Editing Collect Arcane Catalyst (section)

====Hints====
: There are 6 Siege Engineers that spawn around each of the 3 catapults (the Seige Egineers tend to spawn in waves of 1 or 2 at a time. When the wave is killed, the next wave will appear until all 6 have been killed). When you kill all six of the Siege Engineers around a catapult, the red flag near the catapult will disappear and the catapult will be deactivated (i.e. it will stop shooting fireballs). When you deactivate all 3 catapults, a boss or bosses will appear (either a lich or 1 or more [[Obsidian Cabalists]]). You must kill the bosses in order to lift the seige, but you do not need to kill the bosses to complete the "Collect Arcane Catalyst" quest.
