Vidala in Escha - Zi'Tah will cast Break on you as its first action before you can engage in melee. If you can buy Mirror Tonics, use those, but I couldn't find any info on how to unlock them. I made a rundown of Jobs that, from my observations, *might* be able to survive the first minute solo with Trusts against this jerkbag tiger, but had to cut it short to fit.
The short version is: BLM Stun and NIN Utsusemi, or any Job as /BLM or /NIN, are probably the safest options. Others include PLD: Fealty; RUN: Barstone+Barpetrify+Flabra x3+Pflug; BRD: Nightingale+Troubadour+Foe Lullaby II; RDM: Spontaneity+Sleep II. A couple of iffy ones are PUP: Provoke (pet) and DRG: Super Jump, because you still get petrified while your automaton tanks for a minute and the timing is too luck-based for Super Jump.
