If you are struggling with Heroic Mode, here is what you need to know. The mode puts 2 relevant debuffs on your dolls:

Data Erosion
>Your dolls takes 15% of their max HP as damage at the end of their turn.
>If they end their turn without being within 2 tiles of an ally they take another 20% max HP damage on top of that.
>The damage cannot be mitigated.

You pIay around this by just ending your doll's turn within 2 tiles of an ally and by bringing a healer. It's that simple.

>Disconnection
>Your dolls get this debuff at the start of every turn.
>It reduces their attack by 80% until they perform a single target damage active attack.
>i.e. their skill 0 basic attack, or any single target attack.

Disconnection is the big one you need to pay attention to. To play around this, you need dolls that have the following:
>Support Attacks
>Counter Attacks
>Interception
>Extra Action that can follow up on a single target initial attack

See pic related for some doll recommendations and how to use them on this mode. The tl;dr is you should use a V1 Makiatto and spam her ult + S1 as usual. If you don't have one, check your support list, sort by ICE and CE and then grab a whales V6 Makiatto. She will single handedly carry this entire mode.
