Official Move Approval IV

[Oleander]

I've already purchased Debuff, just forgot to add the prerequisits. The Iaido: First Strike can only be used once. It isn't particularly straining, it's just that the circumstances only allow it to be used once per encounter.
The Katana is not particularly tiring either, being it is his primary form of attack, not to mention the steeple of his combat capabilities. The damage is only assumed as high as it is due to Takezo's 5 ATK, which from what I understand is pretty decent. It also requires both hands, meaning he can't preform any supplementary actions with his offhand.
The bleeding aspect is simply due to the katana being a blade... and blades cut. It's a static effect, not a more strenuous variation. As mentioned, the damage is only mild by comparison to the actual attack.

Ah, those questions were for the second move, not the Katana. With the way you formatted that I assumed the first move was context and the second blurb was flavor text to introduce the Iaido. You’re good on the Katana...I'm familiar with how swords work.

For the Iaido, you’ll need to have some kind of downside beyond the single use. Per Omni, cooldowns/use restrictions on a single move aren’t actual downsides since you’re allowed to still use all of your other moves. If you don't want to do it based on stamina I'm open to other suggestions; that's just what most people do.

What about failure rate?

On top of the auto fail if the target has Foresight, if a Foe's TEC is greater, they can recognize the slight of hand, noticing the way he turns down his sheath in preperation for the strike. As such, they can easily side step the attack and negate it entirely.

Asside from that, I'm open to suggestions. It's no different than the average attack, except that it just adds an element of surprise for greater effect.
