Terra Gladiatoria is an island you visit when you want a tougher fight against groups of monsters. The battles on Terra Gladiatorla
are structured like the assaults on your bases in Story Mode. You can build up t~e island's central structure and add defensive
measures to help your battles. When you're ready to return to Terra Incognita, use a chimaera wing or the seal of Erdrick.
Battle tickets must be made at the forbidden altar. Note that you need a specific
tussle ticket to make trouble tickets, and a specific trouble ticket to make
trauma tickets.
