Hysilens 
Nihility Styxia, the coastal city of intoxication and dreams, where echoes of old songs still drift among the waves. Helektra, Daughter of the Sea, Chrysos Heir who cleanses the Ocean's Coreflame, dispels the murky undercurrents and orchestrates a banquet of revelry for the heroes beyond the sky. The show must go on. Even if hope is as fragile as bubbles, the waves will keep surging forward.

Hysilens Best Teams
Free-to-play DoT Team
For a free-to-play team, you can pair Hysilens with Serval since the latter can apply the Shock DoT. Asta is a great free-to-play Support for her ATK and SPD buffs.
Premium DoT Team
This Hysilens team has her paired with Kafka. Both of them can help deal damage by applying DoTs and triggering them respectively. Ruan Mei is the best Support here since she can delay the enemy's Weakness Break recovery, allowing them to receive more DoTs. Huohuo is the best Sustain for this team since she can buff the party's ATK and restore their energy.
Triple DoT Team
You can also use Hysilens on a team with two other DoT units. A third DoT unit can provide extra damage and help Kafka trigger more DoTs with her kit. Black Swan works best here for her Arcana mechanics and the DEF reduction she applies on enemies.
Skills
Deals Physical DMG equal to #1[i]% of Hysilens's ATK to one designated enemy.

Hysilens deploys a Zone that reduces enemy targets' ATK by #6[f1]% and DEF by #3[f1]%, and deals Physical DMG equal to #1[i]% of Hysilens's ATK to all enemies. For every 1 instance of DoT taken by an enemy target within the Zone, Hysilens deals Physical DoT equal to #4[f1]% of her ATK to them. This damage triggers at the start of each turn or after one attack by an ally target, up to #5[i] time(s). And it cannot repeatedly trigger this effect. The Zone lasts for #2[i] turn(s) and this duration decreases by 1 at the start of this unit's every turn. When Hysilens gets knocked down, the Zone will also be dispelled.
An ally will be incapacitated once their HP is reduced to 0.
When an ally target attacks, there is a #1[i]% base chance for Hysilens to inflict the hit enemy target with one of the following states: Wind Shear, Bleed, Burn, or Shock. Priority is given to inflicting a different state. While in the Wind Shear/Burn/Shock state, at the start of each turn, the enemy target takes Wind/Fire/Lightning DoT equal to #2[f1]% of Hysilens's ATK for #5[i] turn(s). While in the Bleed state, at the start of each turn, the enemy target takes Physical DoT equal to #3[f1]% of their Max HP, up to #4[f1]% of Hysilens's ATK, lasting for #5[i] turn(s).
The base chance of applying debuffs to targets hit. The final probability is affected by the attacker's Effect Hit Rate and enemy targets' Effect RES.
After using Technique, creates a Special Dimension that lasts for #1[i] seconds and automatically moves forward. Enemies within the Special Dimension enter the "Soulstruck" state. "Soulstruck" enemies will not attack ally targets and will follow the dimension while it persists. After entering combat with "Soulstruck" enemies, there is a #2[i]% base chance to inflict each enemy target with #3[i] of the following states: Wind Shear/Bleed/Burn/Shock, all of which are equivalent to those provided by Hysilens's Talent effect. Only 1 Dimension Effect created by allies can exist at the same time.
