Acid Aegis of Menhir Sentinel

An active attack that hurls the shield at a target, staggering it, before it returns to hand. Taking 1 point in the Aegis of Thorns modifier converts 100% of its Fire damage to Acid and adds 18% of the character's Retaliation Damage value to the attack (RAtA). The Ronaprax's Sting amulet adds another +22% RAtA specifically to Aegis of Menhir, for 40% combined. This bonus applies whenever the skill is used, regardless of whether you're currently being hit — the shield's block and high physical resistance are a separate, purely defensive benefit. Bind the Dryad devotion's Dryad's Blessing proc here.

The Occultist's primary attack: a homing projectile that streaks toward the target and detonates for acid/poison damage. Bind Manticore's Acid Spray proc here.

A curse that lowers enemy defensive ability and resistances. Bind Murmur's Rumor proc here to stack additional resistance shred.

An Occultist defensive buff. Bind Behemoth's Giant's Blood proc here for an on-hit emergency heal.

A buff granting sustained regen and Vitality Decay resistance.

An Oathkeeper self-buff granting damage absorption — save it for when you get surrounded and things get dangerous.

A defensive Oathkeeper aura, invested alongside Haven — max both together to shore up survivability.

A support node unlocked while investing in the Oathkeeper mastery bar; per the source guide, take 1 point here and 1 in Summon Guardian of Empyrion as prerequisites. The summoned guardian's own attacks can trigger bound devotion procs, so bind Abomination's Abominable Might proc to Summon Guardian of Empyrion.

• ▸Start as Occultist and lean on Dreeg's Evil Eye. Weapon type doesn't matter — just swap in whatever rolls better damage/physical resistance as you find it.
• ▸After defeating Warden Krieg, head to Old Arkovia and join the Forgotten Gods' Cult of Dreeg faction. Pick up the early MI amulet, Ronaprax's Sting, which adds +90% weapon damage and +22% Retaliation Damage to Attack, both specifically to Aegis of Menhir.
• ▸Farm Sister Crimson, Vengeance of Kymon in the Tomb of Sethan (Valley of the Chosen) for Chosen Raiment and Korvan Pauldrons.
• ▸Buy Vine Ring from the Vinelton vendor in Ancient Grove for both ring slots, and reset-buy Hyram's shop in Malmouth until a physical-resistance-rolled Colossal Defender appears.
• ▸Farm the Guardian of Dreeg near Devil's Crossing for Dreeg-Sect Legguards. Fill gloves/boots with whatever easily-farmed rare/MI armor covers your resistances for now.

• ▸Keep Ronaprax's Sting as the amulet (+90% weapon damage and +22% Retaliation Damage to Attack, both on Aegis of Menhir specifically). Weapon type doesn't matter, so use whatever rolls best; keep a physical-resistance-rolled Colossal Defender as the off-hand shield.
• ▸Hold onto Chosen Raiment (chest), Korvan Pauldrons (shoulders), and 2x Vine Ring.
• ▸Gloves: Mythical Viperfang Grips is BiS; use easily-farmed budget armor for resistances until you get it.
• ▸Waist: Gargoyle Girdle — a rare item, but its all-Retaliation-Damage bonus scales up both Aegis of Thorns' and Ronaprax's Sting's RAtA cuts.
• ▸Legs: Dreeg-Sect Legguards. Helmet: fill resistances with any easy rare/MI piece, or chase Dreeg Venomshroud Hood for its acid/poison/vitality damage bonuses.
• ▸The source guide doesn't name specific medal/relic picks — choose ones with acid damage bonuses individually.

• ▸Hold your shield and rapid-fire Dreeg's Evil Eye for steady acid/poison damage.
• ▸Open on packs with Curse of Frailty first to strip resistance and DA before committing.
• ▸Weave in Aegis of Menhir throws too (Acid via Aegis of Thorns) — RAtA permanently adds 40% of your Retaliation Damage value to it, a flat bonus independent of whether you're currently being hit. Taking hits is still useful for farming the Dryad's Blessing and Giant's Blood procs, but don't just stand still — keep some distance and reposition.
• ▸Pop Ascension when surrounded and things get dangerous.

Curse of Frailty plus the Murmur and Manticore devotions strip enemy acid/poison resistance and DA. On your own side, build around Colossal Defender's physical-resistance roll and Gargoyle Girdle's Chaos resistance, filling the rest to cap with components and augments. Carrying a shield also gives block mitigation on top of resistances.

This isn't a mindless AFK tank — it plays closer to a caster (the source guide explicitly says it's "not for lazy facetankers"). Watch out for early threats like Alcedian Aldrick's stun attacks in Act 2 Elite. The guide is from v1.2.0.3 and hasn't been re-verified on the current v1.2.1.6.

Farm Sister Crimson in the Tomb of Sethan (Valley of the Chosen) for Chosen Raiment and Korvan Pauldrons, the Guardian of Dreeg near Devil's Crossing for Dreeg-Sect Legguards, gargoyle packs for Gargoyle Girdle, and Hyram's shop in Malmouth for Colossal Defender.
