Rich Text

This gear requirements for UVH6 for this build are low but it does greatly appreciate 70 Specialization Ranks.

Pure Melee, hold a bladed maliwan shotgun with a high fire dot. Sweet Embrace is target farmable. Stellium is best dot + blade. Mantra is ok too.

Armored TUVH6 bosses take some sweaty strats but can be done. Equip a furnace with as much in Raging Inferno as possible, farm a mantra with shooty gun and legs. throw them while doing your forgeskill/punch/repkit/crit knife rotation OR replace a slippy and make sure you forgeskill after every punch. The 2nd option is slower and youll nuke yourself without practice, but easier to get the gear for.

Gameplay

Sword. Puch. Sword. Punch. Fish. Sword. Punch. Sword.

As long as enemies die inside of your Pyroclast storm and you keep swinging Stormcutter youll stay in Onslaughter. But even if you dont Slippy and Fists of Stone will let you keep spamming Stormcutter so youre never without Onslaughter for long.

SWITCH TO FURNACE, PROTEAN CELL, AND THERMAL DIFFUSION FOR BOSSING!!!!!

Furnace - big damage

Protean Cell - big damage and multiple hits for Forgeskill to maintain Onslaughter better

Thermal Diffusion - Big damage, look for Turtle Parts on Protean Cell

Equipment

Weapons

Repkit & Ordnance

Utilities

Viking with as many points in Fists of Stone as possible for mobbing. Furnace works but you need to throw a lot more slippies and the damage isnt needed.
Furnace with as many points in Raging Inferno as possible for bossing

Watts 4 Dinner for mobbing
Protean Cell for bossing

Slippy for better Forgeskill regen

Crit Knife for better boss DPS

The holy grail of Mantra for this build is high fire dot with a blade and a shooty gun with legs tediore reload. You can throw it while doing your bossing to simulate having a Viking on despite having a Furnace on. This is only cool for extended fights on TUVH6. You can ignore this need by simply playing on UVH6.
