Baron Strucker's trait reads:

Hydra Sees All Each friendly characters [sic] possessing the HYDRA keyword or team ability may ignore one other friendly character possessing the HYDRA keyword or team ability for line of fire purposes once per round.

My question is in regard to the "once per round" aspect. Suppose I have two lines of fire that occur in the same action. For example, my Hydra character might be making a ranged attack and using two arrows (such as IC U-Elektra). Another example would be using one of those things that lets you (Red Skull, Baron Strucker, etc) poison from two squares away but only if you have line of fire (Orange Lantern, Toxic Burst feat).

Suppose that there is one Hydra character blocking two lines of fire. Can I ignore the character for both lines of fire? Would I have to ignore the character once for the first line of fire and again for the second line of fire, meaning I couldn't? Or since it's all the same action, does that count as only ignoring the character once?

Dual-targeting shouldn't come into play...you need to ignore a friendly character to establish a bead on two figures? Just fine.

If it's only 1 character blocking LoF, I'd assume it's okay. But if it's two characters blocking your dual-target attack, you wouldn't be able to ignore both.

Right?

That's right...dual/triple-targeting, just as long as it's only a SINGLE friendly character blocking your LOF, you're golden.

Would that "once per round" mean: game, turn or each round? I know in my area players that come in refer to this as one in the same. I'm assuming "ONCE" per round means only "ONCE" per game, correct?

No, generally a "round" is: Player 1 takes their actions, their turn ends, then Player 2 takes their actions, their turn ends.

In simple terms, at least.

"A HeroClix Core Rules game is broken down into a series of rounds. During a round, the first player takes the first turn. When the first player’s turn is complete, the player to the left takes a turn, and so on, clockwise around the table. Once all players have taken a turn, the round is complete and a new round begins."
(from the rulebook)

In the newest rule book WK has defined each term. We, as players, need to practice using the correct terms so rules remain clear.

Its on page 7 and the glossary:

ROUND: A measure of time during which all players take a single turn.

A Turn is when a player is on the offensive. Once all players have completed their turns, the current Round ends and the next Round begins.

So with the Strucker Trait, a Hydra figure could use Probability Control during the opponent's turn through a friendly figure provided they did not yet use the Trait to draw line of fire through the friendly Hydra figure already this Round.

I can just see how much fun this is going to be...

Player 2: You attacked Strucker and hit? Okay, I'm going to have Hydra Guy#1 ignore Hydra Guy #2 so that he can use theme team PC on Strucker.

Player 1: Sorry, Hydra Guy #1 already ignored a hydra guy for line of fire purposes on your turn, and two turns make up a round. You can only use this trait once per ROUND not turn.

Player 2: Yes, that's true, but a ROUND consists of the first player's turn followed by the second player's turn. When Hydra Guy #1 ignored line of fire on my turn, that was last round. The current round began during your turn. Thus, Hydra Guy #1 can in fact use Strucker's trait to ignore Hydra Guy #2 to use TTPC on Strucker.

Player 1: Oh, yeah, that's right. But if I had been player 2 and you were player 1, then you wouldn't be able to.

Player 2: Yeah, that's right. Simple, isn't it?

Unfortunately, confusion can abound because of the Tournament Rules document:

Tournament Procedure: Matches consist of one game each. Pairings in the first round of a standard Swiss-style HeroClix tournament are determined randomly. After the first round, the judge determines pairings by tournament standing, including tiebreakers (see Section 1.2.3); for example, the player with the best record faces the player with the second-best record, the player with the third-best record faces the player with the fourth-best record, and so on. The judge must take care to avoid any rematches during Swiss rounds, pairing players with the next lower rated player instead (and so on, until a match is found). Rematches are acceptable only once Swiss rounds have ended and championship rounds have begun (when championship rounds are used).

I do wish the word "round" didn't mean two completely different things in Heroclix, but you can usually tell which is meant from context. It's hard enough for me to remember that "round" doesn't mean "turn", but lots of experience with old-school D&D (where 1 turn = 10 rounds) helps.

Ah, I forgot the tournament terminology (now I understand how one could confuse game and round).

Not too sure this is correct. Player #2 would be dead wrong.

I don't see why it is wrong.

Round 1:

Player 1's turn. Stuff happens.

Player 2's turn. Stuff happens and the trait is used by character X.

Round 2:

Player 1's turn. Stuff happens and, since it is a new round, character X uses the trait again. Yep, even though he just uses it the previous turn. It is a new round, after all.

Player 2's turn. Stuff happens, character X wants to use the trait, but can't since it isn't a new round yet.

And so on...

Could you elaborate?

I was assuming that if the ability had been used on Round 1, then it could again be used on Round 2.

Would it be your position that if this ability had been used on Player 2's turn then it could be used again until Player 2's turn again? This would follow if "once per round" meant the same sort of thing as "once every 24 hours".

I was under the impression that "once per round" would have more a "once each day" quality (meaning once on Monday, once on Tuesday, etc, meaning that if it was used on Monday at 11:59 PM, it *could* be used on Tuesday at 12:01 AM) rather than a "once every 24 hours" quality (meaning if used at Monday 11:59 PM, it couldn't be used on Tuesday at 12:01 AM).

I believe SimonMoon is correct:

Round 1:
Player 1 - does something
Player 2 - Uses Strucker's trait

Round 2:
Player 1 - makes an attack, player 2 uses Strucker's trait for a TTPC
Player 2 - can't use Strucker's trait.

It might be a bit convoluted, but it works per how rounds are defined.
