Radiation Melee / Bio Armor Brute — Comprehensive Build Guide

Archetype: Brute · Primary: Radiation Melee · Secondary: Bio Armor · Pools: Fighting, Leadership, Speed · Epic: Mu Mastery

Leveling Order

Plus the free Fitness inherents: Swift (1, unslotted), Hurdle (1, unslotted), Health (2 — Heal x2), Stamina (2 — EndMod x2). Total: 67 enhancement slots, matching the level-50 cap.

Why this slotting

• Contaminated Strike / Radioactive Smash carry Touch of Death and Mako's Bite full — your two most-used Contaminated-setup hits get the accuracy/damage/recharge plus the Lethal-resist and melee-defense set bonuses.
• Devastating Blow / Radiation Siphon get the purple/rare big-hitters (Armageddon, Hecatomb) since they're your heaviest single-target nukes and benefit most from the +Recharge/+Accuracy bonuses.
• Irradiated Ground is the perfect home for Achilles' Heel (3 pieces, exact fit) — a constantly-ticking PBAoE toggle gets the most chances per minute to proc the -20% Resistance debuff.
• Hardened Carapace / Environmental Modification / Evolving Armor (your three resist/defense toggles) carry Aegis, Reactive Defenses, and Gladiator's Armor — stacking Mez Resistance toward the cap and rounding out S/L/Energy resistance and melee/area defense.
• Ablative Carapace / Parasitic Aura share Preventive Medicine for heal/absorb + recharge.
• DNA Siphon gets Panacea for the global +Recovery/+Regen proc.
• Hasten only accepts Recharge (per the live power data) — 2 slots is the standard, no End Discount possible.

Set Bonus Highlights

Stacking from Touch of Death, Mako's Bite, Hecatomb/Armageddon, Aegis, Reactive Defenses, Gladiator's Armor, and Eradication gets you: high uptime recharge (~60-70% global with Hasten), capped/near-capped Mez Resistance, meaningful Lethal/Psionic/Energy resistance layered on top of Bio Armor's native toggle resistance, and Melee/Area defense in the 15-20% range before Combat Jumping or incarnates.

------------------

A few notes on the import:

• This uses the planner's Inherent category for Swift/Hurdle/Health/Stamina, matching how the planner models Fitness as auto-granted rather than a normal pool pick — their levels in the text are cosmetic, only the enhancements matter.
• Adaptation (level 10) is the pick that grants access to all three Bio Armor forms; the importer auto-derives the hidden Defensive/Offensive/Efficient toggles, so they don't need separate lines.
• After importing, default to Defensive Adaptation while leveling and switch to Offensive Adaptation for farming/AoE content — it's a free instant toggle swap, not a separate purchase.
• If any enhancement fails to resolve (the importer will flag it with a warning), it's almost certainly a level/set-range mismatch — Touch of Death tops out at 40, Achilles' Heel at 20, Eradication at 30; everything else here is valid through 50.
