This guide covers Baium’s key mechanics, recommended party composition, gearing requirements, and step-by-step tactics to defeat him efficiently and maximize your rewards.

1. Preparing for the Baium Raid

Before facing Baium, your party must meet a few essential requirements.

1.1 Recommended Level & Gear

Minimum Level: 65–70

Optimal Level: 70+

Gear Requirement: Blue +4 or Purple Gear recommended

Crystals: Full set of enhanced Soul Crystals or Magic Defense Crystals

Since Baium deals heavy lightning and magic damage, prioritize upgrading:

Magic Defense

HP and Resistance

Anti-Shock accessories or runes

1.2 Essential Consumables

Bring plenty of:

HP potions (Greater HP recommended)

Defense / Magic Protection scrolls

Attack & Crit scrolls

Soulshots / Spiritshots

Resurrection scrolls

Purification items for debuff removal

If your clan provides raid buff scrolls, use them—it makes the fight significantly easier.

2. Recommended Party Composition

A well-balanced raid team is crucial.

Suggested Setup (15–30 players):

1–2 Knights/Tanks – to hold Baium’s aggro and survive his melee combos

4–8 Healers – essential for surviving lightning bursts

6–12 Ranged DPS (Archers / Wizards) – best for consistent damage while avoiding melee danger

2–4 Melee DPS – optional but useful for burst phases

Support Classes (Bards, Buffers) – provide AoE buffs and debuffs

Ranged DPS is king in this fight due to Baium’s punishing close-range attacks.

3. Baium’s Attack Patterns & Phases

Baium has three main phases, each introducing new mechanics and deadlier attacks.

3.1 Phase 1 – Awakening (100% → 75%)

Mechanics:

Strong single-target hits

Occasional lightning bursts

Random-target shock strikes

Strategy:

Tanks hold aggro at the center platform. Ranged DPS spreads out. Healers stand at the edges to avoid splash damage.

3.2 Phase 2 – Storm Tyrant Awakens (75% → 40%)

Mechanics become more dangerous:

Large AOE Thunder Crash

Chain Lightning that jumps between players

Baium flies into the air briefly during storm shifts

Strategy:

Spread out to avoid chain lightning jumps

Move out of large AOE telegraphs immediately

Healers must stay reactive—burst heals are critical during Thunder Crash

This is where most raids fail.

Mechanics:

Massive lightning storms covering large areas

Baium enrages, increasing attack speed

Tank-buster melee combos

Random-target lightning spears

Strategy:

Tanks rotate defensive cooldowns

Ranged DPS stands at max distance

Assign healing groups for each quadrant
