Shaking Hall - 1 is the first level of Shaking Hall - the first cave in the Chronicle Cave.
"Cave 1: Shaking Hall" unlocked. At the end of the cave, Dark Shaman appears and locks the door to the next cave and he also got the legendary Red Pig Key that can open all Red Pig Gates. Defeat him and grab the key.
Warning: In every waves, when the Rage Chili is full, use it on Red if you want to smash a high health enemy, on Matilda if your birds' health is too low (necessary when a Brute Pig or a Witch Doctor hits you too much damage) and on Adventurer Pig/Prince Porky when you want to damage all enemies at the same time.
Choose Red in Samurai, Matilda in Druid and Pigiana Jones' Adventurer Pig. In every waves, attack every turn with Red and Adventurer Pig. Then, heal with Matilda if the birds' healths are not full, otherwise, attack with her. When, the Rage Chili is full, do as what we said at the "Warning". At the end of each wave, it'll be nice if you activate Adventurer Pig's Counter on Red when the last pig in the wave is about to die with one more hit. Repeat this over until you win the entire battle or lose the entire battle.
