Bahamut illusion at world end, extra mode Seer/Thief Used the heck out of reincarnation and teleport see equipment end video.
Skip first 30 secs , can also skip to around 8 minutes after died 3 times in row. With 400% white mage get auto revive once, I believe when use reincarnation from seer it resets auto revive like save cube. Multiple times during long battle Ive died twice in row before getting reincarnation back up so that has to confirm reincarnation resets auto revive.
With extra mode no filters permanent chaos mode so no worries about mp. Ive tried multiple combinations of other characters with extra mode but never able to time dodges. Even after remembering teleport I'd still miss one dodge and die 2nd time after auto revive because couldn't get away fast enough. But, with seer/thief combination and teleport able to keep up teleport dodges as long as kept up wit all refreshes.
I want to try other combinations with teleport once setup nice combination for increased mp regen so can do these bosses without extra mode. My reflexes aren't as quick as used to be 40 years ago. ^-^
