List of drop-restricted Delve modifiers

These special modifiers can appear during delving in the Azurite Mine.

Modifiers are found in specific thematic delve nodes that Contain X Items:

• Fire: Redblade Retreat/Redblade Base, Sweltering Burrow, Restless Rubble (fire golems),
• Cold: Mutewind Retreat/Mutewind Base, Frigid Recess, Restless Rubble (ice golems),

• Physical: Nesting Grounds
• Chaos: Renegade Camp, Restless Rubble (chaos golems).
• Minion and Aura: Grim Copse, Necromancer's Excavation, Beast Burrow

The devs removed shields with above mods from the Delve node drop pool in version 3.17.0, as these mods have equivalents in the shield mod pool. However, the current versions of these mods that can be rolled are suffixes.

of the Underground	Suffix	CurseEffectiveness	60	(10-15)% increased Effect of your Curses
Subterranean	Prefix	AllDamage	60	(40-60)% increased Damage with Hits and Ailments against Cursed Enemies

The devs removed the above mods in version 3.20.0 due to the Doom / Hex re-work. Existing items with the mod (40-60)% increased Damage with Hits and Ailments against Cursed Enemies have had their function changed from Hexes have (40-60)% increased Doom gain rate in this patch.

Name		Stats
Subterranean	60	0.4% of Physical Damage Leeched by Enemy as Life
Subterranean	60	0.4% of Fire Damage Leeched by Enemy as Life

The above mod can only be crafted via flipping the Delve drop-only mod in the Reflecting Mist, which is not (yet) added to the core game since the end of Kalandra leagues.
