Overview
Bonestorm Oracle is a ranged physical-spell caster that relies on control and automatic triggers rather than a single carry skill. Bonestorm is the main damage source, Entangle roots enemies in place, and two Cast on Critical setups fire off Thrashing Vines and Thunderstorm for extra physical and lightning damage while the player keeps casting.
The build’s strength is its layered damage in long fights: Sigil of Power marks a zone for tougher encounters, and every triggered spell adds to the pressure Bonestorm already applies. Mana Remnants keeps resources stable, and the control from Entangle and vines gives the Oracle a safer feel than more aggressive casters.
The creator rates bossing as its standout at 5/5, while mapping is described as safe and tactical rather than a pure zoom clear.
Pros & Cons

Cons
- Needs crit chance for Cast on Critical to trigger consistently
- Feels slow if cast speed, crit or mana sustain are under-invested

Gear & Anointments
Priorities are spell damage, physical damage, critical chance, cast speed, mana sustain, area of effect and cooldown recovery, followed by defensive layers. Specific uniques and anointments to be confirmed against the source video; a full written guide is linked in the video description.

Endgame Notes
On bosses, place Sigil of Power during safe windows, keep Entangle active and cast Bonestorm continuously so the triggered spells keep firing. The creator rates league start 4/5, bossing 5/5, mapping 4/5 and scaling 5/5.
