Well... I know I'm a little early, but Dullahan is coming to a soon end later today! We'll have a little break, then advent!
I hope everyone is prepared for Vritra!
What are your formations and weapons looking like?
NLB - Water Attribute up 20% / burst streak up 20%
MLB - Water Attribute up 30% / burst streak up 30%
(like medusa, typhon..) not likely to replace Jorm... summon ability applies drowned debuff.
Normal ATK - around 2K to 1 ally
Normal Overdrive - 3-4K to all allies
Raging ATK - again, around 2K to 1 ally
Raging Overdrive - 4-5K to 3 random allies
(just from what I've seen from videos, though i'm not 100% sure.. correct me if I'm wrong. and that's without ATK debuff, so it can be lowered... a lot, also luckily she has no debuff to allies or buff to herself. just hit hard, can be tricky without healer.. also maybe also good idea to use Mordred for max overdrive so not as many strong attacks..?)
Spoiler Video (Vritra Ragnarok battle)
I'm not too sure about advice, but I recommend of course to use Ixion as sub eido, as she gives more thunder attribute from her summon ability. can be nice before burst... if you're uncertain then probably best to use a healer as soul, as no thunder healers.. as for me, I'll probably just try with Arthur w/ Sniper Shot as EX ability.. Tyr with her debuff too can be nice.. Perun is a nice help too, though being a R partner, she has the same ability as Arc/Gaia. (maybe not the best idea, probably better for me to use another soul but.. just want to experiment. maybe i'll use a different soul for Ragnarok battle.)
Ultimate mode should be easy at least, though attempting Ragnarok won't hurt. I think I will... After Dullahan we have nice amount of gems so... hopefully we can focus just a little on leveling and upping skills of thunder assault weapons.
good luck everyone
if anyone has any advice, information or w/e feel free to help
sub team are Baal and Verethragna ... weapons are OK level, assault ones being 9 or above, defender ones 8-14 skill level.
