I can only seem to make about 1/1,000th C worth of delta V without exceeding 10 thousand tons of reaction mass or 1 year of burn time. So I'm what, 4,000 years away from the next nearest star?

Download the fusion pack in Steam Workshop. Do not go to star without fusion. ♫Current playing: "Fusion" from Kurzgesagt♪

What is the exhaust velocity on your MPD? Someone on this forum built a TW range MPD with enough eV to reach 1/100th C.

233 Km/s with hydrogen and 10 GW of power.

You might need moar power. Try my standard 10 TW neon MPD (1.06 Mm/s exhaust velocity), with 1 TW modded reactors. Or try fusion mods, but making that realistic takes a lot more effort.
(Though in reality, we're most likely to go interstellar using beamed power, like PROCSIMA

The easiest way to go interstellar is Orion, but CoADE can't model Orion drive properly.

The easiest way to go interstellar is solar sail, but it's going to take a while.

That's why I choose solar sail. Simple, you just need a reflective sail and a bit of computer and control.

A photon sail pushed by huge lasers should fare a bit better.

Even you push it with a huge laser, you still need to take a while.Unless your craft only weight a few grams.

Or just shoot your ship out of a cannon. It will reach the destination, eventually.

Shoot a Medusa ship whose sail doubles as a lasersail out of a mass driver aimed at a skyhook toward a low Solar pass → ???? → PROFIT
