You play a triple-class character, so the game balances your power by letting enemies multi-class too. Crank a zone's difficulty from D0 up to D4 and the fights get brutal, but the loot drops pre-upgraded, all the way to +4.
D0 through D4 is an instance difficulty system: you set how hard a dungeon or zone runs. Higher tiers turn ordinary mobs into layered threats and, in return, hand out dramatically better loot.
Because your character fuses three classes, the game answers by letting enemies do the same. The higher the tier, the more likely each mob rolls a second and third class, gaining their health pools, heals, and tricks.
The payoff: loot drops at the upgrade rank of the tier you run. D0 drops base gear, D4 drops +4 gear, with a diminishing chance to roll even higher. That is a colossal head start on the road to +10.
| Tier | Enemy multi-classing | Enemy stats | Best for |
|---|---|---|---|
| D0Baseline | 100% single-class | Standard HP, damage, and aggro radius | Fast leveling and pure XP |
| D1–D2 | Rare dual-class (roughly 10 to 30%) | Moderate bump to HP and damage | Balanced leveling and a solo challenge |
| D3 | High chance of dual or triple-class | High HP, expanded aggro radius | Group progression and gear upgrades |
| D4Extreme | 100% guaranteed triple-class | Massive HP pools, high damage, fast movement | Endgame farming for +4 gear |
On D0 a Befallen skeleton is just a Necromancer or a Warrior. On D4 every mob rolls three random classes. When trash picks up Cleric, Paladin, or Shadow Knight, it gains complete heals, Lay on Hands, stuns, and spell interrupts. A random mob that heals itself or stuns you mid-cast sends its time-to-kill through the roof.
Higher tiers scale up melee damage, damage mitigation, and spell resistance, and they widen aggro range, both proximity and social "friend" aggro. On D3 or D4 a single bad pull can drag an entire room down on top of you.
Gear in EQL merges and upgrades to +10. D0 drops base +0 items; D4 drops pre-boosted +4 items, plus higher-tier motes as difficulty climbs. Because each upgrade rank is worth far more than the last, a +4 drop is a massive shortcut, community estimates put it as much as 16 times more efficient than fusing base gear up yourself.
