Welcome to the Communication Overflow Summoner Build Guide! This build bases most of its damage on her "Pets" (Summons), her little AI-Controlled companions, which she can micro-manage to attack the desired target or move around with her by pressing the Left-Shift key.

Communication Overflow summons powerful minions to aid her in combat, while using Ancient Energy to call forth powerful Ancient Elementals. It's a very active play-style with high amount of casts.

Due to the variety of creatures, Summoner brings a lot of Destruction and Stagger to a raid. It also provides Defense Reduction Synergy.

  • Ranged
  • Non-positional gameplay
  • Squishy
  • Companion AI
  • High APM

Want a slower but bursty playstyle based on her Identity? Check out our Master Summoner guide.

  • Water Elemental is your Counter skill. It's a Normal skill, not a Summon skill, which means it doesn't benefit from your class engraving.
  • Elcid is your Synergy skill. It reapplies it every time it attacks.
  • Ancient Spear is your most damaging skill. It also generates a good amount of Ancient Energy.
  • Earth Collapse is your second strongest Normal skill, also generating a decent amount of Ancient Energy and dealing Destruction.
  • Shurdi is your Crit Rate self-buff. It also increases party MP regeneration thanks to its MP Recovery tripod.
  • Maririn and Pauru are your strongest Summons.
  • Steed Charge is a high-stagger skill with high damage and Ancient Energy generation.
  • Kelsion is also a Summon buffed by class engraving.

Alternative Skill, Tripod, and Rune Options


  • Precision Fire
    • This reduces your potential damage (due to Quick Recharge procs) but also simplifies the usage. If you pick this tripod, swap the rune to Wealth.

Check the Rune Guide for more details on Runes and how to obtain them.

This build is optimized and meant to be used only in Chaos Dungeons. For Ebony Cube please use a Raid build.

  • Most of your skills have good AoE.
  • Maririn is used to draw attention of enemies
  • Steed Charge generates a lot of Ancient Energy, allowing you to spam Phoenix for AoE damage.

Acquiring additional engravings leads to a faster clear potential, but the build can perform quite well with the bare minimum.

Minimum requirements

  • Preemptive Strike causes your attacks to deal immense amounts of damage to monsters that you haven't attacked yet, making it ideal for Chaos Dungeons.

Additional engravings

  • Contender is a stacking Attack Power effect that increases in strength once you kill a monster, making it ideal for Chaos Dungeons.
  • Raid Captain provides damage based on your Bonus Movement Speed, synergizing well with the Buff Nodes scattered throughout Chaos Dungeons.
  • Hit Master provides an unconditional damage boost to your skills, as none of the important ones have a positional affix.

Gameplay & Skill Rotation

Communication Overflow provides Damage, Atk. and Move Speed, reduced cooldown as well as extra duration to your Summons ("Pets").

Her identity consists of 7 "Ancient Orbs", also called Ancient Energy, and 5 different Ancient Spirits.

  • Osh: Costs 3 Orbs. Deals Destruction and low damage.
  • Alimaji: Costs 4 Orbs. Deals Destruction, Stagger and decent damage.
  • Phoenix Costs 5 Orbs. Deals Destruction and decent AoE damage.
  • Jahia & Ligheas: Costs 6 Orbs. Deals max Stagger and creates a Shield on you.
  • Akir: Costs 7 Orbs. Does decent Stagger and very high damage.

Summoner Identity

Ancient Spirits, Ancient Energy

This build focuses on consistent damage through your Summons, and good utility through your Identity. Summons don't necessarily require management but knowing you can force them to attack a specific target (by pressing Shift while hovering said target) can help you focus their damage.

With her preferred stat being Swiftness, her cooldowns are low which means your pets are active all the time. Some of your Summons also have "active" skills while they're summoned, allowing you to force them to do special attacks (which they don't perform on their own).

Basic Rotations


  • You always want to have these pets summoned.
  • Elcid's Deadly Poison Seed can be stacked during damage reduction mechanics or patterns. Pre-summoning it will lead to better damage as long as it can hit the boss.
  • Shurdi provides you with a Crit Rate self-buff from Shining Growth, and you and your party with increased MP regen through MP Recovery.

General Rotation

  • Maririn - Charge and Pauru - Flame Breath are their active skills. You should use them whenever they're up.
  • Akir should be used if you have enough Ancient Energy as a damage filler. Ideally used to cancel Ancient Spears animation.

Stagger Check Rotation


  • Remember you can also use a Whirlwind Grenade if you have one equipped!

Tripods and Gems

Tripod Levelling

Increasing the level of Tripods greatly enhances their effectiveness. You may only increase the level of 18 tripods at a time. Some of them cannot be leveled at all, or are left at level 1 - these tripods are omitted from the table, even if they are used. Here are the main tripods you should look out for in order to maximize this build's potential.

Gems are another significant aspect of your build, as they directly impact the damage and cooldowns of your skills. You can equip up to 11 gems at a time. Here are the ones you should focus on in order to maximize this build's potential, listed according to their priority.

Engraving Explanations

Core Engravings

  • Communication Overflow core of the build, as it boosts all your summons.
  • Adrenaline provides an additional source of Crit Rate and Attack Power. It is fairly easy to upkeep.
  • Grudge increases damage done while also increasing damage received. The engraving is a highly effective damage increase without needing specific positioning, making it worthwhile even with the penalty.
  • Keen Blunt Weapon is a great choice when paired with all the Crit Rate you seek to have.

Add-on Engravings (Pick 1)

  • Raid Captain provides damage based on your bonus move speed, which is inherently high due to your Swiftness stat.
  • Cursed Doll is a significant Attack Power increase at the cost of 25% healing. The healing penalty can be punishing for inexperienced players who are not familiar with boss mechanics, but it becomes easy to overcome with time.
  • Hit Master provides multiplicative damage but it doesn't affect your Awakening nor Bleed Rune damage.

Level 1 and 2 Engravings

  • Adrenaline is your ideal +2 engraving.
  • Master Summoner (Level 1) is your best +1 engraving, improving your identity utility as well as reducing the Ancient Energy cost.

Check out the Engraving Guide for more details.


Bracelets provide beneficial effects to yourself or to your party members depending on the rolls they have.

The primary goal is to get the main stats used by this build Swiftness and Crit. After that you should be aiming for Special Rolls to get more damage. Please note that this system is heavily reliant on RNG, and you should not expect to get much more beyond your main stats early on.

Optimal Bonus Rolls

Hammer + Wedge

Alternative Bonus Rolls

Wedge (without hammer)
Weapon Power

Check out the Bracelet Guide for more details.


The recommended Elixir Set for this build is Critical.
Master is a viable option too.

Check out the Elixir Guide for more details and general stat recommendations.

Card Sets

Cards are an endgame system that helps maximize your character's damage. Here are the recommended card sets for this build.

  • Deep Dive is used early on as it is fairly easy to obtain.
  • Light of Salvation is the standard endgame option, but it can take a long time to acquire 30-piece Awakening.
  • Kazeros's Legion Commanders is used as an alternative to Light of Salvation, in content where enemies have a weakness to Dark Damage.

Check out the Card Guide for more details on how to obtain cards and interact with them.
