Dodger is an unlockable passive Ability. Once acquired, the first shot fired at the trooper is automatically dodged. While it is a handy choice in most situations, it doesn't save one from the effects of Toxic Shells or Paralysing Shells at all. On top of that, weapons shooting 2 rounds at a time (like Dual Pistols) can still hit the target with one of the rounds, dealing half the usual Damage.
This skill has no effect on launchers.
This ability also works on fragmentation grenades.
