Nanobots are the utility swarm slot: skill cooldown reduction and passive HP regeneration. They do not add damage — they add uptime, and uptime is what skills-based builds actually scale on.
Every wearable drops with a power level from 1 to 10; its stats scale linearly with power, so a power-5 item gives exactly half the values below. Higher-level monsters and boss kills roll better power.
| Item | Stats at power 10 |
|---|---|
Scout Swarm | Cooldown Reduction +18%, HP Regen 0.5 HP/s |
Venom Cloud | Cooldown Reduction +8%, HP Regen 2 HP/s |
Frost Mist | HP Regen 2.8 HP/s, Cooldown Reduction +2% |
Shield Hive | HP Regen 1.5 HP/s, Cooldown Reduction +10% |
Ember Shroud | Cooldown Reduction +20% |
Storm Aura | Cooldown Reduction +12%, HP Regen 1.5 HP/s |
Shadow Veil | Cooldown Reduction +15%, HP Regen 1 HP/s |
Plasma Field | Cooldown Reduction +18%, HP Regen 0.5 HP/s |
Blood Fog | HP Regen 3 HP/s |
Void Haze | Cooldown Reduction +10%, HP Regen 1.5 HP/s |
Ember Shroud (-20% cooldowns) effectively buys you extra casts of every skill you own; Frost Mist (2.8 HP/s regen) is the sustain pick.
