Was hoping I wouldn't miss anything, but Smart Steer actually got one extra very important change, giving it a damage increase based on combo recovery.
Note that the "damage_rate" mentioned only applies to the Smart Steer, not anything else.
UNI2 1.41 saw a pretty significant number of system changes, some of which may seem a little unintuitive in terms of implementation.
As such, I hope this video can shed some light on what changed and how.
