Build:Inquisitor

Full Build Details
Counter-based build.

Run into the enemy and bait them to attack you.

Catching anyone in Brace will get them to 50% impact so you can wail on them with impunity (including Unknown Arena bosses).

Trade in minimum points to unlock mana.

Enchant Iron Claymore with Unsuspected Strength for Tsar-level damage but higher attack speed (although physical damage, so resistances apply). Alternatively, use Prayer / Sinner Claymore with Redemption for more lightning-based build (but this option does not give infinite durability of Unsuspected Strength).

Enchant Scavenger Scarf with Unassuming Ingenuity. Alternatively, use Scholar Circlet with Rain (or Arcane Unison) - this will free Leyline Connection breakthrough for Shamanic Resonance or Well of Mana. You will starve for mana without constant regen consumables tho (even more so with Arcane Unison), and lose +50 badass look points that scarf gives.

Enchant Caged Armor Boots with Flux.

Enchant Pearlescent Mail with Aegis.

Enchant War Bow with Enkindle.

Suggested enchants require only simple incense (alternatives require advanced incense).

Can switch Preservation Backpack for Light Mender's Backpack to get +10% lightning damage.

Can switch Cannon Pistol for Cage Pistol, but that will leave you with War Bow and Pommel Counter as your sources of Confusion.

With minimal mana and fast regen mana burn from sleeping isn't a problem since you can restore the maximum with couple of cycles of Divine Light Imbue upkeep.
