Water build for Conquest Season (v2.8.3)
Infinity Kingdom Water Build Guide: Conquest Season Edition
As players progress into the Conquest season in Infinity Kingdom, the Water element composition gains access to its most refined and powerful form. With top-tier Tower of Knowledge (ToK) skills now unlocked and dragon talent trees fully available, this is the season where your Water march can truly dominate. This guide builds on our earlier articles on Season 1 and Season 2 water setups and takes you into the final optimized version for competitive PvP in Conquest.

Core Immortal Lineup for Conquest Water
The Conquest Water march builds on the core composition from Season 2: Artemisia (or Dido), Merlin, Ragnar, and Bjorn (or substitutes like Attila or Hippo if needed). This lineup provides an excellent balance of burst magic damage, crowd control, support sustainability, and debuff synergy.
Immortal Skill Setup
Artemisia (or Dido if Artemisia is unavailable):
- Assist
- Heart of Arcana
- Weakness

Artemisia provides the early energy and chill support required to set up Merlin. Assist ensures Merlin is protected and has the highest troop count, ensuring he receives fewer debuffs. Heart of Arcana gives a massive +35% magic damage boost and is essential to scale your burst output. Weakness increases your critical hit chance, making Merlin’s high damage spells even more lethal.
Merlin:
- Corrosive Power
- Psionic Tide
- Fighting Master


Merlin is your nuclear warhead. Corrosive Power triggers a cycle of +60% boosted ultimate casts every 3 activations, and Psionic Tide gives him a rapid +200 energy injection after each ultimate. Fighting Master protects Merlin from critical crowd control effects, particularly from Shadow teams that rely heavily on silence and freezes.
Ragnar:
- Weakening Curse
- No Escape
- Malice


Ragnar is the glue that holds this setup together. With his innate support from his talent tree and his frontline tank synergy, he becomes a powerful utility tool. Weakening Curse lowers enemy resistance, No Escape slows enemy energy regen (stopping opposing ultimates), and Malice reduces the crit rate of enemies — a key counter to crit-focused hybrid and shadow builds.
Bjorn (or Attila/Hippo):
- Energy Shield
- Rage Blessing
- Energy Suppression

Bjorn provides bonus magic damage reduction and a 20% bonus to magic damage dealt, stacking yet again onto Merlin’s burst chain. Rage Blessing boosts early regen (pairing well with Arcana and Psionic Tide), while Energy Shield keeps Merlin healthy. If you are using Attila or Hippo, replace Energy Shield with Oaken Guard or Fighting Master depending on opponent types.
Strategic Considerations
Just like earlier seasons, your build must adapt to the enemy teams in your battlegroup. Conquest is filled with players running optimized shadow, hybrid, fire, and chaos setups, so flexing your skill sets is mandatory.
- Misleading: Use against physical-heavy opponents to cause missed normal attacks. Stack this with dodge-based artifacts and talents to create miss-focused defense.
- Malice: Essential in metas with high crit setups like Shadow or Chaos. Reducing enemy crits can often be the difference between surviving a nuke or not.
- Weakness: A key offensive support skill. Boosts your Merlin’s crit potential substantially. A must in this setup unless you are already crit-capped.
Dragon Talent Tree: Water Dragon in Conquest
In Conquest, Dragon Talents become available, and they play a huge role in maximizing your Water build’s effectiveness.
Coalesce is your go-to talent specialization. It amplifies the magic damage dealt by your dragon’s breath and scales further with chill effects. This stacks beautifully with Bjorn, Ragnar, and Arcana, resulting in devastating Merlin ultimates.

If you are still relying on non-Bjorn backlines, Inspiration may be useful instead to boost team energy regen. This is especially valuable if you’re using Hippo/Attila to maintain energy uptime.
Thanks to the elemental flexibility of the Water Dragon, you retain your 4-element synergy bonus even when running Bjorn (a Shadow immortal). This allows you to push a maximum burst setup without compromising your elemental cohesion.
Progression Path & Chaos Meta
Once you hit Conquest, the next step is entering the Chaos meta. If you acquire Chaos Immortals, consider transitioning Merlin into a more frontloaded burst role by using Energy Mastery in place of Psionic Tide.

In Chaos, Merlin becomes the centerpiece of even more refined compositions. Combining Energy Mastery with the rest of your regen and amplification stacking leads to some of the highest frontloaded damage outputs in the game. Merlin effectively becomes a most dangerous AoE caster.
Final Thoughts
Water marches are all about optimizing your damage amplification and protecting Merlin long enough to get his big spells off. With the build outlined above, you ensure fast and frequent ultimates, constant control over the enemy’s abilities, and incredibly high burst damage potential.
If you’ve followed this guide series from Season 1 to Conquest, congratulations — you now have a Water march that can match (and defeat) some of the strongest setups in Infinity Kingdom. Thanks to players like Hastur for contributing meta-defining builds!
