My build is still coming together (lv86, just starting empowered monos) but it’s a true melee build and I use all 5 buttons. TL;DR version: Rive + auto-Hands, Judgement to spend, lunge+shield slam, dmg-scaled aura. Everything scales through melee dmg, strength, phys/fire, and healing effectiveness. I use all 5 buttons on bosses and all but the stun clearing packs.
Lunge (specced for cooldown recovery, heal, and fire conversion)
Judgement (specced for manaspend and attack damage, no spell component)
Shield Bash (unspecialized slot, could be any other utility, the stun helps skip boss attacks I can’t just heal through)
Holy Aura (specced for crit/damage)
Rive (main attack skill, you can pretty much spec this to taste, I have it on 1-2-1-2-3 with ignite scaling, pull on 2, and more dmg stacked on 3)
Healing Hands (not on bar but specced into an attack w/ autocast on melee hit and damage, be sure to get the Virtue of Patience node near the bottom right since the cast speed penalty has no effect when you only use it as a proc on hit)
Rive is my spammable/mana recovery attack, clears most packs on its own. Judgement is my spender for burst damage. Aura is mainly damage scaled so just pop it against tough rares/bosses, time it against bosses to make sure you can afford to spam judgement as much as possible and don’t have to dodge a telegraphed attack. Shield slam should be saved to interrupt strong boss windup attacks at the last moment. Lunge is almost never on cooldown except when traversing empty areas by lunging at crates.
Passive tree is pretty standard - all the 1 point wonder block chance nodes, healing effectiveness and ignite > str > other dmg scaling, not needing any of the flat spell dmg nodes frees up room for the movespeed one at the end of pally and a decent splash into VK for some crit multi.
Defenses are a bit sketchy without Exsanguinous/ward shenanigans but anything that doesn’t oneshot me or empty my health bar within ~1 second I can just heal through by attacking. With exsang it can become extremely tanky thanks to healing hands converting to ward. Also lots of room to squeeze more damage out of it with good +skills gear, IIRC every damage skill I use has some %more dmg nodes in reach.
If you don’t like the feel of Rive, any other melee 0mana could work in its place (other than spin2win, channeling attacks don’t keep proccing healing hands so the build falls apart). If you don’t feel like you need the stun, you could sub in shield rush for traversing long straightaways with no enemies to lunge at, or volatile reversal bc instacast heal to full is pretty good. sigils don’t do much unspecced but you could spec that instead of lunge if you wanna fit it in. Another big change you could pretty easily make would be using a 2H weapon and taking the double +dmg effect on 2H node for Rive - losing block would prob make Exsanguinous/ward abuse almost mandatory but maybe stacking good endurance gear would be enough? You could def push the damage much higher that way. You’d obviously have to either swap out shield slam (or spec it over lunge and get the no shield required node) but nothing else needs a shield to work.
Top gearing priorities are a good +healing hands helm, as much attack speed as possible for moar healing hands procs, and healing effectiveness (it pulls double duty scaling hands with flat dmg and making all the small heal effects you can get from passives actually heal a meaningful amount). Block and endurance are good options for scaling survivability. If you can get your hands on an Exsang with some LP, you can become almost unkillable thanks to the interaction with healing hands and the absurd rate you can proc it.
