Alright. You want the hands-down scoop on the Revenant?

It was designed as a facetanking healer class. Playing it as a DPS factory is incorrect. It feels strange at first, though- you have to switch between builds/styles to stay maximally effective, depending on what you're doing (tagging/heal tanking/boon ripping), but it's very good at all of these things. My guildies and I have been completely blown away with how well this build performs, extending fights, keeping party hp up, recovering from miscues, and mitigating projectile output. I'm convinced that it can solo almost any content in the game, if you're willing to wait a few hours to get through a health bar (Candy Corn Viscount took ~1 hour, I say ~1 hour because I got kicked out of the instance after 45 minutes and he was at ~25% health) while keeping up with your micros.

I'll go over each type/style here with a build link. BUT FIRST, you need to know the sacred precepts of the Way of the iPad.

I) Always Bring Your iPad

Select the Ventari legend. Take some time to get used to that centaur face looking up at you from your quickbar. It is not going to leave you from this point onward. This is your core mechanic. You are part of the Brotherhood of the iPad now. Unless you're underwater. Obviously. Because iPads aren't waterproof and Dorfs can't swim. Dummy.

II) Learn to Juggle Your iPad

Summon your iPad. Activate it again. Oooh, look! You can zoom it around. That's nifty. Practice keeping it with you when you run, shooting it ahead of you so it passes through you while you walk. For bonus points, learn to trigger your heal charge/burst skill before moving the tablet so that you get the heal effect while running.

Once you have that down, practice with some friends in a dungeon. Try to hit as many party members as possible with it while fighting. It's trickier than it sounds. You aren't always necessarily going to do this (if you're using Nourishing Roots instead of Tranquil Balance or Blinding Truths), but you need to know how to do this for the rest of this to make sense.

III) Stop Worrying and Learn to Love the Baton

Your melee weapon is invariably going to be staff (unless you've unlocked herald, in which case I think you want mace/shield, but I haven't yet, so I haven't tested this). I'm running a Magi staff Water Purity.

There are a couple reasons for this:

1) Glowy Orbs

Every third hit, you'll drop three glowy orbs that heal, grant regen, and give swiftness when they're walked over.

2) Cleansing Bolts

If you turn on your iPad's reflect and connect with a staff auto, you'll unleash a flurry of cleansing bolts.

3) Cleave

The autoattack is a lunatic whirly cleavy tornado straight out of a majorette's baton-twirling wet dream. You're going to hit people behind you, in front of you, and everywhere else. Damage isn't important, getting that third chain attack in is.

IV) Do the Centaur Shuffle

Since you've embraced the staff as your lord and savior, you are ready to master the art of the Centaur Shuffle. Go into your options menu and set an easily accessible button as your action camera key. When you're in melee, you're going to want to turn this on, and just hold down your autoattack key. Then, make a gentle sweep back and forth. Not a lot. You're basically trying to spread your Glowy Orbs evenly in the stack and walk over orbs you've made to add to your effective hp through mitigation (you only pick up orbs if you need them).

V) Tap That (Natural Harmony Key)

You've made it this far. Only a little way to go now. Natural Harmony is your best friend. Get used to hammering on it whenever you see your party's HP bars drop. It has a channel, but you can start the channel and it will keep channeling while you move the tablet (it doesn't get interrupted). You can use this to drop a double heal on someone by channeling and setting it to move through them in quick succession. With practice, you'll be able to time the heal to burst right as the tablet heal triggers from moving through them. You can also put up a reflect around the tablet and move it to protect someone who's gotten knocked out of position.

VI) Be Fashion Forward

You'll need a full set of Magi armor (I use exotics, and I'm up to fractal level 50ish with just trinkets ascended backpiece). I think Zerker trinkets are fine. I'm running those mostly, and it seems to work fine, though I might be getting some more specialized rings.

I'm using Runes of Altruism, but Runes of the Monk are on my list- just haven't had the time to farm AC.

VII) Hammer On

Get a Zerk hammer for farming/roaming. I have mine slotted with Benevolence Venom, though I really want to get Transference runes, I just have no idea where to get them.

VIII) Be Racist

All Kung Fu warriors eat rice. You should too. Buy a few stacks of delicious rice balls before the price goes up. 10% outgoing healing effectiveness is hard to get anywhere else for the price. The Halloween custard (hp/second xp) is nice to have on hand for times where you need to focus more on keeping yourself up than keeping others up.

VI) Know Your Modes

Your utility legend trait line is extremely important. You won't do too much fiddling around with the Salvation and Invocation lines, but the other line will change depending on what you want to do in a given situation.

Your Modes:

1) Buffalo Billionaire Mode (Roaming/Farming)

Specialty: Tagging mobs, doing reflects and healing.

Weapons: Hammer/Staff

Utility Legend: Shiro

Utility Traitline: Retribution

Weapon Quirks: Use hammer 2 to tag (the aoe is huge). Use hammer 4 to fill in reflect gaps. Use hammer 5 to chip break bars.

Legend Quirks: Use Impossible Odds to keep up with zergs, and pop your healing skill before you swap back to iPad. The blades persist through the switch, and give you free heals dps.

2) Stripper Mode

Specialty: Stripping boons from enemies and conditions from allies.

Weapons: Hammer/Staff

Utility Legend: Mallyx

Utility Traitline: Corruption

Weapon Quirks: None. Your job is to close to melee ASAP, so just have the hammer for some ranged options in an emergency.

Legend Quirks: This is the hardest one to do properly. You'll need to practice fights to get a feel for which phases need which legend. The timing usually goes

MALLYX ->

HAMMER ON BANISH ENCHANTMENT ->

POP ULT TO BURN OUT REMAINING ENERGY ->

iPAD BEFORE BURN PHASE IS OVER ->

HAMMER ON NATURAL HARMONY ->

IF CONDIS ARE OUTSTRIPPING YOUR iPAD HEAL ->

iPAD ULT then MALLYX ->

HAMMER ON PAIN ABSORPTION TO CLEAR YOUR PARTY'S CONDIS ->

MALLYX HEAL ONCE YOU'RE DROWNING IN CONDIS ->

REPEAT

3) Man Mode

Specialty: Laughing in the face of death. Sexually identifying as a brick wall.

Weapons: Hammer/Staff (Though you could put in swords or mace sword here as well- up to you).

Utility Legend: Dorf

Utility Traitline: Retribution

Weapon Quirks: None. Your job is to close to melee ASAP, so just have the hammer for some ranged options in an emergency.

Legend Quirks: This is for when you need to step up and hard tank. You've ideally got a healer, and your job is to take a million billion damage. I haven't run into a situation where this was necessary, but it may come into play in raids. It's also fun to use this build to experience the satisfaction of taking massively telegraphed attacks to the face without going down. You've dumped all your altruistic traits in favor of self-preservation in the face of death.

Key trait changes are:

1) Using [Blinding Truths] instead of [Nourishing Roots] or [Tranquil Balance], turning your tablet juggling into a 2 second cd aoe blind.

2) Using [Natural Abundance] instead of [Selfless Amplification]. This pops an ult fragment out of your iPad every time you do anything with it. The more you shuffle and faceroll on your keyboard, the more you heal (1342 per pickup).

3) Using [Improved Aggression] instead of [Close Quarters]. This doubles the duration of your taunts and gives you 20% damage reduction against taunted foes.

4) Using [Eye For an Eye] instead of [Dwarven Battle Training]. This helps you passively break break bars and mitigate incoming conditions with protection. I'm not 100% sure if this is better than [Dwarven Battle Training], though.

Basically your job is to get in close, taunt, turn on your whirling axes with their damage reduction, and maintain taunt and axes until you're full of condis or you're almost out of energy. Once that happens, pop your heal, switch to iPad, faceroll yourself back to health while blinding the enemy, then swap back to Dorf once you're healthy and it's off CD. Rinse and repeat.

Edit: Before anyone asks, I forgot to get exact healing numbers.

Glowy Orbs: ~700

Natural Harmony: ~1200-~2100

Tablet Skillshot Heal: ~1400

Self-Heal/s- ~65-~315

Ult Orb Heal- 4x~1800

Plus effective healing from Stripper Mode.
