Sorry if this has already been discussed, but what happens when my opponent shoots at a figure of mine that happens to be next to my wing guard, thus giving my opponent a strain? Meaning, when does that character suffer the strain damage? Say my opponent's deck has been drained completely (no CC in deck or in hand) and therefore is unable to discard to avoid the damage from strain. If that shooter only had 1 hp left, would he die before his shot impacted my character?

The strain is suffered when the ability is triggered, which is the declare target step of the attack. If the strain is taken as damage and if it defeats the attacker, the attack aborts before rolling the dice. In the campaign, if a hero attacker gets wounded, it also ends the activation.

This is the case for all strain effects? Meaning, the person suffering the strain, say he was being attacked by a trando within range 3 and therefore suffering a strain, will need to resolve that strain before dice are rolled?

Yes. All strain-giving abilities are immediate (unless specified otherwise). Relentless also happens just before the dice are rolled, and is considered strain/damage happening outside of the attack. If the strain from relentless defeats a target, the attack aborts (unless it's a hero becoming wounded).

(Also, if a hero recovers strain by spending an unused and unevaded surge during an attack, the strain is recovered in the spend surges step.)

Appreciate it.

Outside of the attack ? The attack aborts ? Does it mean it's not counted as an attack and I can attack someone else instead ? Or that attack is spent but doesn't go through all the steps ?

You spent the action for the attack already (and used abilities out of that). Aborted does not mean cancelled.

Because there no longer is a defender (or attacker), you simply can't get through the roll attack and defense dice step.

But an aborted attack means no "after an attack resolves" abilities can be triggered, because the attack did not reach step 7 of the attack resolution.

There are also other ways the attack can become incomplete. For example the figure may gain movement points and move out of line of sight. Unless the card (or rulesheet) says otherwise, it also means the attack is aborted.

Ok really interesting ! It didn't happen yet during one of my games but I am prepared now

In the campaign, if a hero gets wounded, it also ends the activation.

What makes you say that?

P. 10 of the Rules Reference Guide (under "Defeated"): "If a figure is defeated during its activation, its activation immediately ends."

Oh, sorry, I was confused. I thought this discussion was about Relentless.

This started with about Keep the Peace (Wing Guard), I just mentioned Relentless as another strain-giving ability which is immediately resolved.

If a hero gets wounded during his own activation (for example due to Bleeding or Keep the Peace), the activation ends even if there were movement points or actions left. Getting wounded from Keep the Peace would in addition abort the attack, but Bleeding gives the strain only after the attack, so the attack would be finished first. (Then you could argue whether the Attack action finishes after step 7 of the attack or after the abilities triggering from when attack has been resolved have been performed. I would argue the action end comes after those, because the Attack action fully encompasses performing an attack .)
