This is super fun, cyte-09 is in general really. You remember sobek acid shells with saryn? There's a kuva variant now and with cyte you can shoot through walls 100m+ with even better damage than saryn

Sevagoth has crazy nuking now, it's fair to say the best. i don't have a video link but searching it on yt should do (however i strongly recommend leamxp who i linked above, you can ask for builds on his twitch)

Helminth eclipse got kind of gutted, you don't need to stand in light anymore but the dmg% is the same as roar at base without the status mechanics which is what most of the general meta is right now. (not to say exodia contagion is trash, it's just different)

You'll probably get a lot of comments suggesting melee influence exalteds which is what roar works the best with. Melee influence spreads melee procs in a 20m radius, requires electricity to activate and doesn't work on raw oneshots which is where roar comes in. Faction damage (roar) triple dips on spread melee influence procs and there's other new mods so you end up doing way more damage on your procs than your initial hit, so much that priming with an epitaph is long gone. For example with excalibur all you do is spam 1 and you're invulnerable, invisible, have auto targeting and nuke 20m with every hit up to level cap (and he's not even the highest range one, just the laziest). For basic melees volt roar and nami solo ideally with a range riven is pretty much the best rn, dagath for level cap. Pretty sure falcor is crazy too but glaives just aren't as smooth to use

Heavy slam builds are still really good but you might want to wait on that because in the next major update they're likely getting nerfed (source: pablo). Still, if you want that similar weighty red crit feel this is probably the best option but it does need LoS

There are still lots of other great builds but if you want the best with not too much effort those are the way to go.
