Kinetic Cover how many walls can I put up in a turn.

[Half Orc Tengu]

This is the description.

Element(s) aether, earth, or water; Type utility (Sp); Level 1; Burn 0

You call up elemental matter to defend yourself and your allies from attacks. As a standard action, you can select one face of a square within 30 feet of you and move elemental matter to block that face, providing total cover from that direction. The face you select must be supported by the ground, and the kinetic cover cannot support more than 5 pounds of weight. Water, ice, and telekinetic force are translucent, but earth, metal, mud, and the like are opaque and block line of sight. A creature who strikes the cover can easily destroy it. Regardless of its composition, the cover has hardness 0, AC 5, and 2 hit points per kineticist level you possess. You can have a number of kinetic covers in existence equal to your Constitution modifier + 1/2 your kineticist level.

I interpret the selection of a face of a square to indicate placement of the wall. You can't make an entire square a block of ice but you can encase a square. It does not refer to how many walls you can raise at a time. Because it is not referred to you can raise your limit and I use my walls to encase range fighters and place wall in front of characters with low health to prevent a full round of attack.

I have one DM who agrees and one who does not.

The one that disagrees says that the wording 'selecting one face" means that I can only put up one wall at a time. I haven't seen anything written on it and would like a call from a creator.

[N. Jolly]

From the way I interpret it (and since it's a standard action) I'm assuming you can only raise one wall at once.

[Mark Seifter]

I agree with N. Jolly. It clearly states that you select one face as a standard action, like the other GM said.

[N. Jolly]

I believe as a workaround to this, if your GM allows you take monstrous feats, at 11th level you could take quicken spell-like ability (kinetic cover) seeing as it's considered a 1st level spell, thus qualifying for it, and then quicken a second barrier (which should be all you need) up to 3 times per day.

This should provide you with enough defense to avoid getting hammered, since two walls up is a lot harder to get around.

[Paulicus]

Seems pretty simple to me, one wall. I can't even see the other interpretation.

[Ravingdork]

It clearly states that you select one face as a standard action. However, if you put all your walls up in a straight line, rather than try to box someone in like the OP said, then it is still "one face."

Unfortunately, it also goes on to say, "one face of a square" which seems to indicate that N. Jolly, Mark, and Paulicus are correct.

[Alderic]

One. Unless you have a way to take more than one standard action in a turn, or reduce the time it takes to use a wild talelent.
