None of the changes made to Steps of Faith has any bearing on the trial’s mechanics; however, Vishap and his attendant dragons all have less health, damage dealt by Underfoot and exploding cannon is reduced, and some enemies will deal less damage altogether. It won’t make the trial a simple matter to clear, but it will make clearing it far less demanding than before.
Final Fantasy XIV‘s main scenario quest? The last trial introduced, Steps of Faith, is a pretty decisive coordination check with very little margin for error. So a bit more margin is being introduced in the game’s most recent patch, which also adds new music for the various Primal ponies and increases the Echo strength in the Final Coil of Bahamut.
