Surin

Bleed Stacks Everywhere

You might think Surin needs help applying Bleed, considering that her S1 only causes Bleed if the enemy is already Bleeding. However, since her S2 can apply up to 4 Bleed stacks at once (!) that last for 2 turns on a 3-turn cooldown, AND her S3 increases the duration of debuffs by an extra round on top of that, once Surin causes Bleed once, she's usually good for the rest of the fight.

100% Bleed Chance

While Surin's Bleed affliction rate is still subject to the Effectiveness vs Effect Resistance check, her base chance to apply Bleed on her S1 and S2 is 100%. This gives her a higher chance of applying Bleed than just about any other hero, and it also means she isn't as dependent on Effectiveness as most debuffers.

Very High DPS

Surin has high damage multipliers, decent Atk, great Spd, a lot of bonus damage from her endless Bleed stacks, and one hell of a nuke in her S3, which gains 25% extra damage for every stack of Bleed the target is suffering from. With a 3-turn cooldown on her S2 and a 4-turn cooldown on her S3 (after Skill Enhancement), her skills are even fairly spammable, resulting in a lot of damage over time.

Fast Hero + Speed Imprint

Surin is naturally one of the fastest characters in the game. She also has a Speed Devotion Aura that helps other members of her team move more quickly as well.

Takes Extra Turns

Every time Surin uses her S3, she gains 15% CR for every stack of Bleed on her target (capping at 75%). Considering how easy it is for Surin to keep Bleed stacks on her opponents, this often means Surin basically gives herself an extra turn with every S3. She can also Soulburn her S2 for a full extra turn, giving her a perfect setup chance for a maximum-strength S3 when needed.

Countered by Cleanse/ Immunity

Surin is almost unable to function in the current PvP environment. With so much full-cleanse and Immunity flying around, it's very difficult for her to keep her Bleeds running so she can capitalize on them. Unfortunately, this also comes back to bite her against bosses who can cleanse themselves, in particular Golem 11, which she would otherwise be excellent at fighting.

Has Nothing But Damage

This might be Surin's biggest flaw: she has no utility other than a 1-turn Attack Break on her S2 (which barely counts). When so many other heroes can bring enormous DPS to the table along with game-changing buffs or debuffs, Surin has trouble making a good case for herself.

Uses the Whole Debuff Bar (No, Really)

Did you know there was a limit to how many debuffs you could apply to one enemy? Rest assured that Surin will teach you this lesson. Especially if she's paired with other debuff units, Surin's Bleeds can overtake the entire debuff bar, leaving you no room to apply more important debuffs like Defense Break or Unhealable.
