Erlan

is my understanding, I can take two attack’s, both with advantage?

I continue working on bringing down the larger of the two. I swipe my dagger against the jackalwere before bringing the dagger back for a second slice. 

Attack 1: 16 Advantage: 14 Damage: 7

Attack 2: 21 Advantage: 10 Damage: 5

If I have enough movement, I rush toward Violet. 

No, you can take ONE attack with advantage, because you have used one already in previous turn. Pick either one of the attacks you've just rolled. The first does more damage, the second does less, but will draw attention of the jackalwere to you, Crassus will have yet another attack of opportunity (he would have 2 against jack1 - one when it misses with biting plus one when the jackalwere turns to you. Plus, his own action). The choice is yours.

The second attack works for me 

The jackalwere does not hit Crassus this time, so it's going to take an attack of opportunity from him.

Attack:21

Damage: 12

Crassus, you have 2 attacks of opportunity, actually (I know it's not strictly by the book, but it makes sense. The jack1 passes by you, provoking first attack then is attacked by Erlan, turns to him, while you are still near, realy to slash it again.

That's firstly. Secondly, you wait for Pict to do his turn, then roll for your attack, but the attacks of opportunity can be made out of turn.

The second Attack misses with a 9

Pict notices Violet as she slumps to the ground, asleep, and turns to her quickly. "Come now, lass, no time for sleep just yet, still got work to do" And he will nudge her awake using his action.

Violet, you can now take your action before the start of the next turn. On next turn, you're after Crassus. You are also immune to this spell for the next 24 hours.

Snapping out of her trance Violet instinctively throws a Fire Bolt at the Jackalwere that gazed at her.

Crassus is going to  keep swinging away at Jackalwere 1, since he's been wearing away at that one for a while now.

Attack: 23

Damage: 7

Crassus will then spend a bonus action taking a Second Wind and regain 6 hit points

Okay, let's calculate HP before it gets too messy.

Jackalwere1 is left with 3 HP (good work ;))

Jackalwere2 has 21 HP.

I've added HP on your character pages so we could keep track on them more conveniently. Violet is next to attack, then the jacks, then it's Picts and Erlans turn.

Crassus is there a reason you don't use the forum's way of rolling dice? I don't mind, not really, just curious.

Part of it is a personal superstition that physical dice roll better than computer dice, part of it is I just enjoy the actual act of simply rolling it.

Violets hand begins to crackle with lightning. Suddenly a translucent coating covers the lightning and a bolt of energy powered by the trapped lightning within shoots towards the badly hurt jackalwere.

I believe you’re correct. Then I’m up 

The fight continues. Despite the beating they took, jackalweres are nowhere near the point of surrender.

Jackalwere1 (3HP) launches at Erlan. His AC is 14.

Attack roll: 7

Damage roll: 4

The second one continues to pester the sorceress, apparently believing her the greatest threat with all the mystical blasts she's bee throwing around.

Jackarwere2 (27 HP) tries to take a bite out of Violet. Let's see, her AC is 12

Attack roll: 17

Damage roll: 7

Enraged jackalweres are turning sloppy, it would seem. Both attack miss drastically.

Erlan

seeing as jackalwere 1 seems a lot worse for the wear, I rush toward it and take a stab with my dagger. 

Attack: 18 Damage:6
