"Ewww, is THAT the Lord?  I don't think I can help that!"

Dorno enchants a few more stones from his pocket and thumps the zombie on the forehead with one of them.

Magic Stone attack: 19

Bludgeoning damage: 5

The zombie tries to hold itself together: 23 but it fails, and falls to the ground.  You are now out of combat.

Does the cave go further in?

The cave does go further, yes.

Medicine: 19  - Does Alexana know if she had contracted anything contagious?
Investigation: 18 - Does Alexana find anything of interest in the zombie body?

"Anyone know about zombies?  Any experts here who can take a look at my wound, and tell me if I've caught something from his hit?" Alexana asks the group.

. . .
After they resolve the health check and search the body, Alexana will continue to search for traps or any signs of enemies as she goes deeper into the cave.

Perception: 15
Investigation: 21

(ooc: I don't know which of these to use for the search.)

There were no signs of any plague or disease on the zombie, and your wound is just a plain old bruise.  As you continue into the cave, you find a 10-foot high ledge in your path, with two zombies standing on top of it.  Roll initiative!

(Anyone who rolls stealth could be hidden.)

Stealth: 15

Initiative: 15

Aria lets out an "Ugh!" and cleaned the zombie ichor off her blade. As they traveled further into the cave, they spotted two more undead and the purple-haired bard swore "Beshaba's tits!"

Initiative: 12

Initiative:16

Stealth: 18

Alexana will attempt to shoot an arrow at one on her initiative.

attack: 19

damage:4

(Going to bed soon so I'll post my move too.)

Thresher backs away from the ledge, so the zombies will not drop on her, and pulls out one of her javelins to chuck at them.

Attack: 16 Damage:7

Zombie initiative: -1

No one is hidden.

(In the future, stealth won’t count unless rolled before initiative, so keep that in mind.)

Both zombies will drop their boxes of rocks on Aria (10 damage) and Dorno (9 damage).  Make a DC 12 Dex saving throw to negate the damage.  They will then both drop down, with one taking (5) and and the other taking (1) bludgeoning damage.

Dorno looks at the fallen zombie as if he is a bit freaked out by it, but moves on, following the others.  "Hello, Mr Rock Lord, are you ok?" he says, but mostly quietly and timidly as he is scared of this place.

Initiative: 9

Dex Save: 12

Dorno is scared enough that he gets a bit too eager and runs right up behind Aria in an attempt not to be left behind.  He almost pays for it with a box of rocks to the head but steps aside, watching Aria get hit.  "Hey, we just want to help the sick man!"  He begins tossing magically charmed stones at the zombies once again.

Magic stone attack: 10

Damage: 9

(The zombies are actually right in front of you.  They jumped down from the ledge, so if you still use a range attack you'd have disadvantage and provoke an AoO.)

Hmmm, ok, well since Dorno somehow got himself into the thick of it, I'll simply have him disengage after narrowly dodging the rocks and move to a safer location for a caster, ideally back in the direction they came so that he knows there aren't any dangers (traps, holes to fall in, etc.) there.

(Sounds good.  Aria.)

Aria attempted to cast Faerie Fire once again.

save: Dex 13

Alexana draws her short sword and attacks a zombie - to hit: 22; damage: 6

Thresher will move up, take out her great axe and slash at the zombie on the floor.(The zombies are still prone so we should have advantage on melee right?)

Attack: 18 Damage: 14

(The zombies were never prone, they landed standing.)

Dex saves: 18, 14

Alexana, you would have advantage (and thus sneak attack).

(Thresher, the faerie fire would give you advantage anyways.)

(Okay I thought they just toppled over the ledge. No difference in the attack roll then.)

Thresher misses and grits her teeth in frustration, letting out a audible growl.
