GRIM DAWN / SYSTEM
Monster Infrequents (MIs)
A Monster Infrequent (MI) is gear dropped only by a specific monster (or a specific family of monsters). Its base stats are fixed - only the prefix and suffix roll randomly. Many carry mastery-skill bonuses (+n to skills), making them irreplaceable by legendaries for some builds. Target farming - identifying the dropper and hunting it repeatedly - is a core endgame loop, and since v1.2.0.0 every boss drops its own MIs (excluding legendary-tier MIs) at 100%, so the hunt is about which affixes roll, not whether the item drops.

DO THIS FIRST
- ▸Spotting an MI: it's green gear with a fixed dropper, usually carrying the enemy's or location's name (e.g. Cronley's Signet drops only from Darius Cronley).
- ▸Want a specific MI? Look up its dropper first (search procedure below), then loop that enemy's location, remaking the session each lap.
- ▸Affixes are RNG: since the base is fixed, the real hunt is rolling good prefixes/suffixes - a mediocre roll still works as a stopgap.
- ▸Want certainty? Since v1.2.0.0 bosses drop their own MIs (excluding legendary-tier) at 100%, Nemeses included - and Nemesis MIs always roll at least one Rare affix (spawn conditions in Legendary Farming Basics).
- ▸For which MIs your build wants, see the gear/farming sections of the individual build pages.
01 / MI-DEFINITION
What an MI Is and Why It Matters
- ▸An MI drops only from its designated monster - some from exactly one enemy, others from a specific family or lineage.
- ▸The base item's stats are fixed, with random prefixes/suffixes layered on top - the same MI varies hugely with its rolls.
- ▸Many MIs carry specialized bonuses like +n to mastery skills, making them irreplaceable by legendaries for builds built around specific skills.
- ▸They span every level band - from the early Cronley's Signet to endgame Nemesis MIs.
02 / MI-VS-RARE
MI versus Ordinary Rare (Green) Gear
- ▸Ordinary rare (green) gear uses generic bases that can drop from anything, with the base itself also random.
- ▸An MI differs in having a unique base and a fixed dropper - being farmable on purpose is the whole point.
- ▸Since v1.2.0.0 all bosses drop their own MIs (excluding legendary-tier MIs) at 100%. Nemeses follow the same rule rather than being an exception, and since v1.1.7.0 Nemesis MIs always carry at least one Rare affix.
- ▸Vendoring rule: badly-rolled MIs can be sold, but stash good rolls of the MIs your build depends on (see Mid Game Money).
03 / TARGET-FARMING
The Target-Farming Procedure
- ▸The procedure: 1) look up the MI's dropper, 2) confirm where that enemy spawns and how to reach it, 3) loop from the nearest rift, killing it and remaking the session each lap.
- ▸The stop condition is rolling affixes that fit your build - what counts as 'good' is build-dependent, so use your build page's recommended affixes as the bar.
- ▸For hero/boss droppers, memorize the shortest path from the nearest riftgate to keep laps tight.
- ▸Drop rates and lap counts are RNG - no guarantees.
04 / SEARCH-PROCEDURE
Looking Up the Dropper
- ▸Searching an MI's name in the Grim Tools item database shows its dropper (Japanese display is supported).
- ▸Conversely, the monster database lists each enemy's notable loot.
- ▸Grim Tools is an external browser DB - it can't be queried in-game, so look things up and note them before farming.
- ▸Our build pages also list each build's target MIs and farming spots.
