Hi, how are you operator? I'm here to update this with the latest releases. This is an extremely comfortable and simple build to play as it is easy to understand, has most mods accessible and no legendary arcana, but I am aware of those who will want to improve this or you can find other ways to play with [Atlas] here in overframe.com.

Frame Mods:

• Rejuvenation: The Atlas need be healed to accumulate rubble so this mod help Adaptation on external health by Quick Thinking.
• Adaptation + Quick Thinking: Adaptate and multply healty on external points by energy pool.
• Primed Flow + Nourish: Multiply energy pool by 5x or 505% with staked Molt Augmented.
• Molt Augmented: Increase Nourish and Landslyde total damage.
• Arcane Guardian: More armor points to aproximate the passive of 90% damage reductions87% exactly.
• Purple Archon Shards 5x: 185% critical damage and double damage bonus on landslide skill, this is more damage than strength shards / mods. (I'm not sure but this is equivalent to 500% bonus damage divided into 5 virtual hits but ignores all critical modifiers.)

Frame mods notes:

• Molt Augmented increase Nourish tath increase spam of skill 4 to accumulate rubble but can be replaced by Arcane Fury to increase instant damage on melee.
• Arcane Guardian can be replaced by Arcane Reaper tath gives you more health but this forces you to play more carefully.

Melee chose:

• Sibear Incarnon Genesis: This is one of the best melees for landslide because the last evolution adds +25% critical chance based on Atlas landslide, that is, this +25% will be added to [Atlas]' innate 5% and these numbers interact with any critical chance mod and combo multiplier.

Melee Incarnon Evolutions:

• 2nd Master's Shetter: hitting enemies affected by cold adds 10 points to the combo counter helping to quickly accumulate combos, cold procs can be generated by comppanion, the best weapon for this is Hellstrum.
• 3rd Orokin Reach: +1 range for melee, we're not going to waste mod slots with range so this is the best choice to improve common moves and Tennokay.
• 4th Absolute Value: +25% critical chance added directly to the landslide skill which will interact with critical chance increase mods and combo counter.

Melee Mods:

• Sacrificial Pressure + Sacrificial Steel: passive damage and critical chance to landslide and melee common hits.
• Blood rush + Gladiador Might: 600% critical chance on landslide while the melee combo counter is at 12x.
• Gladiador Might + Organ Shatter: 150% critical damage on melee base critical.
• Healing Returne: Auxiliate survivor and adaptation on common hits.
• Primed Fever Strike + Volcanic Edge: this is gas damage to make temporary damage clouds. yet another damage variant taking into account that Melee Exposure already deals 240% corrosive damage, you dont need viral damage because Nourish provide this, you cant make toxine to copus faction because this goes make viral decrasing Master's Shetter.
• Melee Exposure: Corrosive damage on landslide, Very powerful against infested enemy resistant to status effects.

Melee Notes:

• Melee Exposure just add corrosive damage on melee after skill use, be careful.
• You can choose other melee incarnon genesis with the same evolution 4th Absolute Value, note tath Sibear Incarnon Genesis add +25% critical chance while Ceramic Dagger Incarnon Genesis add +30%, my main choice for Sibear is thematic to increase my fashion frame gameplay.

Aditional Weapons:

Boar Incarnon Genesis has high status chance and impact damage to trigger Primary Exhilarate, this sinergizes with Nourish.
Bronco Incarnon Geneses has a augment mod Dissyng Rounds tath open enemies to finisher and mercy.
Helios has a melee and can trigger Vicious Bound, this could be your main armor removal skill on single targets.
Nautilus can equipe Hellstrum and Shiverig Contagion, this is great to apply AoE cold status and increase Master's Shetter has Cordon precept mod, this can group enemies to common melee attack.
