1- Be a Guild master (not sure if works with all the guild permissions too)
2- Have enough GP's for spend in your guild (not too much)
1st: Go to the Hotan Guild Manager Musai and purcharse at least 10 of each element on the Guild store (I just tested the purcharse of them as a Guild Master)
2nd: Go to Jangan/Hotan Fortress Administrator and purcharse the 2 lasts scrolls (Ram Summon Scroll Recipe and Catapult Summon Scroll Recipe). Then use them with a right click on your inventory.

4th: Press craft. You can make up to 1 scroll of each COS every 3 hours. Catapults and Rams can only be summoned during Fortress War, inside the Fortress War. That's all ^^
