Damage engine and purpose
Mammoth Hydra retains old Etched Sigil. After unrestricted S20 categories end, normal slot priorities and Teleport replace Orb/Furnace.
Item, skill and rune names use their English game spelling for unambiguous lookup. Explanations, rotation and limitations are fully translated.

Legendary and normal gems
Legendary gems: Enforcer / Legacy of Dreams / Taeguk.
Normally use an Emerald in weapon sockets; choose the helm socket for cooldown or Life needs. Match armour sockets to missing main stat or toughness. Seasonal Soul Shards replace helm or weapon gems only in the explicitly identified seasons.
Stats, cooldowns and optimisation
Fire, Hydra, Intelligence and protective shields. Maintain the channel for Deathwish; do not assume the later Winter Flurry/Fragment signature loop.
Complete the required legendary powers, correct runes and full set bonuses first. Cooldown reduction combines multiplicatively; do not simply add percentage rolls. Weigh a boss gem against a farming gem according to actual boss-fight length.
Rotation: preparation, damage, refresh
Step 1
Activate Storm Armor/Magic Weapon and place Hydra ahead of the pack.
Step 2
Use Black Hole and channel Arcane Torrent for old Etched Sigil/Deathwish.
Step 3
Teleport before danger, refresh Karini from range and reposition Hydras.
Patch boundaries and verifiable context
This is an explicitly editorial adaptation of the dated S20 bar to S21’s normal Cube categories. Only already available powers are used.
From S22 Etched Sigil specialises in Energy Twister; this archive then switches to the separately dated Typhon signature profile.
Check before the next equipment change
Count set pieces before replacing a free armour slot. Equipping and cubing an identical legendary power does not double it. Solo Unity requires a follower wearing the other ring with immortality equipped.
This archive describes the period configuration. A current item database may show new numbers under the same name; those live tooltips do not prove historical multipliers. Old seasonal powers cannot be replayed on current non-seasonal characters.
