Hi, Rudy here, back with another Delve build! This is trauma-stacking Boneshatter featuring Pyroclast and Stormblast mines with 500% aura effect.

PoB: https://pobb.in/drrF96WuvBbv (480m burst dps, config set to 550 trauma, focus on, berserk on)

Character profile: Rudy_Unstoppable

Build is entirely dependent on having mines out to do any dmg. Build features a lv 35 Pyroclast mine for all of its base fire dmg, and a lv 1 Stormblast mine for increasing dmg taken by enemies. Key breakpoint is 500% aura effect (400% increased), which we get from crucible trees (150% inc x2), and the rest being generic aura effect nodes on tree/gear/gems. We invest in aura aoe (aura radius: 53 units), mine duration (11 sec mines), and mines cannot be damaged mastery.

For full dps, we need to throw 2 sets of each type (10 mines each), which takes about 2 secs total. And they need to be refreshed every 12 secs or so. Note that most delve nodes are time-gated, so its fine in most cases to not throw mines at the start, and do zero dps, while ramping up with perma-berserk and attack mastery.

Trauma-stacker Jugg's defences are well known by now, so I'll just list the key differences from my 3.19 Self-curse Boneshatter:

• --- Mantra of flames, which used to give 4000-8000 base fire dmg. Losing this made the build infeasible since 3.20.
• ++ 10x Pyroclast Mines, giving 2400 base fire dmg. This dmg is flat unlike Mantra, so you do much more dmg at low trauma (below 300), and lower dmg at high trauma (above 600)
• ++ 10x Stormblast Mines, inflicting 150% increased dmg taken on enemies.
• --- Self curse Temp Chains, which used to give 40s trauma stacks, and 14s immortal calls.
• ++ More duration investment. Currently at 17s trauma stacks, which cap out at a maximum of ~650 stacks with the helm enchant.
• ++ Attack mastery that gives 5% IAS per nearby enemy, is incredible. This makes the ramp-up much faster than before.
• ++ 10% of armour applies to chaos dmg. Makes the build like 5-10x tankier vs chaos dmg, which used to be a weakness in 3.19.

The build is a very strong delver, but with the mine management, its not the easiest build to play. It does get much easier with practice though.
