This means Riot can remove, change, or eliminate your virtual items and currency without compensation, even if you paid real money for them.
Riot Games' Terms of Service significantly limit consumer rights by requiring mandatory individual arbitration and waiving the right to participate in class action lawsuits. Players have no ownership rights over virtual items or currency purchased, and Riot can terminate accounts or discontinue services at any time without refunds. You can opt out of the arbitration clause by sending written notice to Riot Games within 30 days of first accepting the Terms of Service.
