Translocation Meter or LOCK meter is a special ability seen on some bosses. Enemies with this special ability can wound the player for massive damage.
At the beginning the meter will be seen as [ ]. As the battle goes on the boss will attempt to LOCK onto you, which is indicated by the increment of no. of letters inside the meter. If the boss LOCK onto the player meter will be displayed as [!!!!] and on the next turn a missile will be launched at the player dealing half of your max HP and leaving him/her wounded.
If you Reposition or Run, the LOCK meter will be diminished, allowing you to stay safe through out the battle without getting struck by a missile on your face. While fighting bosses with this special ability it is a good idea to reposition more often during the battle.
