The Vigil is an unusual Minmatar ship, serving both as a long range scout as well as an electronic warfare platform. It is fast and agile, allowing it to keep the distance needed to avoid enemy fire while making use of jammers or other electronic gadgets.
The Vigil is the Minmatar EWAR frigate. It has bonuses to target painting effectiveness and range.
Target painting can be situationally useful when damage-dealing ships need help to apply their damage to elusive targets. However, due to stacking penalties on target painters' effects, fleets of any size usually only need a few target-painting ships.
Tactics
Like other small and fragile electronic warfare ships, the Vigil is often best-served by "bouncing" away from the fight and back when targeted. Vigil pilots can fight while pre-aligned to a nearby celestial and warp out as soon as they are locked up or start taking damage, and then warp back in to continue applying their painters.
