Varesa / Iansan / Furina / Xianyun

# KQM Iansan quick guide, Iansan / Varesa / Furina / Xianyun:

# Varesa's combo from the KQM Varesa quick guide, same team:
#   Varesa 2[ECP ECP (Q)] JP JP ECP (Q)
# Its gcsim form (ECP when her skill is ready, a jump plunge while
# Xianyun's airborne buff lasts, else CP; the 30-energy burst after a
# plunge out of Fiery Passion) is the one of the community config behind
# Varesa / Ineffa / Furina / Xianyun (db.kqm.gg).

# 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 Varesa easily keeps Iansan's Nightsoul points
# above 42 for the higher ATK buff, 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).
