Hit the Deck/J.E. Sawyer's Fallout RPG

Hit the Deck is a perk in Fallout Tactics, Fallout:New Vegas and J.E. Sawyer's Fallout Role-Playing Game.

Fallout Tactics
You react very quickly to the word "incoming!". This perk halves the damage from area attacks and splash damage.

Fallout: New Vegas
Your extensive familiarity with Explosives allows you to ignore a portion of their damage. Your Damage Threshold is increased by 25 against any and all Explosives — including even your own.

Bugs

 * There is a display error with this perk. The +25DT will be shown in your PIP-Boy menu whenever you have an explosives-category weapon equipped. However, the added DT will correctly only apply against attacks from explosives-category weapons, regardless of what you have equipped.

J.E. Sawyer's Fallout Role-Playing Game
You react very quickly to the word "incoming". When hit by damage from explosions or sprays, you are considered to be an additional 2 hexes away from the origin for purposes of determining damage.
