Overview
Her Skill is simply incredibly strong if you can get it going. 50% DMG/Acc is very high, and the reload reduction is nice too. The main issue is that Bunkers take a while to be generated for the back columns. For longer fights this is a complete non-issue, but for shorter ones there’s some significant RNG in where the first two Bunkers will spawn.
Bunkers are generated based on her own position and tile layout at the start of battle, last until the end of battle (or her being retreated) and cannot overlap. As such, if she starts on pos2, Bunkers will appear on pos2, 5 and 8 at the start of battle, with new Bunkers only being generated on pos1 and 4, no matter where you move her afterwards. This makes her position in the Echelon Formation quite important. Take note that “empty tile” in her Skill means a tile currently without a Bunker.
By default it will take ~35s for her to have Bunkers on every tile if she starts the battle on pos6.
The Mov buff is sadly multiplicative, but still quite nice.
