first of all u were wrong u cant edit stats for spear in 6600-6699.xml cos that are stats for spear and not for its SA unless u want to just add smthing
you need to search in skill stat section.. cos SA is a passive skill

<skill id="3591" levels="1" name="Special Ability: Infinity Spear">

Spd., and Accuracy, and gives a bonus to damage inflicted on an enemy during PvP. It reflects debuffs targeted upon the character back upon the enemy. It enables the character to attack multiple enemies.
