Hi guys, not sure if this is a widely used combo but having Blood Sword on a dual wield character with auto-refresh (so Lightning, Luneth or DW on DKC, Delita, Ramza) basically creates an exploration machine that can't be killed by anything outside of Elite vortex events.

On a 400 atk unit Drainer will hit twice for pretty decent damage, heal hp to full and cost a negligible amount given auto-refresh. This is great on a friend unit when you're trying to single unit party full clear xp farm Aquatic Cove or Mystic Woods to level up that new CoD/Refia/Luneth/etc.

Just thought I'd throw it out there as I haven't seen anyone mention it anywhere and it seems really effective. I know most people will still lean towards maxing attack instead but if you're not rocking TM weapons it's worth checking out (or maybe even if you are). Also means you no longer need to bring a healer just in case who will suck up half of that sweet sweet XP.

ps: Drain Blade is a reasonable alternative too if you'd rather stick to high damage weapons have you have an ability slot free

edit: fun extra tip: if you're leveling CoD in Cove give her Siren and Drain Blade, she'll have 100% water res which will make it all extremely easy (also Spirit Slayer helps).
