I know that I've been trying to implement too many abilities with her and attempt to faze out the out-of-role effects for next time.
 * There is no source ability from any actual game - the concept of their character was based on RPGs, and the ability was basically "every turn, Chiharu increases her max health".
 * Chiharu can cast her Q without breaking stealth, so Daisy's presence only shows that she is nearby.
 * Chiharu is not meant to be completely unsightable either, just sneaking around the enemies.
 * All the enabler spells are not really meant to be stacked and/or contain CC. Chiharu's assassinating power only really comes later into a fight because without her 4 Scan stacks, she won't be bursting people down quite enough. Which makes her pattern a long period of vulnerability followed by a period of power - which is actually gated by her other cooldowns, W and E both have a 12-second cooldown, and that's late-game because W's cooldown is higher until maxed out.
