Passive: Damage scales with Movement Speed; losing stacks on hit hurts DPS
Unlock: Defeat 1,000 Skeletons
Default Weapon: Bone
Role: Speed DPS / Kiter
Recommended Weapons: Boomerang (speed-friendly multi-hits), Aura (passive damage while kiting), Axe (boss-focused single-target)
Tomes (order): Agility → Cooldown → Quantity → Size/Duration
Beginner Preset: Aura + Boomerang; Agility → Size → Regen → Cooldown
High-Curse Preset: Agility → Cooldown → Quantity → Armor/Shield; play hitless to preserve stacks

Core Mechanics & Gameplan

More speed equals more damage. Keep runs hitless, take Agility early, then uptime stats (Cooldown/Quantity).

Weapons & Upgrade Path

Boomerang — benefits from speed pathing and returns
Aura — lets you farm without stopping to aim
Axe — dedicated boss tool when waves are under control

Tome Priority & Why

Agility — core scaling for both DPS and safety
Cooldown — increases uptime on all weapons
Quantity — extra hits from every projectile
Size/Duration — extends AoE and return arcs

Step-by-step Route

Phase 1 (0–4 min) — Stabilize clear/survivability; grab your core Tome #1 and at least one crowd tool.
Phase 2 (4–8 min) — Finish main weapon upgrades; lock in Tomes #2–#3; start boss DPS plan.
Phase 3 (8+ min / Boss) — Cover weaknesses (shield/armor/evasion), add burst or DoT as needed; align cooldown windows for boss.

Mistakes to Avoid

Greeding damage before wave-clear/safety is online.
Ignoring shrine tempo and pot routes.
Overcapping one stat (e.g., Crit or Move Speed) at the expense of Quantity/Cooldown.

Presets (Details)

Beginner — Take survivability items and play wide circles; level Aura while learning hitless movement.

High-Curse — Cap speed early, then layer defenses and a boss nuke; never trade hits—your DPS vanishes when hit.

Notes

Avoid greed looting that breaks your speed lines; route through shrines and pots cleanly.
