Item of the Week: Deployable Pavise

I've always been a huge fan of the Genoese Crossbowman style, using a huge Siege Crossbow, while taking cover behind a Pavise. Since I've toyed around a PC concept based on that style, lately, a Fighter specialized in Archery, I wanted to polish my Deployable Pavise idea and make it somewhat official for my Campaigns.

When Wielding the Deployable Pavise in combat, you have the following effects:

During your turn, if Wielding the Deployable Pavise, you can do "Use an Item" Combat Action to Deploy the Deployable Pavise anywhere in a 5' radius around you, for the following effects:

• You lose all Wielding effects from the Deployable Pavise.
• The Pavise acts as Three-Quarter Cover (as per rule).
• Large and smaller Creatures consider the Deployable Pavise as Impassable Terrain. 
• Huge and bigger Creatures ignore the Deployable Pavise and can Knock it down as part of their Move Action if they enter the same square.
• Any Creature within 5' of the Deployable Pavise can do "Use an Item" Combat Action to Re-Deploy it around (5' radius), Wield it or Knock it down.
