Gear for Multi Pitch Rope Solo Climbing

What gear do I bring for one day of rope solo climbing? In this case multi pitch in Donautal, Germany.
For belaying myself when leading I am using the Petzl Grigri. For top rope soloing I am using a Climbing Technology RollNLock and a modified Petzl Ascender. Rope is a single rope by Maxim Ropes.
I shown the method on how to climb alone in another video. With this method you can climb without a partner whenever you want. But sure, you have to master belaying and know what carabiner to open and what to do. Don't be silly, don't climb alone ;-)
