Magic Team Party Supporter and Attacker
He possesses multiple support effects for Magic-type Heroes, making him a recommended supporter and attacker for Magic team parties. His unique feature is "Guardian Spirit," which grants Damage Immunity and Crowd Control Immunity after 2 turns, making him especially effective as a counter to Buff Duration Reduction Heroes.
High Priority for Skill Enhancement and Transcendence
| Enhancement | Additional Effect |
|---|---|
| Skill Enhancement | - Magic Damage Dealt Boost for 2 allies (Basic Attack) - Debuff Removal (Skill 1) |
| 2 Transcendence | - Guts + Barrier generation upon Guts activation |
| 6 Transcendence | - Ignore Defense (Skill 2) |
With many additional effects from Skill Enhancement and Transcendence, he is a Hero for whom both are high priority. You should aim for at least 2 Transcendence, and reaching 6 Transcendence is recommended if you plan to use him in PvP.

O'Mok Strength and Features
Guardian Spirit Countering Buff Duration Reduction is Strong
Applying "Guardian Spirit" to Magic-type Heroes grants them Damage Immunity and Crowd Control Immunity after 2 turns, making it an effective counter to effects like the Buff Duration Reduction + Fear combo from Mist.
However, note that the effect will not trigger if it is removed by Buff Removal.
Excellent Offensive Buffer
She is also an excellent offensive buffer, providing a Magic Attack Boost via her passive, a Magic Damage Boost for 2 allies on normal attacks, and Defense Reduction when she is incapacitated. While she is primarily suited for PvP, she can also be used in PvE content like Advent Expedition in some cases.
Capable of Acting as a DPS
She can also function as a DPS, capable of HP Alteration against the enemy with the highest Defense and AoE Ignore Defense attacks. With Camouflage making her difficult to defeat early in the battle, along with Authority, she excels in all areas—attack, defense, and support.
Guardian Spirit is Difficult to Utilize in the Real Time Arena
While Guardian Spirit is an excellent counter to Buff Duration Reduction, its inability to be activated at a chosen timing and the risk of it triggering too late are drawbacks. Additionally, because it is neutralized by Buff Removal, she can be somewhat difficult to use, especially in the Real Time Arena.
New Ruby Farming Meta
O’Mok stands out as a top-tier contender for Ruby farming, specifically optimized for clearing Nightmare Mode Stage 26 at lightning speed. By leveraging a Bounty Tracker build, she transforms into a high-yield resource farmer without sacrificing clearing power.

Recommended Equipment Sets
| Set | Recommended Reason |
|---|---|
Bounty Tracker | - Balancing Weakness Hit and Crit is important for PvP attackers. - Bounty Tracker is recommended when used with Rin. |
Assassin | - Balancing Weakness Hit and Crit is important for PvP attackers. - Choose this if you prioritize Crit. |
O'Mok is a Hero capable of dealing high damage, so it is recommended to balance Crit Rate and Weakness Hit Chance with Bounty Tracker or Assassin equipment. Bounty Tracker is particularly effective when used together with Rin, who has a Weakness Hit Damage Boost.
Bounty Tracker Set (Weakness Hit Type)
| Set | Main Stat Candidates | Substat Candidates |
|---|---|---|
Bounty Tracker | 【Weapon】 - Crit Rate - Weakness Hit Chance 【Armor】 - All Attack (%) | - Speed - Weakness Hit Chance - Crit Rate - All Attack (%) - Crit Damage - Effect Resistance |
When using Bounty Tracker, focus on increasing Weakness Hit Chance and Crit Rate with your options. Increasing Attack also allows you to raise the HP-based damage limit and increase the durability of the Barrier generated when Guts activates.

| Set | Main Stat Candidates | Substat Candidates |
|---|---|---|
Assassin | 【Weapon】 - Crit Rate - Weakness Hit Chance 【Armor】 - All Attack (%) | - Speed - Weakness Hit Chance - Crit Rate - All Attack (%) - Crit Damage - Effect Resistance |
The recommended options for Assassin equipment are the same as for Bounty Tracker. Aim to get both Crit Rate and Weakness Hit Chance as close to 100% as possible.

Since O'Mok's durability after Camouflage or Shield expires is not very high, the Ring of Immortality is recommended. If using her as a support by increasing durability, the Ring of Resurrection is also an option, but since she possesses Guts at 2★ Limit Break, the Ring of Authority is not recommended.
