pathfinder flamboyant arcana question Opportune Parry and Riposte

[martn]

Flamboyant Arcana (Ex)

A magus gains the derring-do and opportune parry and riposte deeds from the swashbuckler’s list of deeds.

The magus can spend only points from his arcane pool (not panache points) to use these deeds and any other deeds he gains from the deed arcana. He can’t use points from his arcane pool to use deeds from other classes or those gained by feats, nor can he regain points to his arcane pool as a swashbuckler would regain panache points.

Derring-Do (Ex): At 1st level, a magus can spend 1 panache point when she makes an Acrobatics, Climb, Escape Artist, Fly, Ride, or Swim check to roll 1d6 and add the result to the check. She can do this after she makes the check but before the result is revealed. If the result of the d6 roll is a natural 6, she rolls another 1d6 and adds it to the check. She can continue to do this as long as she rolls natural 6s, up to a number of times equal to her Dexterity modifier (minimum 1).

Opportune Parry and Riposte (Ex): At 1st level, when an opponent makes a melee attack against the magus, she can spend 1 panache point and expend a use of an attack of opportunity to attempt to parry that attack. The magus makes an attack roll as if she were making an attack of opportunity; for each size category the attacking creature is larger than the magus, the magus takes a –2 penalty on this roll. If her result is greater than the attacking creature’s result, the creature’s attack automatically misses. The magus must declare the use of this ability after the creature’s attack is announced, but before its attack roll is made. Upon performing a successful parry and if she has at least 1 panache point, the magus can as an immediate action make an attack against the creature whose attack she parried, provided that creature is within her reach.

MY question is about the last sentence and the requirement for 1 /arcana/panache point. Do i have to spend that 1point or do just need to have one left over. for example in derring-do it says i need to spend 1 point to get the effect of derring do but not so in the last sentence of opportune parry and riposte

[LordKailas]

The way I read it you just have to have one left over. You've already spent a point and an AoO to activate the ability. Seems kind of excessive to force you to spend another resource for the final effect.

I've never played a character with panache based abilities though, so I could be wrong on this.

[RAWmonger]

You don't need to spend the point. Same as the swashbuckler, so long as you have one point remaining you can perform the riposte as an immediate action.

The idea behind this for swashbucklers is that they have a couple different abilities that function as long as they have one point, so they always tend to keep themselves at at least one point, and then rely on hitting a crit or killing an enemy to refill their pool above 1 point, at which point they start using their panache-spending abilities again until they're back to 1 point. The only time you want to use that last panache point is if it's a guaranteed thing or if you're going to die if you don't.

This doesn't translate over as well for the magus arcana abilities, since you don't have such easy ways to refill your arcane points.

To circle back around to the answer: You do not need to spend an additional point to riposte after successfully parrying, you simply need to have at least 1 point remaining after spending a point to parry.
