High Priest Apocalypse build: MVP, raid and PvP

High PriestAs of 13 October 2026 (SEA, Lv.90, Apocalypse Season 1)

High Priest plan for Lv.90 and Apocalypse Season 1 in SEA: a Continuous Heal healer for Calamity Zone raids and PvP, and a Holy Magnus build with Swift Exorcism for MVPs. Armor sets, cards, special skills, Starcore traits and runes for each mode.

Our take

The RO New World team's own view

Pick High Priest if you want the most wanted seat in Calamity Zone. On Taiwan's server, healers were the class raid parties were short of. Build the Holy Magnus side only as a second weapon, for MVP hunting.
First get a Royal Survival Wand V with Continuous Heal and red Healing Light, then the Goibne Set III and two Kind Heart III. Raise Guard to 80, then 160, before anything else. The Magnus staff (Royal Advanced Survival Wand III with Swift Exorcism) comes after that.
The biggest trap is building a healer like a mage. Magic damage bonus does not raise heals, so the Angel Set and Mistress's +15% add nothing to them. Purgatorial Angel is worse: it cuts Heal, Sanctuary and Coluseo Heal by 80%.
Our verdict: one Continuous Heal staff covers both the raid and PvP, so it is the best value Apocalypse weapon for the class. Swift Exorcism is a strong second weapon: Magnus gets +30% against 12 of the 24 MVPs and 4 of the 5 raid bosses.

Key findings

Heals use M.ATK, not magic damage

In a Taiwan test, magic damage bonus did not raise healing. In the game text, Heal, Coluseo Heal, Sanctuary and Continuous Heal all scale with M.ATK. So a healer wants M.ATK%, Healing% and armor that keeps them alive. The Angel Set, Mistress Card and Ranged MDMG% are for the Magnus build only.

Continuous Heal almost doubles Coluseo Heal

At red quality, Continuous Heal adds 100% M.ATK per second for 10 seconds to every target of Coluseo Heal. That is 1,000% M.ATK on top of the 1100% M.ATK + 720 of the cast itself. Red Healing Light cuts the 20-second cooldown by 5 seconds, so the heal over time runs 10 of every 15 seconds.

Magnus fits 4 of the 5 raid bosses, but needs its own staff

Magnus Exorcismus gets +30% damage against Demon, Undead, Shadow and Undead-element targets: Pharaoh, Bloody Knight, Dark Lord and Anubis, and 12 of the 24 MVPs. Apocalypse traits stay on the item they are on, so Continuous Heal and Swift Exorcism mean two weapons. Taiwan players name priests as one of the classes this costs the most.

Armor

Wear Goibne to heal, Angel to deal damage

Each set has 3 pieces: armor, cape and shoes. The set bonus works only with all 3, so don't mix pieces. Because heals ignore magic damage bonus, a healer's set should keep you alive: Goibne for the raid, Elemental for PvP against casters. The Angel Set is for the Magnus MVP build only.

Goibne Set III

Best

Best for the raid healer

Set: Wind, Earth, Water and Fire skill damage taken -5%, VIT +6, Max HP +800, P.DEF +20
Each piece: VIT +6 and HP. The armor adds VIT +1 and Max HP +0.6% per refine level
Best for: a healer who must live through the big hits. A dead healer means a wipe

Elemental Set IV

Option

Best for PvP against casters

Set: Wind, Earth, Water and Fire skill damage taken -5%, Max HP +3%
Each piece: Wind, Earth, Water and Fire damage taken -5%, plus -0.6% per refine level
Use: PvP and Siege, where enemy wizards and element skills do most of the damage

Angel Set II

Option

Best for the Magnus MVP build

Set: INT +5, DEX +5, magic damage +2.5%
Each piece: magic damage +2.2%, plus +0.4% per refine level
Use: only for Magnus Exorcismus and Judex damage. It does nothing for heals

Odin Set III

Option

Bigger heals in a safe party

Set: STR +6, INT +6, ATK +2%, M.ATK +2%
Each piece: ATK +1.4%, M.ATK +1.4%. Armor adds INT +1 per refine; cape and shoes add DEX +1 and VIT +1
Use: when nobody is dying and you want more healing per cast. M.ATK raises every heal

Values are for Royal pieces from the game data; Royal also adds HP. Orange pieces have the same set bonus.

II · MVP hunting

MVP build: Holy Magnus

Holy · Swift Exorcism

For solo or small-party bosses. Two Magnus Exorcismus crosses under the boss plus Judex do the damage, and Purgatorial Angel makes them much stronger. Half of the MVPs are Demon, Undead or Shadow, where Magnus gets +30%.

Stats

INT

Max it first. All your damage scales with M.ATK

DEX

Until Judex casts fast. Suffragium already cuts variable cast time by 30%

VIT

The rest. Purgatorial Angel weakens your own heals, so you need HP

Swift Exorcism

Magnus Exorcismus DMG interval -0.05~0.23sRed quality: Magnus Exorcismus damage interval -0.23s. Magnus hits every second for 14 seconds, so this is about 30% more hits from every cross.

How to play

Learn Purgatorial Angel for this build: Magnus Exorcismus +300% and Judex +100%, but Heal, Sanctuary and Coluseo Heal -80%. Bring another healer for hard MVPs.
Cast B.S Sacramenti first so Suffragium is up, then two Magnus crosses under the boss (up to 2 at once), then Judex.
Magnus gets +30% against Demon, Undead, Shadow and Undead-element targets: 12 of the 24 MVPs. Skip Angeling, which is Holy itself.
Use Lex Aeterna before your biggest hit: the next damage the target takes is +100%.
