Version, purpose and verified scope
Counterattack, Pestilence and Ring of Writhing Moon form the Poison Swarm package. Balazan’s Bite, Arioc’s Needle and Infinity complete the Mythic setup. Ghosts of Odium and its selected lesser powers explicitly belong to this S15 configuration.
Patch family 3.2.3; level 70. Source variant: Mythic. Author revision: 2026-10-06T02:41:15. This page includes the complete skill allocation, bar, equipment, sockets and board/glyph list. Record and top-rank claims in the source title are not adopted as our own measurements.
Skill, item and glyph names retain unambiguous English planner labels. Numbers in the point table are allocated ranks, not final ranks increased by gear.

Stats, tempering and upgrade order
Secure Writhing Moon and the matching set before luxury Runewords. Then optimize Counterattack ranks, DoT/Poison multipliers and resource/cooldown support. The Stinger starter has a different main sequence; do not partially mix its bar with Mythic.
The table lists attributes from the selected source, with preferred Greater/Masterwork targets first. It does not reuse present-day tooltip percentages as historical values.
| Slot | Attribute priority | Tempering |
|---|---|---|
| Helm | Cooldown Reduction · Dexterity · Maximum Life · Armor | Worldly Endurance Maximum Resolve Stacks |
| Chest | Ranks To Counterattack · Dexterity · Maximum Life · Armor | Worldly Endurance Maximum Life |
| Gloves | Damage Over Time Multiplier · Dexterity · Vulnerable Damage Multiplier · All Damage Multiplier | Worldly Finesse Damage Over Time |
| Pants | Dexterity · Maximum Life · Armor · Resistance To All Elements | Worldly Endurance Maximum Life |
| Boots | Dexterity · Movement Speed · Maximum Life · Armor | Natural Motion Movement Speed |
| Weapon | Damage Over Time Multiplier · Poison Damage Multiplier · Movement Speed · Maximum Life | Worldly Finesse Damage Over Time |
| Amulet | Damage Over Time Multiplier · Vulnerable Damage Multiplier · All Damage Multiplier · Ranks To All Skills | Worldly Endurance Maximum Resolve Stacks |
| Ring 1 | Damage Over Time Multiplier · Dexterity · Vulnerable Damage Multiplier · Poison Damage Multiplier | Worldly Stability Cooldown Reduction |
| Ring 2 | Damage Over Time Multiplier · Dexterity · Poison Damage Multiplier · Vulnerable Damage Multiplier | Worldly Stability Cooldown Reduction |
Runes and gems
Sockets for the selected variant. A rune pair belongs together in a suitable item; socketed runes and completed Runeword equipment are different things.

| Pants | Yul + Kry |
| Weapon | Emerald + Emerald |
| Amulet | Splinter Of Hellfire |

Limits and safe transitions
Poison buildup and movement triggers limit brief phases without target contact. The older S13 Evade setup does not describe this build unchanged.
Verify resource sustain, protection and core items together before increasing difficulty. An author’s test with particular gear, density or boss phases does not prove identical performance on every character.
