Monster modifier

✍️This article is a stub. Please help improve the article by expanding it.

Monsters can have modifiers which increase their danger and rewards.

Explicit modifiers

Magic monsters and monster minions can have up to one affix; rare monsters have 2-4 affixes. It is possible to increase the number of affixes further or apply them to unique monsters through certain Atlas passive skills or modifiers. Each additional modifier grants the monster increased item rarity and quantity.

When monster modifiers are stolen by players (e.g. through Behead, Headhunter, Ritual Sacrifice, etc.) the stats the modifiers grant to players may be different than the stats they grant to monsters.

Version	Changes
0.2.0	Monster Modifiers stolen from Rare Monsters, such as through Behead Support, have had the effect they provide to players adjusted to be more appropriate. Increased the chances for Rare monsters to have 3 or 4 Modifiers in Maps (note this means they drop more items). This is mostly to compensate for the removal of rare monsters granting their modifiers to other rare monsters on death. Added a series of enhanced Rare Monster Modifiers that are more powerful than the standard versions and more rewarding. Some rare monster modifiers now scale at later levels, providing better rewards. The "Powerful Minions" modifier has been reduced in power to compensate for the above.
0.1.1	Volatile Plants are now much more noticeable both before and as they're about to explode. Elemental explosions caused by minion death or those periodically cast by a Rare Monster have had their visual effects improved. The delay before these explode has also been increased. The Aura from the "Prevents Recovery Above 50%" Monster modifier now has a visible radius. Energy Shield modifiers on Monsters now provide far more sensible levels of Energy Shield.
0.1.0e	The 'Siphons Flask Charges Modifier' on Monsters now drains ten-times less Flask Charges per second. (This was unintentional). Disabled the Volatile Crystals Modifier, to be revised in the future pending telegraphing improvements. The Trail of Fire monster Modifier now deals 30% less Damage and lasts for 3 seconds (from 5 seconds). The Trail of Lightning monster Modifier now lasts for 4 seconds (from 8 seconds). The Trail of Ice monster Modifier now lasts for 4 seconds (from 8 seconds). The Purple Explosives created by the Volatile Plants Modifier on Rare Monsters now deal significantly less Damage.
0.1.0d	Reduced the defences provided to monsters by the Magma Barrier modifier.
0.1.0c	Monster Modifiers now grant higher amounts of Item Rarity and Item Quantity. This is most common on Magic and Rare enemies, but also affects Unique Enemies if applied through various Endgame Mechanics like the Deadly Evolution Keystone. (Doubled rarity bonus per mod, +10% quantity per mod) Increased the chance for Rare Monsters in Maps to have 3 or 4 modifiers.
0.1.0	Introduced to the game. (Hotfix 7) Reduced the amount of energy shield monsters gain from the Rare Modifier "Extra Energy Shield"
