Thylessia Review

Thylessia is an Epic Attack Force champion from Knights Revenant faction in Raid Shadow Legends. Thylessia was introduced in Patch 4.60.2 as one of the four champions required to fuse Sigmund the Highshield Champion Fusion Event on October 2021! To obtain Thylessia, you will need to collect fragments of her through tournaments and events while Sigmund the Highshield Fusion is active!

Weft of Madness (A1 Skill) is Thylessia default attack that has a unique ability to spread debuff on hexed enemies. This synergizes well with single-target debuffer champions such as Drexthar Bloodtwin, which allows you to spread HP Burn debuff on all spiderlings in Spider’s Den to quickly dwindle down the Spider boss HP!

Melancholia (A3 Skill) enables Thylessia to inflict Decrease Defense debuff on all enemies to allow her allies to deal more damage on them! Shrieking Voices (A2 Skill) is another useful skill that increases debuff duration, so enemies will be under debuff for a longer period of time to reduce their battle effectiveness.

Last but not least, Thylessia has a passive skill Feast of Woe that allows her to place Hex debuff on enemies whenever she attacks an enemy under Decrease Defense debuff. However, the success rate is kinda low, which does not make her a reliable champion to spread debuff to all enemies in battle consistently by herself. Hence, it’s recommended to pair her with a champion who can 100% apply AoE Hex debuff such Ruel the Huntmaster.

    You got her speccd for a damage dealer when her real use is for the def down and increase debuff.

    Lots of speed and accuracy needed here. Theres better damage dealers out there

  2. BrainBird

    I’m not seeing the increase debuff work on provoke or stun. Is this accurate or am I missing something? It says “all debuffs”, but I use Visix and Big ‘Un a lot and was thinking that Thylessia might create some fun CC synergy. That was not exactly what I experienced. Any insights?

  3. Dinky Hocker

    @Fel – Yes.

  4. Fel

    Should I 60 her instead of Warmaiden as a drop def champion?

  5. Leo

    I’ve been using her for Dragon as well. Helped speed up my runs. Haven’t tried her much outside of that but will do so soon. I don’t regret lvling her (though I haven’t fully booked her).

  6. daniel

    She is 5 star for dragon
    if you run her with frozen banshee.she will increase the posions on the boss.insane A2

  7. Jerbearnicorn

    I’d give her 4* on Clan Boss. She does a great job of improving team poison damage with her extend debuffs and decrease defense helps everyone hit just a little harder, if you don’t already have it. I’m at the account level of doing about 27-29mil per key on UNM with budget unkillable. My Force team was lagging behind at around 23mil, just being below 3-key. She brought my Force damage up to even with my other affinities.

    @Mortar Mike: Stun set, you say? I hope you’re being serious here, because I just might try it. I’ve been looking for someone to speed up those KR crypt runs for a long time, and just 6-starred her yesterday without any playtesting (those champ training events/tournaments force my hand sometimes). Wasn’t sure quite what to do with her, but I wonder if she’ll make Thea viable. Would be nice to Auto KR 21 some day, during CvC, for the extra points.

  9. Mortar Mike

    Honestly, this is one of the best epics that they’ve added to the game in a while. The ability to crank out Hex debuffs rapidly, spread debuffs, increase debuff durations, AND AOE Def Down in one champ? Put her in a stun set and she can almost lock down waves herself, and paves the way for other Champs to do their jobs. Awesome champ.

  10. Fleafii

    Her a3 applies def down and the hex at the same time. (1 turn)
    Only 50% chance for the hex though

    @Jason: I have included Thylessia artifact and mastery recommendations to this page!

  12. sin

    her skills are a bit wonky. her passive should be 100%. cause you can get the hex out after two turn (if you don’t have anyone elso to put dec. def. before her), and it becomes useable at the 3rd turn. by that time most fights are over.
    I think putting her in stun gear would be best. relentless just doesn’t feel right.

  13. Jason

    Why dont you have any gear recommendations for Thylessia, or masteries? I assume HP% would be best for chestplate or ATK% better?

  14. Felix Javier

    If her health was 3K higher, she would be a beast.
