Play through the game, and get past the Cyclops and into the Trophy Room where you can find the hidden door to meet Oliphant. Talk with him until he tells you that you have not found the "Book Of Right". Select "We Begin Again", and you will get a lot of experience. Leave his room to go back to the Trophy Room, and either die or reload your saved game. Talk to him again to get more experience. Repeat this as many times as desired. Even at high levels (like 98), you can level up by talking to him just three times.Opening chests without picking the lock
Face a locked treasure chest so the hand appears on the touchscreen. Go to the character screen by selecting the stick figure at the bottom right. Tap on your bag, and you will see the items that are in the chest appear on the left side. You can take them without picking the lock.
