The "Into the Depths" 3-day event takes place approximately every 15 days. Contrast that with the 3 events listed below, which also offer titan potions as a reward, but occur every 4-5 weeks in this order.
Players should also take note of an event for titan artifacts. [Please combine this list item with the previous list, if this event also offers titan potions.]
There is also a 1 time event for titans, which starts for players reaching team level 60. Because levelling up various features for specific heroes [e.g.: a tank hero's gifts of the elements, warrior's skills, warrior's skin, etc.] must be done during the event, players at team level 57 are advised to see what needs to be levelled up during the event, and then not level those things until the event quests require it.
