Andreas and I have completed the missing content from above. However there are a few issues we need to resolve.
Players are not able to select multiple prayers on the same game tick. The issue likely stems from the task priority level overriding the previous prayer activation, so only the last prayer you clicked during a game tick will be activated.
Allow summoning protect prayer to be combined with protect melee, missiles, and magic.
Finish implementation of quick prayers.
We will need to add curses once we add the quest Temple of Sillestene.
