i am having so much trouble defeating myridia!! i have no clue what else to try!

wow that's the first time I have seen someone makng a post about this boss, I had to actually go look up which boss it was
Myrida, right

First question, is your party:
Kenja, Fenimore, Masuku (in that order, slot1-3 on the party page? If not, who is in what slot?)

Assuming that is your team and the order, I'd say first order of buisiness is to get them equipped with lv50 legendary gear (common reward from lv50 mission satchels, pretty easy to get off of the Trade Broker usually)- Illusionist for Kenia, Evoker for Fenimore, Myrmidon for Masuku

(To illustrate the difference, Kenja's got a lv55 rare relic, which gives her +170 to her damage stat, and hers is the best relic between the three of them. A lv50 legendary relic gives +260, which is nearly 100 points more than what she's currently got (and is more than double what the other two have))

So, step 1, Equipment upgrade!

step 2, I'd say swap Fenimore and Masuku to either 2attack or 1attack/1dex; more attack on Fenimore means higher heal return for the party, on Masuku higher dex means greater chance to inflict damaging debuffs on opponents


step 3, in the fight, block when she's at full mana to protect your pets from her big attack+Haunted debuff

thank you for your help! my biggest issue with gear atm is i cant seem to save up enough gold. i have only gotten up to like 30k before spending it on gear just to be told that i need better to advance. i currently have 445 gold lol :P with so much going on in life rn i don't have the time to sit and grind for hours to make gold, so i guess ill just have to be stuck for a bit ^<^ thanks for the advice though!!

well, that's what Missions are for, really- you send your mission pets on missions, get the gold reward, get the mission satchel reward, open the mission satchel(s), then either keep or sell what you get from those

I really do absolutely endorse doing missions- you only need to send the right pet on them and that's it, no more work on your part, and you can get equipment, gold, healing items, and very rarely pet essences from the reward satchels
(see: guide to missions and mission pets)

(they also raise your reputation with their respective town)
(and it gets better the longer you do them- you can buy more mission slots so you can have more going at once for a total of six. Six lv25 very hard missions is baseline 18k)
