At first you need to have a jailbreaked device! If you haven't start a search in Youtube with "untethered Jailbraik and your iOS Version". If you have Cydia seek for "IApFree" and install it ( Note: It's directly against the law more info at cydias Description of the tweak). Open the App by clicking on its Icon and install the Core Plugin in the Plugin Download section. If you enable the App, now your In App-purchases should be free and you won't need to insert your password. So you are now able to get tear of venus and rag lotto for free. Buy some tear of venus and use them when you have been killed (that makes you theoretically not killable). Next you buy some rag lottos and use them. You can use the items yourself or you sell it and get much money to spend on whatever you want.
