I tried straight tanking this with a BRD friend today, it went better than expected but we still wiped. It was my first time ever trying this setup, here was my gear, any input would be appreciated:
Tutlary
Genbu's Shield
Bibiki Seashell
Warlock Chapeu+1
Beak Necklace+1
Loquacious Earring
Ethereal Earring
Darksteel Harness
Protecting Bangles
Jelly Ring
BQR
Cheviot Cape
Swift Belt
Goliard Trews
Goliard Clogs
Over all I had 26% -Phys taken, 36% at night, +10 VIT from gear/spells and roughly 700 defense with Prot4 and cocoon. Charybdis was hitting me mostly for 0-40 with all my buffs. With Slow2 and elegy it was possible to cast stoneskin without him attacking since SS was a 20s recast and he attacked roughly every 11 seconds or so. We lasted for about 30min with most of the dmg coming from bio2/poison and a little melee but eventually lost at like 70%. People who've soloed him using the kite method on /BLU say he was so easy its possible to straight tank him, which I tried tonight to no avail. Would it be more efficient to just try again but this time simply bind/nuke? The brd didnt wanna sleep the devil manta for an hour so is it possible to kite charybdis up and down that little piece of land between the pond he spawns in and the secret door?
