A1: Pretty easy before you reach the airship you must have 99 al bhed potions, and make sure auron can deal approximately 3000-4000 damage, so when you reach evrae start of with tidus rikku and auron, have tidus cast haste on everyone then use trigger comand pullout and switch from auron to wakka . wakka should be hasted , then as evrae uses photon spray(his attack while your far away from him) just use albhed potions. when evrae hp is weak (lets say 10000hp) hell use swooping sytche whice causes him to go closer and casts haste just simply use auron to knock him down

A2: Just simpley us two or three pheoix downs for instant kill trust me.

A3: Simply get all their overdrives and then train lulu till she has firaga watraga thundaga and blizaga then you simply get a crap load of softs and make all the armors impossible to be paralized
