Adding:

>>> U N N A M E D   L I M I T   B R E A K (https://www.youtube.com/watch?v=AOoKBzEiWMA)
• Description: Kiran channels glimmer into the battlefield itself, causing enchanted metal walls to erupt from it. For the duration of the limit break, Kiran can manipulate these walls, sending them around the battlefield to defend allies, or slam violently into enemies.
• Type: Active.
• Activation Time: Standard Action.
• Attack Range: 40' around Kiran.
• Attack Duration: Rounds equal to half character level (7 current total).
• Attack Damage: N/A.
• Additional Effects: When this limit break is activated, Kiran creates one wall per 4 HD he has (3 current) within 40' of himself. Each round during the LB, he may use a move action to create an additional wall within 40' of him, and/or a standard action to move a wall up to 40'. If a wall is moved to hit an enemy, it performs a Bull Rush maneuver using 10+HD+INT for the maneuver bonus. If successful, this Bull Rush deals an additional d8 bludgeoning damage per 4 HD (3d8 current).
Kiran and other allies adjacent to one of these walls gain cover against ranged attacks, and DR/- equal to 1/3 HD (DR4/- current). This DR stacks with DR granted by any other sources - including multiple adjacent walls.
Finally, when an ally adjacent to a wall is attacked, Kiran may spend an immediate action to shatter that wall and have it take half of that damage (after accounting for DR).
The walls are 5' thick, 10' long, and 10' tall.
Some bullshit about break DCs.
