Implicit modifier is the effect above the line separating modifiers.
Note that enchantments use their own modifier slot to the item and will not replace implicit modifiers. Synthesised have different implicit modifiers from the original base item, up to three.
PoE 3.21: Added a new HasImplicitMod Condition for item filters, which can be used to filter by items that have at least one implicit modifier.
The implicit modifiers on equipment can be by altered in various ways:
On items, visible implicit modifiers are most commonly found on:
Shields and body armour also commonly have a hidden movement speed penalty modifier.
Certain unique items also have special interactions with implicits:
Implicit modifiers always spawn on entities before the addition or change of additional modifiers (for example by changing the rarity).
On monsters, implicit modifiers can be very commonly found. For example, some monsters are granted damage conversion which converts their inherent damage to that of another element. However, on unique monsters and bosses implicits are most notable – for example most bosses are granted a boost to their item rarity and item quantity as well as other bonuses such as on Atziri.
