When he shot the arrow it  just snapped after hitting a cave wall. It is now vahl's turn.

Vahl tries to shoot a zombie with an arrow.

Attack: 14 Damage: 11

You hit the zombie in the should knocking it's arm right off. Black gew purs out of it's arm but it keeps going. The wraith at the door you are all next to floats through cha' ,giving him opertunity attack, and places it's hand on bills now feathery chest and tries to suck the life out of him.

Bill Attack: 11 Damage: 20

Then make a con 14 check or loose 30 max hp if hit.

Cha' the wight in front of you slashes you with is sword. Attack: 19 Damage: 10  then it takes its sword in 2 hands and swings again at cha' Attack: 22 Damage: 12

Then it is demakos turn.

Since we are still all next to each other Damakos casts sumbeam at the vampire it needs to make a constitution saving throw or be blinded if it succeeds it is not blinded but it still take 8d8 radient damage also my hands are lit up brightly and the light coming of and the damage it took is actual sunlight. 34

So now the vampire cannot regenerate.

Also since it's in sunlight it takes 20 radient damage at the beginning of each of it's turns while on sunlight.

The light lasts a minute

Con  16 

Also I know what vampires are weak to. You don't need to clerify it with me. Anyway it will attack you Attack: claw 10 Damage: 9 bite Attack: 8 Damage: 9

I think the bite hits so you take 7 more damage to your max hp and some of its burns heal.

Both of the zombies go up to Vahl and attack her first zombie Attack: 7 Damage: 7

Second zombie Attack: 5 Damage: 7

The mumy will then attack bill Attack: 9 Damage: 14 then take another 10 necrotic damage and needs to make a dc 12 con check or get mummy rot. (Can't heal, and looses 10 max hp every 24 hours starting now.)

It is now cha's turn.

The attack doesn't hit Bilberry

Cast Call Lightning at a vampire 5th level: 18  Damage: 20

oppertunity attack vs wraith: I pull out my knives and swing attacking for 11 and doing 6 damage

If you do that you will hit everyone exept the ghost so you and everyone else need to make a, dex check? 

Vampire 12

Wraith 15

Zombies2 

Wight 16

You hit the wraith wit the oportunoty attack . What does the check need to be.

Dex: 17

OOC: That was a nat 20

I just realized i can't cast call lightning because i have to be able to create a storm cloud and there is not enough space to do so.  

Instead i am going to cast Conjure Animals at the 3rd level.  I am going to create 2 Dire wolves.

Assuming they live through this battle they will be with us for 1 hour.

I order them to attack the vampire
