James' Viper Strike Gladiator

Bringer of Rain 15% block for legacy
The Anvil 10% block on legacy
Rive 15% block for dual wielding these
The Red Nightmare Putting this in the Marauder Jewel slot can give up to 14% block

Getting all of these gear pieces would cap you at 78% block and spell block

Shaper's Touch This will scale your DEX into more survivability
Growing Agony You will need 4 of these to scale your damage

In your Bringer of Rain, you want Viper Strike > Melee Splash > Rapid Decay > Multistrike (it already gets Melee Damage and Faster Attacks)

You want to grab as much DEX on gear as you can, as it will benefit you in HP, melee damage, evasion, accuracy, and bleed damage. Any pieces of gear that aren't used for uniques should be +50 DEX, assuming your resistances are capped. Remaining Jewels should be +% damage/+%HP/DEX
