Yufine

One-Shot Potential

Yufine's claim to fame mostly revolves around her S3, specifically how easily she can one-shot a key enemy target with it. Her S3 does more damage to an opponent who has buffs, and buffs are a very common tool in PvP, which gives Yufine crazy damage potential in PvP. She is also able to provide her own Defense Break (with her S1) and Attack Up buff (with her S2). On top of all that, being Earth-elemental, she is perfectly suited for taking out the many powerful Ice heroes dominating the current PvP meta.

Can Soulburn an Extra Turn

Being able to Soulburn an extra turn off her S3 allows Yufine to kill reviving opponents like Arbiter Vildred where other DPS heroes may not be able to. Strike the reviving opponent at full force with Yufine's Soulburned S3, triggering their revival, then strike again with her extra turn and put them in the grave for good.

Spammable Defense Break

Yufine can cause Defense Break using her S1, meaning she can spam it throughout a battle for fairly consistent Defense Breaking.

Buff Dispelling

Not only is it not safe to be buffed around Yufine, it's not easy to stay buffed around her. Her S3 not only does more damage to buffed targets, but it also wipes all their buffs (assuming they survive the blow). Furthermore, Yufine's S2 dispels one buff from all enemies. Between these two abilities, Yufine makes staying buffed in a battle against her a difficult prospect.

Self-Buffs

Yufine may deny her enemy's buffs, but she has no problem with buffing herself. In addition to dispelling buffs (and Silencing), Yufine's S2 grants her an Attack and Speed buff when used. Nobody ever accused dragons of fighting fair, now did they?

Long Cooldowns

Most of Yufine's real damage potential comes from her S3, but her S3 also has a pretty lengthy 5-turn cooldown (4 turns after Skill Enhancement). The rest of Yufine's kit has a lot of utility to help her pull her weight while her S3 is off cooldown, but as a DPS hero, you're really waiting for her to get off that next huge nuke, and it can take longer than you might like.

Squishier Than She Seems

Yufine has pretty high base HP, but her base Defense is low, and while her kit is very powerful, it lacks sustain. On her own, Yufine has no ways to reduce damage, recover from damage, or otherwise protect herself from the enemy's assault. She needs defensive support from her allies in order to survive long enough to do her job in battle.

Requires Setup

The best way to use Yufine is to have her one-shot an enemy right on the first turn of battle. However, this isn't always as easy as it sounds. Yufine relies on her enemy being buffed to maximize her damage. If she outspeeds her enemies, they may not have buffed themselves yet and her damage may not be enough. However, if her enemies go first, they might hit Yufine harder than she can handle and one-shot her before she gets her S3 off.
