Top 20 Monsters by Gold & XP

These are the most rewarding regular (non-boss) monsters per fight. Values assume no gold/XP boosts from heroes or premium. Corrupted variants of each monster yield an additional 50% gold and XP but have higher stats.

TIP

Corrupted versions of rank 7–14 monsters (Death Knight through Sea Leviathan) offer the best risk-adjusted gold/XP per stamina. They spawn at the same locations but have red health bars and grant +50% rewards.

Boss Monsters (IDs 181–190)

Boss monsters have unique IDs, multiple combat phases, and exclusive loot tables. They appear at specific dungeon floors or as named world encounters. Each boss has a fixed weakness and may apply unique status effects.

Boss ID Name Location Level Phases Weakness Exclusive Drop

WARNING

Bosses with 3+ phases enrage at 20% HP, increasing their ATK by 50% and gaining immunity to stun. Do not attempt ID 187–190 without full endgame gear and a high-loyalty hero active.

Corruption Modifiers

Any monster in categories 2–11 can appear as a Corrupted variant. Corrupted monsters have a red aura, significantly increased stats, and grant bonus rewards. The Corruption system spreads every 6 hours from active Corruption Zones (see World Events).

Corruption Tier HP Modifier ATK Modifier DEF Modifier Gold Bonus XP Bonus Drop Rate Bonus
Tainted (Tier 1)+30%+20%+10%+25%+25%+10%
Corrupted (Tier 2)+60%+40%+25%+50%+50%+20%
Defiled (Tier 3)+100%+65%+40%+100%+100%+40%
Abyssal (Tier 4)+180%+100%+60%+200%+200%+75%

Corruption zones can be cleansed during the World Invasion event. Cleansing a zone grants bonus Corruption Tokens, which are exchanged at the Corruption Vendor for exclusive cosmetics and set items.

Race-Specific Weaknesses

Certain damage types deal bonus damage to specific enemy races. This is separate from elemental weaknesses and stacks multiplicatively with them.

Silver Damage (vs. Vampires)

Any weapon with a Silver base deals +35% bonus damage to all Vampire-type enemies. Silver weapons are crafted by Werewolf players with the Blacksmithing profession at level 5+. Vampires fighting Vampire enemies receive no silver bonus — this applies only cross-faction.

Holy Damage (vs. Undead & Demons)

Holy skills and Holy-enchanted weapons deal +40–60% bonus damage to all Undead (Cat 8) and Demon (Cat 9) enemies. Holy enchantment is available via the Priesthood faction at Honored rank. Both vampire and werewolf characters can use Holy enchantments.

Bleed & Poison (vs. Aberrations & Dragons)

Category 10 (Dragons) and Category 11 (Aberrations) are resistant to most elemental damage but uniquely vulnerable to Bleed (+30%) and Poison (+25%). Werewolf Berserker subclass applies Bleed on critical hits by default, making it highly effective against endgame content.
