Charms: Small, Large and Grand Charm Affixes, Skillers and Unique Charms

How charms work in Diablo 2 Resurrected, the most wanted charms and where they drop, every magic affix that can roll on Small, Large and Grand Charms (with value ranges, required levels and affix levels) and how to get the unique charms. Includes the Warlock skillers added in Reign of the Warlock.

1.How Charms Work

Small Charm1 × 1 inventory space Large Charm

Large Charm1 × 2 inventory space Grand Charm

Grand Charm1 × 3 inventory space

Charms only work while carried in the inventory and identified; they do nothing in the stash or inside the Horadric Cube.
There are three sizes: Small (1×1), Large (1×2) and Grand (1×3). The same affix rolls higher on a bigger charm but takes more space, and some affixes only appear on the bigger sizes.
A magic charm has at most one prefix and one suffix. Charms cannot be rare, crafted or socketed; unique charms are a separate kind.
The affix level decides which affixes can roll: an affix can appear when its affix level in the tables is at or below the charm's affix level. That is derived from the item level (the level of the monster that dropped it): on a Grand Charm it equals the item level, on a Large Charm it is 7 lower and on a Small Charm 14 lower, and the gap closes at very high item levels.
A charm's required level is the highest required level among its affixes.
You can reroll a magic charm's affixes in the Horadric Cube with 3 Perfect gems + the magic item — see the Horadric Cube guide.

2.Highest Values by Size

The highest value each size can roll, with the required level for that value in brackets. "—" means the stat does not roll on that size.

3.Most Wanted Charms

The magic charms players hunt to fill their inventory. Names are the in-game (and trade) names; stats show the top tier. In the Level column the first number is the required character level, the second the lowest level the dropping monster must have for that tier to roll (item level) — where to find it is in the next section.

Small Charms

Charm	Stats (top tier)	Level	Best for
Shimmering Small Charm of Vita	All Resistances +3–5, +16–20 to Life	39 / 61	Everyone: resistances and life in one slot
Fine Small Charm of Vita	+10–20 to Attack Rating, +1–3 to Maximum Damage, +16–20 to Life	39 / 61	Physical melee and bow builds ("3/20/20")
Serpent's Small Charm of Vita	+13–17 to Mana, +16–20 to Life	40 / 62	Casters short on mana
Ruby Small Charm of Vita	Fire Resist +10–11%, +16–20 to Life	39 / 61	Topping up one resistance (Sapphire, Amber or Emerald instead of Ruby)
Shimmering Small Charm of Good Luck	All Resistances +3–5, 6–7% Better Chance of Getting Magic Items	33 / 61	Magic finding

Grand Charms

Charm	Stats (top tier)	Level	Best for
(Skiller) Grand Charm of Vita	+1 to one skill tree (skiller), +41–45 to Life	83 / 91	Characters of that class; the most valuable Grand Charm
(Skiller) Grand Charm of Balance	+1 to one skill tree (skiller), +12% Faster Hit Recovery	42 / 50	Casters chasing a faster hit recovery breakpoint
(Skiller) Grand Charm of Inertia	+1 to one skill tree (skiller), +7% Faster Run/Walk	42 / 50	Extra run speed
Sharp Grand Charm of Vita	+49–76 to Attack Rating, +7–10 to Maximum Damage, +41–45 to Life	83 / 91	Physical melee (instead of a skiller)

Value per slot: the best life roll is 20 on a Small Charm (1 slot), 35 on a Large Charm (2 slots, 17.5 per slot) and 45 on a Grand Charm (3 slots, 15 per slot). That is why most of the inventory goes to Small Charms, Grand Charms are carried mainly for skillers, and Large Charms are rarely chosen.
A skiller with a suffix (life, FHR, FRW) is worth far more, but a bare skiller is still useful.
The most wanted unique charms are Annihilus, Hellfire Torch, Gheed's Fortune and the sunder charms; how to get them is further down.

4.Where Charms Drop

Magic charms have no special source; ordinary monsters drop them too. The level of the monster that drops the charm decides which affixes can roll: item level = monster level.

Ordinary monsters are at the area level; champions are 2 levels higher, unique and super unique monsters 3 levels higher. Act bosses have fixed levels (table below).
In level 85 areas the highest item level is 88 (unique monsters); outside bosses the highest is 90 (Arreat Summit, Colossal Summit).
Terror Zones (Hell only): monster level builds on the higher of the area level and the character level — ordinary monsters +2 (up to 96), champions +4 (up to 98), uniques and bosses +5 (up to 99). This is where the highest item levels come from.

Item Level Needed

Target	Lowest item level	Where
Skillers (Grand Charm)	50	Nightmare Acts IV and V and most of Act III; anywhere in Hell
The best life, mana, MF, resistance and 3/20/20 rolls on Small Charms	61–62	In Nightmare only the last Act V areas (Ancients' Way, Arreat Summit, Nihlathak's Temple, Worldstone Keep) and the Secret Cow Level; anywhere in Hell
Sunder charms (unique)	69	Hell Terror Zones (elite monsters)
Gheed's Fortune (unique)	70	Almost anywhere in Hell; in Nightmare only a few bosses such as Baal (75) and Nihlathak (70)
+36–40 to Life on a Grand Charm	77	Anywhere in Hell Acts III, IV and V; the higher areas of Acts I and II
+41–45 to Life on a Grand Charm	91	Level 85 areas are not enough. Only Nihlathak (92), Diablo (94), Baal (99), Terror Zone monsters and the Uber bosses
The strongest damage affixes on Small Charms (Jagged, of Craftsmanship, Flaming, Pestilent, Red, Hibernal, Shocking)	90–95	Terror Zones and the highest level bosses (Nihlathak 92, Diablo 94, Baal 99)

Level 85 Areas (Hell)

The highest level areas outside the bosses and the best places to farm charms. A number in brackets marks an area that is not level 85.

Boss Levels

A boss's level is the item level of what it drops. Uber Diablo (Diablo Clone), the Pandemonium Ubers and the Colossal Ancients are level 110.

Boss	Normal	Nightmare	Hell
Andariel	12	49	75
Duriel	22	55	88

8.Skill Charms (Skillers)

These Grand Charm prefixes give +1 to one skill tree of one class; players call them "skillers". All of them have required level 42 and affix level 50. The same charm can also carry a suffix such as life, faster hit recovery or faster run/walk. The bonus only helps a character of that class. The Warlock's three skillers arrived with Reign of the Warlock.

9.Unique Charms and How to Get Them

You can carry only one of each unique charm. The stats of the sunder charms and the Latent/Renewed versions from Reign of the Warlock are in the Unique Jewelry, Charms and Jewels guide.

AnnihilusSmall Charm Hellfire Torch

Hellfire TorchLarge Charm Gheed's Fortune

Gheed's FortuneGrand Charm

Annihilus — Uber Diablo (Diablo Clone)

Annihilus only drops from Uber Diablo, and killing him always drops it. Uber Diablo is a level 110 copy of Diablo with a huge life pool and fast regeneration.

Online: Stones of Jordan sold to vendors in games of your region are counted. Progress is announced in six stages starting with "Terror gazes upon Sanctuary"; at the last stage "Diablo has invaded Sanctuary" appears and Uber Diablo spawns in the Hell games of that region.
Offline (single player): selling a single Stone of Jordan to a vendor in Hell difficulty is enough.
Uber Diablo replaces the first super unique monster you meet (for example Corpsefire in the Den of Evil or Bishibosh in the Cold Plains), so you can choose where he appears.
Because he regenerates, Open Wounds and high fire and lightning resistance are recommended.

Hellfire Torch — Pandemonium Event (Uber Tristram)

A three-stage chain; every stage is done in Hell difficulty and the portals are opened with the Horadric Cube in Act V Harrogath. It also works in single player. The recipes are in the Horadric Cube guide as well.

1. Keys — three super unique monsters occasionally drop a key; one of each key type is a cube recipe.

Key	Dropped by (Hell)
Key of Terror	The Countess — Forgotten Tower (Act I)
Key of Hate	The Summoner — Arcane Sanctuary (Act II)
Key of Destruction	Nihlathak — Halls of Vaught (Act V)

2. Mini Ubers — cubing the three keys in Harrogath opens one of three portals at random. The same portal does not open twice in one game, so opening all three needs nine keys (three of each).

Portal	Boss	Drops
Matron's Den	Lilith	Diablo's Horn
Forgotten Sands	Uber Duriel	Baal's Eye
Furnace of Pain	Uber Izual	Mephisto's Brain

3. Uber Tristram — cubing the three organs in Harrogath opens the Uber Tristram portal. Kill Uber Mephisto, Uber Baal and Pandemonium Diablo; the last one to die drops the Hellfire Torch and the Standard of Heroes Standard of Heroes.

The Torch's +3 goes to the skills of a random class; since Reign of the Warlock that is one of 8 classes, the Warlock included. You may need several runs for the class you want.
Uber Mephisto's Conviction aura cuts resistances hard, and the Ubers regenerate quickly, so Open Wounds is close to mandatory.

Gheed's Fortune — Normal Drop

There is no special source: it can drop as a unique Grand Charm from any monster of item level 70 or higher (required level 62). That level is found almost everywhere in Hell; in Nightmare only a few high level bosses (Baal 75, Nihlathak 70) reach it. Magic Find improves the chance, and the vendor discount also makes it valuable for gambling.

Sunder Charms

The six sunder charms (Black Cleft, Bone Break, Cold Rupture, Crack of the Heavens, Flame Rift, Rotting Fissure) break monster immunity to one damage type. They drop from champion, unique, super unique and boss monsters in Hell Terror Zones (item level 69+).
Reign of the Warlock: the Latent versions drop more often from Heralds, tiered boss enemies that appear as you kill monsters in a Terror Zone, and can also come from other monsters in Hell. A Latent charm is turned into a Renewed one in the Horadric Cube with a Perfect gem, a rune and Worldstone Shards — see the Horadric Cube guide.
Worldstone Shards drop from elite monsters in Hell (champions, uniques, super uniques, act bosses). Right-clicking one turns every area of its act into a Terror Zone for the rest of that game.

10.Data Source

Values follow the Diablo 2 Resurrected 3.3 (Reign of the Warlock) game data. The game files also contain a +46-50 life tier for Grand Charms, but its affix level is 110 (the maximum is 99), so it never drops normally and is left out of the tables. The same files list a "Lucky" prefix with Magic Find for Large and Grand Charms, but it has no required level and never drops; Magic Find only rolls on Small Charms.
