Hysilens Best Team Compositions & Character Synergies

Kafka is the absolute best Character to be played with Hysilens. Kafka is a DoT based Nihility Sub DPS that triggers DoT damage. Kafka acts as the driver for the entire DoT archetype by triggering DoT multiple additional times per turn and providing a 100% ATK to all allies with at least 75% Effect Hit Rate.

Black Swan is a very powerful DoT based Nihility DPS. Black Swan also has strong supportive debuffs since she reduces enemy DEF and increases enemies DMG taken during her Ultimate. Black Swan synergises extremely well with Hysilens because Hysilens extra DoTs cause Arcana to stack up faster which adds a lot of damage. Additionally, the DoT damage from Hysilens' Ultimate also stacks Arcana.

Cipher is a very fast Nihility Character that can generate a lot of Skill Points without costing any significant amount of DPS as her main debuffs automatically apply themselves without Cipher needing to act or use her Skill. The Skill Points are very valuable for Kafka as she is incredibly SP draining and ideally Hysilens wants to spend multiple Skill Points too. Cipher also provides her damage boosts via increased Damage Taken on the enemies, alongside a mechanic that stores damage to later be dealt as True DMG based on what your allies dealt to the enemies prior to Cipher using her Ultimate Yours Truly, Kitty Phantom Thief! which will reset the stored amount.

Silver Wolf is a Nihility support character that applies a very strong DEF Reduction debuff as well as a lot of All-Type RES reduction. With Hysilens 25% DEF reduction from Ultimate, 18% from the DoT Set, 45% from Silver Wolfs Ultimate and 12% from Silver Wolfs implanted bugs the enemy will have 100% Def Ignore/Reduced which is a 2.1x DMG increase in total. Silver Wolf will have to use a lot of Skill Points to have good uptime on Ultimate as she cannot use Tutorial mission as Kafka is ideally using it. With Silver Wolfs E1 this is significantly easier and less Skill Point negative.
Silver Wolf also can implant weaknesses so the enemy is always on Element which is another large increase in DMG as well as making it easier to break Weakness in Apocalyptic Shadow. Silver Wolf also does very high Toughness Damage herself.

Luka is a DoT based Nihility DPS that deals mainly Single Target damage. Luka's Ultimate also provides a DMG Taken increase on a single enemy. Luka can also cause Bleeds to deal damage whenever he uses his Enhanced Basic ATK which works nicely with Hysilens. Luka is also good in Apocalyptic Shadow as he is also Physical Based and deals decent Toughness Damage which may make breaking the boss faster.

Sampo is a DoT based Nihility DPS that applies Wind Shear to all targets with his Ultimate or slowly from his Skill Bounces. Sampos's Ultimate also provides a DoT DMG Taken increase on all targets. With at least Sampo's E4 his Skill will cause Wind Shear to instantly deal damage per hit of the Skill if there are at least 5 stacks on the enemy which works nicely with Hysilens adding a significant number of Ultimate DoT triggers. These will deal full DMG despite the very low multiplier for DoT on Sampos E4 because Hysilen's Ultimate DoT triggers do not scale with DoT effectiveness.

Ruan Mei is a strong Harmony support character that provides a significant team wide boost to DMG which is excellent in DoT teams that have multiple Characters dealing damage alongside 10% SPD which is nice to have. Ruan Mei's Ultimate provides All-Type RES PEN and causes enemies to delay their turn when recovering from Weakness Break. When they delay their turn like this they still take damage from all DoTs on them and then have their normal turn shortly after, effectively increasing the total damage they take from DoT effects. This does cause applied debuffs to expire faster as well which can hurt DoT uptime slightly. Ruan Mei is also especially excellent in Apocalyptic Shadow because she increases Weakness Break Efficiency for everyone on the team.

Robin is a highly versatile Harmony Support that offers significant buffs to DMG% and ATK to the entire team. Due to providing buffs to the entire team she is very well suited to buffing DoT teams that often have multiple relevant damage dealers. Robin's Ultimate will also Action Advance the entire team letting you deal significant upfront burst. Additionally, DoT teams almost always include Kafka who launches a large number of Follow-up ATKs to generate Robin Energy.

Tribbie is a highly versatile Harmony Support that provides All-Type RES Pen for allies and increased DMG Taken on enemies. Tribbie also does frequent AoE Follow-ups that makes applying Hysilens DoTs quickly and efficiently easier. Tribbie can also run the Dance! Dance! Dance! Lightcone to grant more turns for the entire team.

Huohuo is a powerful Harmony Sustain Character that buffs team ATK% with her Ultimate and generates energy. The Energy Generated causes more DoT triggers over a fight due to building Kafka's and Hysilens' Ultimates faster. Huohuo uses more Skill Points than other Sustain options and can be harder to use, especially in triple DoT teams where Skill Points are already in very high demand.

Gallagher is an extremely skill point positive Harmony Sustain Character. Gallagher hits very frequently which is good for applying Hysilens' DoTs quickly and his Ultimate is AoE and used frequently which can set up DoTs on multiple enemies. Gallagher can also use the Quid Pro Quo Lightcone to generate significant energy for everyone on the team which helps alleviate any energy issues that Hysilens has.

Hyacine is a powerful Remembrance sustain character that hits multiple times per turn and deals AoE damage. This makes applying Hysilens DoT quickly to all enemies very fast. Hyacine is not as Skill Point efficient as other Sustain Units which is not ideal for DoT teams but she is still a strong choice.

Aventurine is a skill point positive Preservation Sustain Character. Aventurine can run Trend of the Universal Market which adds another DoT for Hysilens' Ultimate which is a significant damage gain before E1. Aventurine also launches frequent Follow-up ATKs which helps to apply Hysilens' DoT effects quickly to more enemies.
