Dead Ringer tactics:

1) kill first miniboss quickly. A good weapon or lots of damage boosts help, so make sure you collect some.
2) Whenever DR tries to run for a bell, tease him so he runs for you instead.
3) Meanwhile, destroy sarcophagi and their spawns.
4) Strike bells 1 by 1 and kill minibosses, while keeping DR from striking another one (see 2). Preferrably end with one of the bottom bells, with DR somewhere close to you (but not too close, so you still have time to dispose of the last miniboss).
5) When DR enters "angry mode", dodge him if you must, then go to the middle column and move up until he's right under you.
6) Sidestep. Win.

Just practice it with the bossmaster a few times, it's quite easy.

NecroDancer tactics:

1) Make sure you have at least 5 bombs (practically guaranteed after 5 zones) and don't have the blast helm on (otherwise you'll have to put extra effort into keeping Dorian safe while you are bombing).
2) Check the spare weapon which spawned for Dorian. If it's something you dislike, pick it up with Cadence and let Dorian have her weapon instead. She'll be using Golden Lute anyway.
3) Instead of fiddling around with the buttons, go straight to top right corner and bomb your way to the golden lute (3 bombs).
4) Pick up the lute, bomb 2 more "stage" tiles to release the NecroDancer.
5) Dance until he's dead. Try to keep Cadence & Dorian together horizontally at all times - it's crucial for your survival in case a red dragon spawns. And, of course, only approach the NecroDancer vertically, unless you are 100% sure you'll get to him before he bombs / freezes you.

That's what I do when I'm in the mood for deathless mode. Works like a charm, every single time, unless I do something stupid (like today)...

use a bomb or something on the top right bell, let dead ringer ring the top left bell, bait him into charging into and destroying another bell, then let him ring the last bell (one of the 2 on the bottom row), then just go up and down by where the gong will spawn and wait for dead ringer to charge you and kill himself
