ICD: CD:
[Passive]: Grants self +3 Pigeonwings upon the start of the battle. When an allied unit has received a stat-decreasing debuff, increase that ally's rate of fire by ($pass_value)% for 4 seconds. This effect cannot stack with itself. This boost does not trigger other passive effects, and cannot take effect on the same unit within 3 seconds. When C-93 receives debuffs, activate passive effect for self and grant self +1 additional Pigeonwing, up to a maximum of 6 Pigeonwings can be stocked. [Active]: Increase all allies' damage by ($dam_value)% for ($duration) seconds and consumes all currently stocked Pigeonwings. For each Pigeonwing consumed, increases an ally's rate of fire by ($pass_value)%, stacking up to 2 times max. This skill prioritises unaffected allies with the highest current DPS and can stack with Passive skill effect. Once skill expires, grants self +3 Pigeonwings.
With the introduction of C-93, Girls' Frontline skill descriptions have reached lengths never before thought possible and are now giving even the most verbose MTG cards a run for their money. Fortunately, it's not nearly as complicated as it may appear at first glance.
So what does "properly supported" mean? C-93's passive will proc whenever your units are debuffed. There are some fairly reliable ways to debuff yourself (excluding debuffs that are very debilitating or those that on dolls who don't benefit from C-93's RoF buffs like AUG):
C-93's full potential is easy to bring out with either Anna Graem or Px4 Storm - both affect the entire team and the debuffs largely don't matter or are easy to counteract. While you can theoretically use her with M4A1Mod or IWS2000, this isn't necessarily the best idea since there are other dolls that provide better support than C-93 in that type of "double jupiter" team.
Sure, you can use C-93 to offset the Parachute Fairy penalty slightly since they do count as debuffs. You're still going to feel the debuffs though.
You don't really need to know this to teambuild her, but since you asked:
The 24% Damage and 60% Accuracy buff is only rivaled by Px4 Storm and gives two universally great offensive stats.
While C-93's buffs are fairly conditional, if everything aligns she can buff your DPS by at least 18% damage and ~26% RoF.
Debuffs affecting your own team are necessary for C-93 to reach maximum potential, and they are not always easy to come by.
C-93's tile buff layout forces her to stand on Tile 1 and severely limits teambuilding options as it makes position 4 buffers unable to effectively function in most cases.
The initial cooldown of only 5 seconds is offset by the fact that C-93 has to channel her skill anyway, so the RoF buffs will be somewhat delayed compared to the Damage buff.
