This exclusively a mapping build capable of every map mod (including T-17s), every eater altar, delirium, beyond, and other difficulty map scaling options. Note: It is not a boss killing character, but can kill some bosses in T-16s, especially with the aid of Vaal Breach.
The Scavenger Blunderbore node allows us to forgo life and AoE in the tree. The permanent Massive shrine it grants is a 20% maximum life buff, which can be scaled via shrine effect. We use shrine effect idols and The Gull helmet to try to maximize this interaction.
Similar to the self-ignite chieftain build of past, Scavenger lets us forgo the required staff it uses. The scavenger Fulcrum node allows our ailments to be self reflected. Ignite is made 'unaffected by' via the Forbidden Flesh/Flame scion jewels. Shock is negated by Tempest Shield. Chill is reversed by Winterweave ring. Freeze is negated by Arctic Armor. Since there will be a reflected ignite on us (that deals no damage to our character b/c of Chieftain jewels) we can now proliferate ailments from our character as it moves.
The Scavenger Zerphies Heart node is selected to make the Obliteration wand explosions (25% corpse life as chaos) apply ailments. Rashkaldor's Patience amulet makes it so that no investment is needed to apply all elemental ailments. The ailments are then proliferated via Fan the Flames cluster node and Shock Proliferation influence implicit on gloves. The damage of the explosion is also scaled from idol effect and the Brutal Shrine buff interaction, making the explosion do of 100%+ of monster life as damage.
Defenses are 75/78 block, 60% phys taken as fire w/ 90% fire res, endurance charges, adrenaline, and immortal call during mapping. The PoB life number is not accurate compared to the video (you can see how much the idol stacking adds to life) There are no other config settings in the PoB except for a custom mod to represent the shrine effect.
Lots of room to take the build better and spend more currency.
