Prerequisites: Point Blank Shot, Mobility, Dodge
Suggested for: Melee-range pairs, switch hitters, ranged Cavaliers or Inquisitors.
Benefits: Whenever you make a single attack or full attack against an enemy with cover because of an ally standing between you, the obstructing player can, as an immediate action go prone. If nothing else grants the enemy cover, enemy gains no bonuses from cover. The act of falling prone from this feat does not provoke attacks of opportunity, but getting up from prone as a move action on the prone allies turn does as normal.
Normal: When an ally obstructs your view of an enemy, they cannot take any action to correct this, granting the enemy cover.
Mostly flavor for the purpose of recreating those iconic scenes, but also a way of helping out players that absolutely insist they must stand directly in front of your ranged character at all times and you really need to hit the enemy.
I think you've posted in the wrong forum. You are probably looking for the RPG homebrew forum. This is the card game forum. I am sure a moderator will be along shortly to get you back to where you need to go.
But I was really excited when I saw the title of your thread. How about playing a bunch of PACG and seeing if you can come up with a version for the card game? Sounds like a investment worth making.
