: 5 

OOC: sounds good to me.

(Yeah Rising upwards sounds good to me aswell. Nice move Randall^^)

Zenodor's saving throw: 4

I believe this counts as a melee attack? If so, the Water Elemental will take 15 cold damage from lvl3 Armor of Agathysand has its speed reduced by 20ft. (so, down to normal 10ft / swim 70) 

OOC: Very  creative and nice move Randall!

Petcan unleashes a 3rd level scorching ray on the elemental

Attack: 18 Damage: 4 

Attack: 22 Damage: 6

Tempe climbs down and bows "I have never seen such a display of power. That was amazing, all of you!"
