Gwynneth joins the Dark Elves as part of the second set of fragment champions earned from the Doom Tower Secret Rooms. Doom Tower Fragment champions cannot be summoned.
Her brings unique mechanics and in some scenarios makes her an MVP. With her A2, if you can keep her relatively full HP, she can produce some record breaking numbers for AoE Healing as the excess heal (the amount she doesnt need to fill her HP bar) is healed to all allies. In addition, she will also place Weaken before attacking meaning she becomes an Affinity friendly debuffer. Her A3 will transfer any debuffs to the target enemy and then 10% of the target’s defence for every debuff active. This becomes an incredibly hard hitting ability in places like Clan Boss. She also has an AoE A1 which makes her viable for a Stun Set and this also will not trigger Counter-Attacks, something which is always an issue with champions that are AoE (such as Psylar).
She is an absolute MVP for Agreth, the Nether Spider in Doom Tower. Her A3 will transfer poisons back to the spider whilst her A2 will heal up your team. The A1 then won’t trigger the spiderlings counter-attacks which would normally heal the Queen (which makes most AoE a1 champions unviable). She can also pump some incredible numbers in Clan Boss and has a speed aura for doom tower making her a great support for the waves. Keep in mind: She needs Accuracy and damage to be able to utilise her A2 and A3 so the build will need to be strong.
