Undisputed + Eye of Reen work really well together on all 3 Sentinel masteries. I’ve been trying something similar to your build tonight, but I use Rebuke instead of Rive, and on my Paladin I use Holy Aura, Sigils, Lunge, Warpath, and Rebuke. Made it to around 190 in arena so far, will probably adjust some things to go further.
I prefer Sigils to Anomaly because they add lots of defense, last longer, and can refresh themselves on kill. They have the option to add some flat fire damage too, but I felt like I needed more defense and stuck with block.
Rebuke works nicely because while making you nearly invincible it refills your mana, works with channeling bonuses on gear if you have them, and gives you a massive attack speed & armor boost at the end of channeling.
I used to run a 2h build instead and made it to wave 198, but this DW setup does exponentially more damage at the cost of defense. I had about 50/50 block/effectiveness with my 2h, and nearly none with this. I think I’ll try out the ignite & Flame Burst nodes in Holy Aura tomorrow, and test the same gear setup on my Forge Knight to see how that does. There’s some interesting bleed and ignite options in both trees, and Divine Bolt + Axe Thrower proc a ton with this setup.
Honestly it’s a shame that 2h damage is so low by comparison. I don’t think a top tier rare or any of the uniques would be a match for this.
