> Assists have insurance (They persist even if the point gets hit)
Not so much with Kohaku. For example if Kohaku is on point and performs 4BC assist (Hisui pot throw), the throw will get canceled if Kohaku is hit before the pots become active. However, the long startup time actually can work in your favor if you're in Moon Drive because the entire startup becomes clash-active.
Kohaku specific:
> Arc drive is unblockable when charged
Also un-shieldable.
> Loses molotovs
Loses GROUND molotovs. Still retains air molotovs.
