Chasca / Iansan / Bennett / Vodyanitsa

# enjoygm lists Chasca / Bennett / Iansan / Vodyanitsa without a rotation.
# Rotation from the written Chasca / Iansan / Bennett / Furina team
# (teams/chasca-iansan-bennett-furina), which follows the KQM Iansan
# quick guide, with Vodyanitsa's skill in Furina's place, moved to the
# last swap before Chasca as she holds Thrilling Tales; she bursts when
# ready. Bennett's opening skill is cast only when ready: without
# Furina's actions between them, his closing skill (the guide's
# "(Bennett E)") leaves it on cooldown (9.5 s/min of waits otherwise).
# That team's guide rotation, Iansan / Chasca / Bennett / Furina:
#   Furina ED Q > Bennett EQ N1(1) > Iansan ECQ > Chasca E 4[C] (C/Q)(2) >
#   (Bennett E)(3)
#   1 reapplies Pyro if Furina vaporizes (C6 Bennett); 2 burst when
#   available, else hold the charged attack until she lands; 3 for his ER
# Chasca's combo in gcsim (skill, four aimed shots, then the burst or a
# last shot) is the one of the community config behind Chasca / Furina /
# Mavuika / Bennett (db.kqm.gg), which also ends with Bennett's skill.
# Iansan's burst restores Nightsoul points from the active character's
# movement, which gcsim counts only when the rotation reports it. The
# Iansan quick guide says Chasca can maintain Iansan's ATK buff uptime
# as long as she constantly moves during her aerial state, so every
# action reports movement at 9 m/s since the previous one: the lowest
# speed tried (6, 9, 12) above which the score stops rising, so her
# higher ATK buff stays up (design §5.4).
