Overview
The durable spell scroll is a specialized creation of the Societas Magica Historica - Mage Scholars. Specifically those members in Zweiflus where the art was discovered. Functionally a durable spell scroll works the same as a regular spell scroll, but it has a chance of surviving with a successful arcana check of dc 10+2x the spell level. So a 2nd level spell would require an arcana check of 14. On a success the spell scroll survives but can’t be used again until you take a long rest. On a failure the scroll burns up like normal.
