Version history

Version	Changes
3.22.0	The Delve-exclusive Shield prefix modifiers that provide +3% to maximum Fire, Cold, or Lightning Resistance can no longer roll. (wiki editor notes) This changes probably already implemented in version 3.17.0. This entry in the version 3.22.0 patch notes probably confirming it is intended and not a bug.
3.20.0	The Delve-exclusive Body Armour modifier that grants 10-15% increased Effect of your Curses can no longer roll. The boots mod Hexes have (40-60)% increased Doom gain rate no longer drops. Existing items with this mod in the permanent leagues are converted to (40-60)% increased Damage with Hits and Ailments against Cursed Enemies [Undocumented This change was not documented by any official sources. It was discovered through player testing or datamining.]
3.17.0	Influenced Shield prefix modifiers that grant increases to maximum Resistances have been added to the core Shield modifier pool, and can no longer roll on Influenced Shields. This also affects Delve drop-only variants [Undocumented This change was not documented by any official sources. It was discovered through player testing or datamining.]
3.4.0	Introduced to the game.
