The notes also include a full rundown on the many, many skill changes for balance, including the overall philosophy behind trap changes and the many new gems added with the patch. Whether you’re in for the new League or just want to keep playing, there’s enough stuff here that you’ll want to survey all of it with a careful eye. So much to do and so much to enjoy when the patch goes live June 1st.
