The world ofWuthering Wavesis a chaotic one. After numerous disasters that continue even into the modern age, monsters called Tacet Discords run wild. Some of them are especially powerful and are classified as Overlords, and the Tempest Mephis is one such creature.

This Electro-wielding humanoid is capable of lightning fast attacks and combos, and wields its massive tail like a glaive as it fights. It may be terrifying, but you’ll need to fight it if you want to ascend your Electro Resonators and get your hands on them as an Echo to use against the many other foes you’ll fight.

How To Beat Tempest Mephis

Tempest Mephis is afast moving bossthatfrequently goes invisible, but during its invisibility, you’llstill be able to attackit. The best way toget its Vibration Strength downis byusing Counterattacks, and themajority of its moves can be counter-attackedand this will give you some time to get in some extra damage.

Effective Characters And How To Recognize Attacks

BothTaoqi and Baizhi are great for counter-attackingTempest Mephis, as Baizhi can hit them from a long range, and Taoqi’s slower attack speed gives you a better window to react and not end up being mid-combo.

The Tempest Mephis will mainlyuse a combination of quick slash attacks and tail swipes,as well as a two-partmove where it charges forward then disappears and does a ground slamwith a damaging wave. All of thesecan be counter-attackedwhen the Tempest Mephis’attack is surrounded by a gold ring, and it’llknock a big chunk of Vibration Strength offthem.

Stay Close And Beam Attack

Because of its speed and invisibility, you’ll want tostick close to the boss and keep attackingit as often as possible, as themore counter-attacks you do, the quicker it will be immobilized briefly.

While rarer than its other moves, the Tempest Mephis willoccasionally shoot a beam with a long attack rangein one direction. Make sure tododge to either side, then run up to it and get some hits while it’s standing in place.

Manage And ReduceElectro Flare Stacks

While fighting, you’ll also want tokeep an eye on the status effect it hits you withduring most of its moves: Electro Flare. If you haveunder four stacks of Electro Flare, you’ll have yourAttack reduced byfour percent.

If youget over five stacks, it’llreduce your attack by seven percent and inhibit your movement, and if it hits max, you’ll have a whoppingten percent attack reduction.

Yourlock-on effect works even while the boss is invisible, andit can help you know where it is constantly.

Electro Flarestacks will gradually wear offif youavoid being inflicted with moreof them, but most of Tempest Mephis' attacks can inflict it, somake sure you dodge as much as possible. If youget too many stacks, stick to theedge of the area to try and avoid the bossuntil they go down.

While the Tempest Mephis is fast, theamount of counter-attack opportunitiesyou getmake it easierthan someother Overlord class bosses like the Crownless, and even without knocking its Vibration Strength down, theboss takes plenty of regular damage.

Avoid bringing Electro userslike Yuanwu andCalcharoto this fight, as theboss has high Electro resistand won’t take much damage from them.

Taoqi can help you do good damage and canboth heal herself and reduce damage taken for any character, and entirely DPS characters likeLingyang, Spectro Rover, or Jiyanwork great atconstantly doing damageto the boss.

As for Echoes, since theTempest Mephis tends to keep nearyou, any close-range Echoes that do damage, like theChase Razor or Havoc Dreadmaneare great for extra damage. If you need more defensive options,Stonewall Bracer or Bell-bourne Geocheloneare great for theshields they provide, and theCruisewing can give you some extra healingif you need it.
