The Caste doesn't have a special effect like Tamers. Each Gladiator has a different effect if they already faced the opposing character during the game or similar.

Valerius a écrit :
If Valerius has already faced the opposing character during the game, at the start of the fight, the opposing character has Attack -1 and Defense -2.
If one of those doesn't work, it's a bug... They worked correctly during the tests. Are you use Soul characters?
