Fallout 4 Tips to Level Up Faster

Call for Help

If you stumble into a tough fight and you don't want to lose, don't be afraid to call in some backup/help to even up the odds.

When you join a faction and you advance through a few quests, you'll be given a calling card that can be used to call in backup.

For instance, the Minutemen will give you a Flare Gun to call in fire support. You'll also find smoke grenades to plot out targets for artillery strikes.

If you advance far enough into the Brotherhood of Steel you'll get a handy vertibird signal grenade. It can take you around the map and/or you can use its mounted gun to wipe out enemies. 

Make sure you're stocked up on these when you roll out. There's no telling when they might come in handy for you.
