....With talking about duels and kata, was re-reading the chapter.
One thing jumps out at me:
Earth Stance
QuoteWhen other characters make Attack action checks and Scheme action checks that target you, they cannot spend * to inflict critical strikes or conditions on you.
Sounds simple.
Coiling Serpent Style:
Quote
*+: Choose one weapon a target has readied; that weapon cannot be used for Attack actions. This effect persists until the end of your next turn.
**+: One target of your action per ** spent this way becomes Immobilized.
I can't inflict Immobilized, because it's a condition, but I can trap your weapon, because whilst it's a persistant effect, it's not a condition. Earth Stance used to say "or persistant effects" but this seems to have been removed.
Spinning Blades Style:
Quote*+: You must spend * equal to your target’s Vigilance to activate this technique. You use your second readied weapon against one target of your action, inflicting physical damage equal to its base damage. If that target is Dazed, increase this damage by your ranks in the skill you used for the check
Definitely fine; it's causing damage. Some rules lawyers in the beta tried to claim damage as a persistant effect, but it was pointed out that a persistant effect is defined in the rules as something saying "this effect persists until [trigger]"
Breath of Wind Style
QuoteAir *+: One target of your action must resist with a TN 3 Fitness check (Earth 4, Fire 1) or suffer the Disoriented condition and fatigue equal to their shortfall. Increase the TN of the check to resist by 1 per * spent this way.
Crashing Wave Style
QuoteWater *+: One target of your action must resist with a TN 3 Fitness check (Earth 1, Fire 4) or suffer the Bleeding condition and fatigue equal to their shortfall. Increase the TN of the check to resist by 1 per * spent this way.
These two surprised me. They are spending * to inflict conditions - albeit with a check to resist - but it is implicitely implied they work against Earth stance because a variant TN is listed (granted your odds aren't good with crashing water, but that's not the point).
