Time for some enlightenment.

How do dodge cost increasing seishin interact with multihit attacks? Say the following:
Mai Suzaku - 50 damage x 3, 10 EN / atk

If someone casts Concentrate, Sure Hit, or Snipe Attack, how much would each hit of the attack cost a say, Ninja Senshi (DC 10, no mods from unit) to dodge? Please elaborate for each case.

How will the three above spells, as well as other TDC increasing effects, work with (X) attacks?

What is the advantage of taking Snipe Attack over Sure Hit?

Thanks for reading.

Ok, say you cast Concentrate with that attack. A Ninja without dodge cost modifiers would have to dodge the attack all three times for 15 PCs each time.

If you cast Sure Hit without dodge cost modifiers, they would have to dodge the attack all three times for 20 PCs each time.

Both of those spells stacks. So if you were to cast both Concentrate and Sure hit, that Ninja would have to dodge all three hits for 25 PCs.

Now, let's say that Ninja is in something fairly dodgy, such as a standard Valkyrie in Fighter mode, giving them a -10 to their dodge cost. Now their dodge cost is 10 - 10, which is effectivly 0. However we have the minimum dodge cost rule, so despite them technically having a dodge cost of 0, they still have to pay at least 5 PCs to dodge. However, if you were to cast Concentrate, this would merely bring their dodge cost up to 5, making it effectivly useless. Sure hit could bring their dodge up to the standard 10, which is a little better, but not the best effect. Enter Snipe Attack.

Snipe Attack basically nulls all other dodge cost modifiers, and then adds 10 on top of that. So using the previous example of the Ninja Valkyrie, if you were to cast Snipe Attack, the Valkyrie's inherent -10 dodge cost would be nulled, and they would be forced to dodge for 20 PCs each time. This works both ways however, and any Dodge Cost modifiers on your attacks, such as High Performance Targeter are also nulled.

In regards to (X) attacks: Concentrate will add +5 Target's Dodge Cost to all of the parts of an (X). Sure Hit and Snipe Attack will only affect the first hit.

I hope that helped.

Concentrate affect the entire first attack phase, so with that attack would have 3 hits of +5 DC each, costing a total (10 + 5 = 15 x3) = 45 PCs to dodge. Snipe Attack and Sure Hit however, only affect the first attack, not first attack phase, meaning a total of (10 + 10 = 20, 10 x2) = 40 PCs to dodge everything. That's why Snipe Attack and Sure Hit tend to be saved for really big nasty single hits.
Now, the difference between Sure Hit and Snipe Attack is that Snipe nulls all other DC mods on the attack. So for someone with no DC mods, there's no difference. Where the value of Snipe Attack comes in is if your opponnent has numerous DC mods helping him. If that Ninja Senshi was in an Aile Strike (Inherent -5 DC) and then brought with a Tesla Drive (Item -5 DC), with Sure Hit, he'd be dodging for 10 (10 - 5 - 5 + 10), but with Snipe Attack, because it negates those DC mods, he'd be dodging for 20. (10 - 5 - 5 + 10). Of course, this works both ways. If you had a Newtype (Class +5 Target DC), with a High Preformance Targeter (Item +5 Target DC), he'd have +10 Target DC, and if the enemy Ninja had no DC mods, he'd doge for 20 (10 + 5 + 5)
With Sure Hit, he'd make that poor Ninja dodge for 30 (10 + 5 + 5 + 10), but with Snipe, he'd only have to dodge for 20 again (10 + 5 + 5 + 10). And if that Newtype happened to be in Turn A (Inherent +5 Target DC), Snipe Attack would actually make an unmodded opponent dodge for less than without it. 25 (10 + 5 + 5 + 5) vs. 20 (10 + 5 + 5 + 5 + 10)

Ok, so the concentrate seishin affects all parts of a multi-hit, but you 2 have differing opinions on Sure Hit and Snipe Attack.

Mechalomaniac: Sure Hit + 3-hit = +10 TDC, 3 times
Yanbetari: Sure Hit + 3-hit = TDC +10, +0, +0

Mecha: Snipe Attack + 3-hit = +10 DC, 3 times
Yan: Snipe Attack + 3-hit = +10, +0, +0

Ummm. Er? Ah?!
