Warlord Skills

Click the 『Camp』 in the bottom left of the battle screen. 🔸Deck (Left) → You can see the summon rates. 🔸Illustration (Right) → You can see the Warlords & Skills you've unlocked. I've seen the 『Camp』 enter an explosive state before. The next summon is guaranteed to have a Warlord's name. But I don't know how that state is triggered.
