@Plutonium You could try Doomknight V2 and invite Sir Leon and Artix. Train 200 mischief, fighting and assistance on your dragon in that order. Equip a light weapon and use Corruption, Warcry with Sir Leon and DPS with the rest. Then, Drain Will for the -100 immobility resist and Dragon''s fume, reducing her immobility resist to 0. Stun with Sir Leon. Activate Dark Ritual for the burst. Activate Dark Favor if you can kill her fast enough. Otherwise, just use your best damage ability.
Edit: I believe Wrath heals 100% of the damage from critical hits. So if possible, try to use equipments with minimal crit and don't use Sir Leon final attack. A good helmet to use is the Magi helmet you can get from one of those Inn Challenges. It lowers your bonus as well but your pet can boost it up so you have nothing to worry about. Get STR stat instead of INT.
Her attack pattern : Buffs either 200 bonus, 100 boost, 200 crit or 200 BPD for 1 turn > attacks for 2 hits > Buff (look at first attack pattern for what buff) > attacks for 4 hits > Buffs > attacks for 6 hits > Buffs > Nuke (not sure how many hits) > Repeat
If possible keep your blind and boost down for the nuke. If she buffs her bonus, Boost down with your doom knight, Dragon and Sir Leon. If she buffs her boost, blind her with doom knight and Dragon(you should still boost down with Sir Leon anyway since it's a short CD). If she buffs her crit, choose either blind or boost down stacking. If she buffs her defense, use your defensive ability on doom knight, tickles on dragon, defend on Sir Leon.
Note: I do not have have Doomknight yet (1 year and 10 months more), so I'm not sure of its burst. If you do not have enough damage, you might want to avoid using Dark Favor too early.
I hope it helps you, sir.
