ST-Atk is a junction that your characters can gain access to if they have Guardian Force that has the 
ST-Atk-J junction ability. There are no ST-Atk-Jx2 or ST-Atk-Jx4 abilities (like there are for ST-Def-J) because this ability grants your character’s physical attacks a chance to inflict a status on the enemy, and these physical attacks can’t hit with more than one status at the same time.
“ST-Atk signifies attacks with status change or which have status change added to them. After setting status change to an attack, the attack will change an enemy’s status. Most magic has a status change, such as Sleep, which causes the Sleep status.”
