So you know, after you have played with NV companions, you just couldn't live to see your DC companions without their perks. I believe many people have the same opinion with me. There is no point in buying DC companions when you can get NV companions for free.
So here are my suggestions, I have given a lot thoughts about them, and decided to make DC companions (save for Fawkes) have the identical perks with NV companions. Just so modders can make it easily, and we can play it familiarly.
Dogmeat: Rex's perk, you can see the reason.
Charon: Raul's perk. He uses guns a lot and uses a lot of guns, and it gives him the knowledge to maintain equipment. Raul is a good repairman because he is a good shooter and he maintains his guns a lot. So it makes sense that Charon should do the same thing.
Jericho: Boone's perk. Sometimes he will tell you to watch out for snipers, plus the raider experience he had. Makes sense cause he had seen a lot, so he can always "spot" enemies before they see him.
Clover: Cass's perk. Might want to change it to work with all alcohol. She party a lot with Eulogy and should gain affinity with alcohol.
RL-3: ED-E's perk, again you can see the reason.
Butch: Arcade's perk. You two are bros in gang and that spirit helps you heal. Yes I totally made this one up.
Cross: Portable working and reloading bench. She is an android so she is able to do it.
Fawkes: There is no point giving him Lily's perk. But I can't come up with anything good and easy to make. So this one is left open for people's ideas.
Thanks for all who read these, especially ones that comment.
Even more thanks for someone who would make the mod, this forum exist because of you guys, so thank you very much.
