UUID	UUID
Amount	Double	May be positive or negative.
Operation	Byte	See below.

The operation controls how the base value of the modifier is changed.

0: Add/subtract amount
1: Add/subtract amount percent of the current value
2: Multiply by amount percent

All of the 0's are applied first, and then the 1's, and then the 2's.

Entity Effect

Packet ID	State	Bound To	Field Name	Field Type	Notes
0x72	Play	Client	Entity ID	VarInt
			Effect ID	VarInt	See this table.
			Amplifier	Byte	Notchian client displays effect level as Amplifier + 1.
			Duration	VarInt	Duration in ticks. (-1 for infinite)
			Flags	Byte	Bit field, see below.
			Has Factor Data	Boolean	Used in DARKNESS effect
			Factor Codec	NBT Tag	See below

	The following information needs to be added to this page:
	What exact effect does the blend bit flag have on the client? What happens if it is used on effects besides DARKNESS?

Within flags:

0x01: Is ambient - was the effect spawned from a beacon? All beacon-generated effects are ambient. Ambient effects use a different icon in the HUD (blue border rather than gray). If all effects on an entity are ambient, the "Is potion effect ambient" living metadata field should be set to true. Usually should not be enabled.
0x02: Show particles - should all particles from this effect be hidden? Effects with particles hidden are not included in the calculation of the effect color, and are not rendered on the HUD (but are still rendered within the inventory). Usually should be enabled.
0x04: Show icon - should the icon be displayed on the client? Usually should be enabled.
0x08: Blend - should the effect's hard-coded blending be applied? Currently only used in the DARKNESS effect to apply extra void fog and adjust the gamma value for lighting.

~~Factor Data~~

Name	Type	Notes
padding_duration	TAG_INT
factor_start	TAG_FLOAT
factor_target	TAG_FLOAT
factor_current	TAG_FLOAT
effect_changed_timestamp	TAG_INT
factor_previous_frame	TAG_FLOAT

+=== Clientbound ===
+==== Cookie Request (play) ====
-By default, the Minecraft client adjusts the volume of sound effects based on distance. The final boolean field is used to disable this, and instead the effect is played from 2 blocks away in the correct direction. Currently this is only used for effect 1023 (wither spawn) and effect 1028 (enderdragon death); it is ignored on other effects.
+Requests a cookie that was previously stored.

-Formatting: The formatting of a team defines how the names of the team members are visualized. The following table lists all the possible formattings.
+{{Need Info|What exact effect does the blend bit flag have on the client? What happens if it is used on effects besides DARKNESS?}}
+Within flags:
+* 0x01: Is ambient - was the effect spawned from a beacon?  All beacon-generated effects are ambient.  Ambient effects use a different icon in the HUD (blue border rather than gray).  If all effects on an entity are ambient, the [[Entity_metadata#Living Entity|"Is potion effect ambient" living metadata field]] should be set to true.  Usually should not be enabled.
+* 0x02: Show particles - should all particles from this effect be hidden?  Effects with particles hidden are not included in the calculation of the effect color, and are not rendered on the HUD (but are still rendered within the inventory).  Usually should be enabled.
+* 0x04: Show icon - should the icon be displayed on the client?  Usually should be enabled.
+* {{change||0x08: Blend - should the effect's hard-coded blending be applied?  Currently only used in the DARKNESS effect to apply extra void fog and adjust the gamma value for lighting.}}
