Places up to 4 totems set on the Totem Bar | Level 20 |
| 30 | Call of the Ancestors |

The tooltips back up the levels. Call of the Spirits names both of the other sets, so it’s the last one you get.
All three take 3 sec to cast and put down one totem of each element. The post says each one costs the four totems’ mana added together. None of them has a mana cost in the client, which fits a cost the server works out when you cast. Game files · build 70291
The totem bar from 20 to 40
- Level 20: Call of the Elements opens the Totem Bar.
Totemic Recall comes at the same level and destroys your totems for 25% of their mana back. - Level 22:
Totemic Projection moves your active totems to a spot within 30 yards, on a 1 min cooldown, for 25% of base mana. - Level 30: Call of the Ancestors, the second set.
- Level 40: Call of the Spirits, the third.
Totems trigger a 1 sec global cooldown in Forever, down from 1.5 sec. Buff totems such as Strength of Earth and Windfury last 5 min instead of 2, and Healing Stream and Mana Spring went from 1 min to 5. Game files · build 70291
