Classic pets and mounts
| Icon | Name | What it does |
|---|---|---|
![]() | Unicorn | Mount that raises movement speed |
![]() | Dinorant | Flying mount, faster movement and entry to Icarus; the community wiki adds damage +15% and 10% absorb |
![]() | Imp | Damage +30% |
![]() | Guardian Angel | Absorbs 20% of damage taken |
![]() | Dark Horse | Dark Lord only mount with the Earthquake stomp |
![]() | Dark Raven | Dark Lord only pet that attacks with you, alone or at random targets |
The community wiki also lists later pets: the Demon (damage +40%), Spirit of Guardian (absorbs 30% of monster damage, max life +50), and the Panda, Skeleton, Unicorn pet and Rudolf, which pick up Zen automatically. The Panda adds 50% EXP and the Skeleton 30% EXP and 20% attack.
Dark Horse and Dark Raven
Both Dark Lord pets have their own level. Season 9 raised the maximum level of the Dark Horse and of the Dark Spirit (the raven) from 50 to 70 and made the raven lose life more slowly. The raven now needs 185 + (its level × 10) Command, and its chances for Excellent damage, double damage and ignoring defense grow with Command and its level.
When either pet dies it leaves a spirit. The Trainer in Lorencia (123, 110) can bring it back with Resurrect Spirit, according to the community wiki:
| Pet | Materials | Zen | Rate |
|---|---|---|---|
| Dark Horse | Spirit of Dark Horse, 5 Jewel of Bless, 5 Jewel of Soul, 1 Jewel of Creation, 1 Jewel of Chaos | 5,000,000 | 60% |
| Dark Raven | Spirit of Dark Raven, 2 Jewel of Bless, 2 Jewel of Soul, 1 Jewel of Creation, 1 Jewel of Chaos | 1,000,000 | 60% |
Fenrir
The Fenrir is a giant wolf mount for every class that raises movement speed and attacks with its own skill, Plasma Storm (50 mana). In the 2013 official guide a character needed level 300 or higher to use it. It has 255 HP, can be hurt, and is healed with a Jewel of Bless. Its parts drop in Crywolf Defense.

| Stage | Materials | Result | Rate |
|---|---|---|---|
| 1 | 20 Splinter of Armor, 20 Bless of Guardian, 1 Jewel of Chaos | Piece of Horn | 70% |
| 2 | 5 Piece of Horn, 10 Claw of Beast, 1 Jewel of Chaos | Broken Horn | 50% |
| 3 | 1 Broken Horn, 3 Jewel of Life, 1 Jewel of Chaos, 10,000,000 Zen | Horn of Fenrir | 30% |
A Horn of Fenrir can then be upgraded in the Chaos Machine with 5 Jewels of Life and 1 Jewel of Chaos. Adding a weapon gives Horn of Fenrir +Destruction (final damage +10%); adding armor gives +Protection (absorbs 10% of final damage). The old guide used a +4 item with option +4 or higher and warned that the Fenrir can be lost; the Season 13 page lists a 79% maximum rate, any item level and Magic Stones instead.
Riding rules
- Since Season 9, the Horns of Unicorn, Dinorant, Fenrir and Dark Horse count as mounts. They are equipped from the inventory, and only one can be used at a time.
- In Icarus the Dinorant, Fenrir and Dark Horse work but not the Unicorn. In Atlans only the Fenrir and Dark Horse work. No mount can be used in Chaos Castle.
- Season 16 Part 2 allowed riding in towns and safe zones. Attacking makes you dismount automatically, and you mount again 3 seconds after you stop dealing damage. Ctrl+Z keeps the mount's speed after dismounting.
- The same update turned mount skills into character skills while the mount is equipped: Earthquake (Dark Horse), Plasma Storm (Fenrir) and Raid Shoot (Dinorant). Spear Stab was removed.
Newer seasons added mount-type Guardians and mount-type Muun.
