Langrisser M - Ancient Beckoning Hugin & Munin (A 2,396,966 dmg, 35382 power)
An attempt with Narm (bow), Cherie (flier), Landius, Tiaris, Liana, and Varna (off-faction).
0:00 Initial preparation beefing Varna with more HP gears and 2nd bond. She is off-faction, so needs all the HP she can get to tank the AOE. Sadly, she survived only the 1st AOE with 17 HP, and died in the 2nd one. I will need to class master her, give her better HP equipment mastery stones, so I can push to S rank next month.
4:00 Overview of team composition
6:19 Phase 1 begins (9 clock of forgiveness chances left)
21:49 Phase 2 begins (7 clock chances left)
30:06 Phase 3 begins (6 clock chances left) - this is where Varna died and the fight got much more difficult to manage without Mass ATK.
49:05 Phase 4 begins (4 clock chances left)
53:52 Phase 5 begins (4 clock chances left) reached A rank
1:21:00 Fight ended and closing remarks.
Here is the overall strategy:
1) 5* Narm is the main DPS in this fight, dealing high bonus dmg to the Flier class boss unit. She brings Roundabout for repositioning and both attack skills.
2) 6* Cherie is more of a utility unit in this fight, using King's Crown to buff Narm up during the odd phases. She also helps take down the left spawn during the even phase (along with Landius).
3) 4* Landius is a great tank in this fight with the dmg reduction skills, such as Iron Helmet, which gives 25% chance to reduce ranged damage by 50%. Coupled with his Royal Calvary that reduces dmg by 45% when above 80% HP, he can tank the 1st single-target skill fairly well. His mobility and 2nd life are all good perks to have here.
4) 6* Tiaris brings amazing Healing Light to passively heal up Narm and Landius after battle. Her ATK blessing SKILL greatly amplify Narm's dmg especially when aligned with either of her attacking skill. I also bring Mass Heal to get rid of the MOV debuff after boss' AOE in later phases.
5) 5* Liana brings Act Again and Mass Protect. Act Again helps time Narm's attacking skills with ATK blessing on the same turn. Mass Protect is one of the key ability to mitigate the "disease" like stacking debuff after boss' AOE attack.
6) 4* Varna (off-faction) brings Mass ATK - this is her only JOB! Ideally, we should bring Chris (on-faction) if her right path is mastered. I mastered her center path and do not have 2 runes to spare just to get Mass ATK. The only problem is that my Varna's HP is too low to survive the boss AOE at the moment. This should hopefully be resolved next time Hugin & Munin comes around.
Food for thoughts: perhaps I should could abandon the Mass ATK/Resist strategy and not use Varna at all. Bringing Liana's Prayer instead of Mass Protect can also help top off the team after AOE. We could try DPS race + more careful tactical maneuver. In place of Varna, we could probably add (4*) Rachel, who is a good DPS, off-healer and debuff cleanser. We could perhaps also add (6*) Elwin. Will probably try again with a different strategy tomorrow!
Hope this is somewhat helpful for anyone else!
