Probably not new information for anyone having fought Adamantoise / Aspidochelone, but they heavily resist any magical damage other than Ice. In my mostly MP/MND Set (didn't have nuke set on me) as 78 RDM/WHM, Blizzard III did a solid 531 dmg each time.
They resist Gravity also, but it can land. Bind, Paralyze, Blind will land easily but I didn't managed to get Slow II to land with around 330 uncapped skill, HQ staff etc. Neither could I get Sleep to land. -- Orubicon 23:12, June 29, 2010 (UTC)
