If I'm using Boomerang or Ultron or someone with two or more attack arrows, can they perform multiple Energy Explosion attacks in one turn, reducing the damage down to one (and then raising it back up with enhance and SHIELD ability, heh-heh)?

You have it almost right. They can target multiple figs with a single attack and not make multiple attacks. Not only will they take additional damage from Enhancement and Shield but if the targets are adjacent they will take "splash" damage from the adjacent target as well.

OUCH!
So if I target two adjacent figures, they get hit via splash both times?

If so, this could be one of the most powerful attacks in the game!

I see the light bulb burning bright above your head!

But, yeah... most veteran players already have this tactic down.

If a character has 2 or more bolts, they can target 2 or more opposing characters with a single attack, having the damage dealt reduced to one click? Is that correct? And if so, can powers such as energy explosion and pulse wave be used against each target of this multi-attack?

Oh, and what is splash damage? Does it only apply to the damage dealt to adjacent figures of a character targeted by energy explosion?

Ohhh, my head hurts....

Yes, that's correct. One attack, multiple targets, 1 click. And yes, Energy Explosion may be used in a multiple-target attack like this. Pulse Wave cannot, however---it already hits all targets within half-range, so allowing multiple targets has no meaning.

Splash is the term for the damage of adjacency associated with Energy Explosion, yep.

Although, a ripple effect Pulse Wave would be pretty awesome!

One question that came up last tournament was, if you EE against two adjacent figures, how much does the guy behind them take?

A judge there said that each of the figures you target takes 1 + 1 splash =2, then the figure next to them takes 4.

I now fear Ultron..

Your judge played the targets right (it sounds like the targets are adjacent) but not the figures behind the targets. The figures behind the targets would only take "splash" damage. (They are not the targets of the EE.) So any given figure would take one point of damage for each target that is adjacent to. (Which in your case, it sounds like 2 adjacent targets so 2 points of damage.)

The reason that the targets took 2 was because of -- 1 from the attack itself and 1 from the splash from the adjacent target. (This also assumes that both targets were hit. If a target isn't hit, there is no splash.)

That's what we thought, but he said that since both targets took 2 damage, the figures behind them would get splashed for that amount from each.

Nah, as you can see the targets only took two because they were adjacent. One for being hit and one from splash.

Had the targets not been adjacent, each one would take one and the adjacent figures would each take one from splash.

A favorite is an adjacent figure in the middle.

TAT

Each T (for target) takes one while A (for adjacent) could take two clicks from splash.

or even better...
