Our take on Thraex Harness

“The griffin guards the patient”

“The griffin guards the patient”: only the Gladiator can block, so only Gladiators should wear it. Its block line is actually larger than Murmillo’s Steel (+5%), but Murmillo adds finisher damage, which usually wins.

What does the Thraex Harness set bonus do?

+6% Block strength

Makes your block stronger. Only the Gladiator can block (the class card says “Block: 70% less damage”), so this line is wasted on other classes.

+7 Vitality and +35 Max HP

On our level-1 Gladiator with 124 Max HP, the set’s +35 Max HP alone would be a 28% increase. Every set adds flat health that scales with rarity. Uncommon sets give +7 Vitality / +35 Max HP, against +5 / +25 for Common and +11 / +55 for Rare.

How do you get the Thraex Harness pieces?

Uncommon gear can also come from chests. These are the chests that can roll Uncommon items:

A chest that rolls Uncommon still picks one item from every Uncommon armor and weapon, so a specific piece of Thraex Harness is much rarer than the Uncommon chance.

Who should use Thraex Harness?

  • Gladiator (sword and shield): +6% Block strength.

How to build around Thraex Harness

Gladiator (sword and shield). Pair it with the Gladiator’s block (70% less damage) and the Scutum path: Iron Skin adds +4% Max health per rank, and the capstone Unbreakable cuts damage by 20% below 35% health. Hold block through boss wind-ups and counter with the slash, backhand and shield bash chain.

Fit: our reading of the bonus Based on the class cards and skill tree we saw in game, not on damage tests.
