Jouster

Jouster (Prerequisite:: Fighter Sub-class of ANY Knight or Paladin)

Jousting is a martial game between two horsemen wielding lances with blunted tips, often as part of a tournament. The primary aim was to replicate a clash of heavy calvary, with each participant trying hard to strike the opponent while riding towards him at high speed, breaking the lance on the opponent's shield or jousting armor if possible, or unhorsing him. The joust became an iconic characteristic of the knight. The participants experience close to three and a quarter times their body weight in G-forces when the lances collide with their armor.
