I love the IED ships conceptually, they absolutely fits into everything we know about the luddic path, and past atrocities committed by them.
But the implementation of their allahu akbar mechanic kinda sucks (shieldpiercing dmg that even blows up ships in phase space), so I went and got some help from the modding community on the inofficial discord. I heard there is a mod-update in the woodworks that will separate these 3 ships into their own little optional submod, but for those who don't want to wait, or want to preserve their current save, you can do the following:
1) locate the file "default_ship_roles.json" in "[Your Installation folder of Starsector]\mods\Luddic_Enhancement\data\world\factions"
2) Open it with Notepad ++ or any other Editor you feel comfortable to use.
3) Add "#" in front of the following lines: 23, 46, 69, 130, 133.
- Optionally, if your editor does not number lines for you, press strg+f to bring up your editor's search function, and search for 2x "dram_lp_ied_std", 2x "phaeton_lp_ied_std", and "prometheus_lp_ied_std". You have to search for dram and phaeton 2 times, because they have 2 separate entries in that file. Add a "#" in front of their lines.
4) Save the file, and restart the game.
To revert these changes, simply delete the "#" from where you've added them.
If you only want to get rid of the prometheus, but keep phaeton and dram IED's active, you can do that by not adding a "#" in front of their lines.
You will still have IED's in your active save, but the luddic path is now no longer spawning new ones, and capitals / tankers in their fleets will spawn with other hulls instead. After 2 or 3 ingame months, all IED's should have despawned or been taken out.
I hope it helps :)
