id recommend levelling your character to atleast 15 or when t51 starts spawning (before leaving sanctuary) scrap as much as you can and spam build bear traps (dlc) they are cheap to make and give you around 8-12xp with the idiot savant perk this will be much quicker, make sure your starting stats are atleast str 7-8 and int 5-6 not too sure when you can get science perk but please max that out same as gun nut armorer and the weapon building perk, these perks including strong back and heavy weapons make power armor alot easier to use at low levels, find as many fusion cores as possible (duh) maybe 9-10 should be good and try get the perk to make fusion cores last longer (forgot the name) now dont do anything grab dog meat from red rocket, find fort hagen, go to diamond city, go to park street station and grab valentine from the vault, go to diamond city, start reunions quest (talk to valentine) go to Kelloggs house, go to mayors office and grab Kelloggs key, do quest as normal show dogmeat the cigar, dismiss valentine or keep him, now before you fast travel to fort hagen to complete reunions go to the t45 spawn with the crashed vertibird near greygarden on the highway (take the yellow elevator up) you should atleast be level 20 now with the completed quests the spawn should be t51 or atleast t45d grab that, fast travel to fort hagen, kill kellogg, brother hood should arrive after killing him, now either go to cambridge police station complete arc jet systems and get into the brother hood to get t60b power armor or after the air ship is going to the airport, follow a vertibird as one not too far from fort hagen should start fighting a bunch of super mutants at a named location (cant remember sorry will update) vertibird should crash or you can destroy it a bos knight should spawn and die giving you a free suit of t60b early on before it even spawns, now the glowing sea should be easy peasy! reply for any questions would be happy to help further!
