Harrow Systems is much easier to farm, and it has been for quite a while now.
I think it’s important to lead with that. For a long time, Harrow has been widely considered the worst frame to farm, with most of the player base opting and suggesting to simply buy him for plat. But as the Helminth system has been around for a few months now, I found myself with only 1 ability not yet subsumed: Condemn. I knew it was time to go farm Harrow.
I hear you moaning already: but defection is the worst!
Probably the hardest part of farming Harrow Systems is finding teammates to run it with you, since most people just simply refuse to play defection. It’s hard to blame them, since the best strategy involved a Slowva and a Trinity spamming their 4s while escorting a slow-moving pack of grineer lab rats. Even with hard-to-place wormhole shenanigans it was not a fun experience. What’s worse, you’ll almost assuredly never get a team to execute that strategy, so your actual experience is far worse.
But that strategy is very old. It’s 2020 and you don’t have to do that anymore. With this strategy, you can carry 3 random pubs/friends/clan mates with no idea what they’re doing, or just run solo:
All 3 of her motes buff the defectors. A standard max strength max duration build results in a shock effect that stops would-be attackers from attacking, a haste effect that sends them speeding through the map, and a heal effect that keeps them alive for the whole trip. Just go find where they’re coming from, drop the 3 motes in a choke point like a doorway, and once they run through it they’ll escort themselves wherever they need to go.
As for the actual farm:
You escort groups of grineer from their spawn points to an extraction point. Solo, you always escort one group at a time. In a squad, you start with one group at a time and quickly you’ll begin escorting 2 groups at a time. Squad play is significantly faster, and pretty much only requires 2 Wisps. You get a 2% chance at a drop on rotation B (6 squads rescued) and an 11% chance on rotation C (8 squads rescued). For this reason, it’s recommended to rescue squads in multiples of 8 (8, 16, 24, etc) in a group. In solo it doesn’t make too much of a difference if you stay past round 8 or reset.
TLDR: A standard big-numbers Wisp build makes defection absurdly easy. Tell your friends, and go get yourself a second Harrow to throw into your Helminth chair.
