# RoflLens

> RoflLens is a Python library and CLI for analysing League of Legends ROFL v2 replay containers and network transport. It exports blocks and payloads, and offers patch-specific decoders for events such as movement, spells and deaths when the client version, protocol digest and executable hash match.
