Prayers on the ability bar makes prayer switching simple, and the latest graphical update made the animations pretty easy to track. In the old days you had to keep your head nice and clear so you could click to attack the healers, click to drink prayer pots, click to switch between prayers and inventory, and click to switch between protection prayers, all without misclicking. Now, everything can be done on the keyboard except attacking the healers, so you can keep your eyes on Jad the whole time and use hotkeys for the other stuff. Mage is better than range, but bring melee for the Xils; they're slow to kill with magic and you might as well save some time.
