Order to simultaneously triggered reactions?

[Danceofmasks]

I'm person B.
Trigger is someone from either side starts shooting, and person A and B are gonna shoot each other.

now, I know person A is a cleric, so if we trade shots, he'll just heal himself.

I want to lose the roll-off if possible, so he shoots me first, then I shoot him.
Now my initiative is before his, so on the next round, I shoot him again and he falls.

No... if the Cleric acts before you with his readied action, he'll be higher in the Initiative Order than you are. So next turn, he'll act before you do.

Alright, let's break that down a bit...(Edit: This isn't actually how it works, see my post below).

B readies an action to shoot A when A shoots
A is about to shoot
B shoots
A shoots
B's turn again

How do you get two shots in a row? (That said, I see the point in readying an action to fire against someone who can heal themselves...well, I kinda do. If all the do is heal then they won't fire at you). If you want two shots without him healing, that's possible (maybe, but he could drink a potion). It is still better for you to win the initiative, however.

Because the trigger isn't when A shoots.
The trigger is when someone shoots, which is neither A or B.

 

[Danceofmasks]

Actually, when I think of it, readying to shoot A works just as well.
'cos ready is a reaction, not an interrupt, so A shoots, then B shoots, then B's initiative gets set before A, so B gets to shoot first next round.

Right. But this is how it breaks down.

Player A has readied an action to shoot Player B the moment anyone fires a shot.

Player B has readied an action to shoot Player A the moment anyone fires a shot.

Player C fires a shot.

Player A wins the roll. He shoots Player B. His action resolved, he is placed in the Initiative order directly before the trigger (which is Player C).

The Initiative order is now:
Player A
Player C

Player B now shoots Player A, in response to Player C's shot. His action resolved, he is placed in Initiative order directly before the trigger (which is Player C).

The Initiative order is now:
Player A
Player B
Player C

Player B cannot fire at Player A a second time before Player A acts, unless someone else grants Player B the ability to attack.

Oh, I guess it does work just like that. I just looked over the rules. Kind of odd.

B readies to fire when A shoots.
A shoots
B shoots (and B's initiative is just before A)
B shoots
A's turn

It seems strange, but I like it. It gives you an advantage if you know what the enemy will do. That said, it is still better to win the initiative. The sooner you ready the action, the better.

Oh, one note: You can't have your action readied for when "anyone" shoots. You have to specify a particular target.

 

[Danceofmasks]

Aha .. so Player B is actually better off if he uses a different trigger, such as when Player A shoots?

How about a little different scenario.

Let's say a ranger is walking (carefully) down the middle of a 15' wide hallway. Two invisible creatures--say goblins--are on opposite sides of the hallway, each with a readied action to swing as soon as someone enters a threatened square.

After the ranger get's hit by the first goblin attack, he uses his Fox's Cunning (an immediate reaction Power) to shift back one square and fire a RBA at the one that hit him.

The question is, does the other goblin get a chance to swing at him?

 

[Ardulac]

What about in melee, when a goblin moves a square, provoking OAs from 2 characters at once?
I'm guessing goblin tactics shift kicks in last (if there's a miss), but what about those OAs?

Since this question hasn't been addressed yet, I figure I should point out that you can't take immediate actions on your own turn. So the goblin doesn't get to use his tactics against an OA. It's much more interesting for monsters that can interupt to move away as they can't use that to avoid being threatened.
