Wall of Revealing light

[malawifan]

Player A has Gravekeepers spear soldier and Necrovalley and attacks Player B when activates Wall of revealing light and pays 2000, so that ends the attack. On player B's next turn he draws a nothing card and ends. Player A then goes and attacks on his turn. Does player B pay another 2000 or not?
Does paying one time prevent attacks (<2000) for as long as it is on the field or is it for each turn?
Secondly if player A on the second turn adds Axe of Despair to power up to 3000 how many life points would player B have to pay to stop (if you dont pay each turn) -- 1000 more or would B have to pay the entire 3000.

 

[Dlanaan]

The payment for Wall of Revealing Light is only made once. As long as it remains on the field, monsters with an ATK less than or equal to the amount paid cannot attack. If the ATK of a monster increases, you cannot increase the payment for that Wall of Revealing Light. You would have to flip up a new Wall of Revealing Light and pay 3000.
