Kakania tries to kill Razor with Kindness (R1999 Roguelike, Difficulty 15)
Trying to weaponize Kakania's Heal Reflect was an interesting experience.
I already knew it was possible in certain Raids, but trying to make the strategy work in A Series of Dusks requires more than some specific characters.
Lots of equips are needed to increase the tankiness of your party, but the main artefacts needed to make this viable are ones that let you inflict extra Flinch stacks. Flinch increases Genesis damage taken, and you can see in the video Razor has about 150 stacks of this effect before he dies.
The main artefacts I used were the two slightly different Cicada Ring artefacts. One of them inflicts 4 Flinch stacks on all enemies, the other inflicts 10 Flinch stacks but on a random enemy. Both have different activation requirements that are annoying to fulfill. I basically need to spam Heal, which sounds easy until Balloon Party's Heal ranks up to a Counter and screws with the Incantation Syntony you're going for.
Another item that helps is Basil Honey. It gives the user Regen stacks whenever they use a Rank 2/3 Incantation. The more of these you have, the more often Kakania can activate her Heal Reflect when she acts, the problem is finding that many copies.
There's a whole bunch of other stuff I learned from this run:
-Self-damaging moves do make Kakania build empathy faster. This isn't relevant for regular modes, but it works here and I run Aid Nick Bottom specifically since he can drain HP faster than most other options (Aid Eternity, Semmelweis or Ezra).
-Balloon Party's Heal/Counter won't proc the Reflect if Kakania's HP is too high
-Eternity also doesn't seem to proc the Reflect consistently if Kakania is using her Ult at full HP.
-Dikke's Heal will actually proc the Reflect twice if healing at low HP.
While this strategy can be very fun if your artefact RNG is on point, this party is suuuuper boring to play if you can't find any of the artefacts you need. It's not even hard, it just takes forever to end encounters if you're not picking up Flinch inflicting artefacts. I strongly recommend playing this with a different Catalyst, maybe Symphony of Synergy since that lets you easily get Resonance Disk Drives that inflict Flinch at the start of fights.
