If you really like to start a Ballista Guide i suggest reading This

Its not mine but a very skilled Ballista Player By the Name of Abbadon of Fenrir (Credit goes to him), Altho it is very old and doesnt contain BLU COR or PUP and some items aswell, but this is a start for you tho.
You Receive Ballista Points Through out the Battle by doing the following:
* Scoring Petras
* Participating in Engaging an Enemy and actually fighting instead of the "Hit and Run" Stradegy. Yes it has been proven.
* Not Dieing and giving the opponent Gate Breech (Altho its been said if you die from Poison or any DoT effect, it wont count against your points, this has not been confirmed)
* Heal Heal Heal, Ballista is a Team sport, and i know millions of White Mages that have done thier job on keeping the team alive and score and make as much as 250 if they are elusive to the Enemy.
* Getting Kill shot doesnt give you any more points then the others around you, you just need to be around the person that died and the party member dealing the blow to get the Gate Breech (if your outside of party it wont affect you)
* Using Items that benefit you will increase your Ballista Points very slightly. (Estamated to 1 Point per item.)
