This one started out as an experiment and quickly turned into one of the strongest budget builds I've ever played. The idea was to use Corpsewalker boots as a source of corpses for cyclone cast while channeling Detonate Dead (DD) without requiring desecrate. This lets you use additional damage supports and doesn't cut your trigger rate in half (since normally CwC and CoC linked to multiple spells will alternate which spell gets triggered).

Noteworthy Interactions:

• Corpsewalker boots enables cast while channeling Detonate Dead by continually spawning high level corpses around you.
• 23% quality Anomalous Detonate Dead combined with The Consuming Dark dagger converts 99% of your fire damage to chaos damage. We have 100% chance to poison from the dagger and Divergent Herald of Agony.
• Replica Innsbury Edge allows our cyclone to apply withered on hit, and grants us some chaos leech. A fortify on hit corruption gives us nearly permanent fortify up time while we cyclone.
• Replica Innsbury Edge causes us to take 10% physical damage as chaos damage and Incandescent Heart causes us to take 25% elemental damage as chaos damage. As a CI build, this essentially means we take 10% less physical and 25% less elemental damage.
• We use Yoke of Suffering and apply 5 different ailments to cause enemies to take 25% increased damage. Chill and shock are applied by Corpse Pact from the corpses we spawn, the 1% of DD fire damage we aren't converting to chaos applies ignite, our chaos damage applies poison, and our cyclone has a small chance to apply bleed from jewels.
• All of our damage scaling is generic elemental, chaos, or minion damage (with Spiritual Aid), and thus applies to both the spell portion and explosion portion of Detonate Dead's damage. This, combined with increased corpse life from Corpse Pact and Undertaker wheel on the tree gives us very large corpse explosion damage. It also scales poisons from the explosions without needing to invest in poison-specific scaling.
