How Bonestorm Works
Channeling:
Bonestorm is a channeling skill where you continuously channel to conjure a swarm of bone spikes. While channeled, the skill gathers energy, which is then released when you stop channeling to fire the projectiles at nearby enemies. This makes the skill flexible, allowing for sustained damage while actively engaging in combat or allowing you to target specific enemies.
Physical Damage:
Upon release, Bonestorm fires a number of bone spikes that deal physical damage to enemies. The damage per spike ranges from 16 to 25 Physical Damage, which can scale with your damage modifiers and the number of projectiles fired.
Debuff for Additional Damage:
Enemies hit by Bonestorm are debuffed with a special effect. The debuff causes them to take additional physical damage from the next attack they receive. This effect lasts for 10 seconds, making Bonestorm an excellent setup skill for follow-up attacks that can exploit this debuff to deal massive damage, particularly when combined with other hard-hitting attacks like Heavy Strikes or Projectiles.
Power Charge Synergy:
Bonestorm becomes even more powerful with Power Charges. For every Power Charge consumed, the bone spikes fired during Bonestorm will cause much larger explosions, amplifying the AoE damage and explosion radius. This makes Bonestorm especially effective for builds that focus on Power Charge generation, as you can maximize the skill’s potential to clear large packs of enemies or deal heavy damage to single targets.
Shrapnel Effect:
When the bone spikes hit enemies, shrapnel from the spikes lodges in the enemy, causing them to take additional physical damage from subsequent attacks. This adds a synergistic effect with other attacks, encouraging you to follow up with additional damage-dealing abilities after triggering the Bonestorm explosions.
Maximizing Bonestorm’s Effectiveness
Power Charge Generation:
Since Bonestorm benefits from Power Charges, it’s important to maximize Power Charge generation in your build. Power Charge generation can come from gear, passive skill tree nodes, and support gems like Power Charge on Critical Strike. The more Power Charges you can generate, the larger and more impactful the explosions triggered by Bonestorm.
Follow-up Attacks:
Bonestorm creates an excellent opportunity for follow-up attacks due to its debuff on enemies. Once enemies are hit with the skill and debuffed, subsequent attacks (including projectile or melee skills) can exploit the additional damage the enemies will take. Skills like Heavy Strike, Barrage, or Fireball (if you are mixing elements) can all benefit from the debuff left by Bonestorm.
AoE Enhancement:
Bonestorm is an AoE skill that can be made even more devastating with AoE modifiers. Consider investing in AoE damage, radius enhancements, and increased area of effect through your passive tree or support gems to maximize the reach of your spikes. This will ensure you hit as many enemies as possible with each cast, enhancing both the physical damage and the shrapnel effect.
Mana Management:
Bonestorm has a mana cost of 10.8 Mana per second while channeling, so managing mana regeneration is important. Consider using mana regen support gems, mana cost reduction, or mana leech to sustain your Bonestorm channeled duration and prevent running out of mana mid-fight. This will allow you to continue channeling for longer durations and maximize your damage output.
Critical Strike Synergy:
Bonestorm has a 15% critical strike chance, which opens up interesting synergy with critical strike builds. If you are focusing on critical strikes, consider pairing Bonestorm with critical strike chance or critical strike damage support gems. This can significantly boost the explosion damage and make the skill even more devastating against bosses or elite monsters.

Conclusion
Bonestorm is a highly versatile channeling skill in Path of Exile 2 that combines physical damage, AoE explosions, and Power Charge synergies to create a potent weapon for Witch builds. The skill’s ability to fire bone spikes as projectiles and debuff enemies for additional damage makes it an excellent choice for crowd control and high DPS. By incorporating Power Charge consumption and following up with critical strike or AoE damage, Bonestorm can become a central element of your build’s arsenal. With the right adjustments to mana management and Power Charge generation, Bonestorm can be a devastating tool in both boss fights and map clearing scenarios.
