Gladiolus (boss)

The player can train with Gladiolus on campsites. New training levels are unlocked as the player levels up, and the Final Trial is open in Chapter 15. Completing a training session earns 5 AP. Gladiolus does not appear in the bestiary.

The player can use the Ring of the Lucii against the bros in Chapter 15. The player can use Armiger, but there are no point-warp spots and summons never trigger. The player can train in any time of day and in any weather. The training partners' stats and gear are not the same as when they are party members, and their food buffs don't carry over to their training partner forms either. The player can use Elemancy, but the training partners never do.

Battle
Training is available on havens on the continent of Lucis when the required party members are present. When Gladiolus is away in chapter 7, the player can only train with Aranea while she is a guest.

The training ends when Noctis is knocked to Danger state and Gladiolus comes with the rescue animation. The player needs to quickly heal if they don't want to end yet.

Gladiolus uses same battle maneuvers as when he is AI-controlled as a member of the player's party. He doesn't use maneuvers from his player-controlled state, as that was added to the game later.

Gladiolus can block with his shield and counter.

Final Trial
The player should defeat Ignis first as he heals the others. The player can then defeat either Prompto or Gladiolus. Warp-striking with their weapon weakness (especially point blank crital) defeats Ignis and Prompto quickly. Counterattacking Gladiolus after blink-dodging works well. Blink-dodge helps since the player can directly counter or warp-strike after for good damage.
