So I pretty much finished a guns build at 26 and stuff.
90+ lockpicking
90+ science
90+ repair
100 guns
45 melee weapons
Medicine 75

So I have 9 levels, 144 skill points, 4 perks, to go till the cap and wondering if I could fit another build(ish) in there as either melee weapons, explosives or energy weapons?

Mix explosives and Energy weapons, become an hero god killing machine of the Mojave.

explosives its used more frequently with talking and quests but i do also like to use energy weapons just for sheer power

With the recent buff in some energy weapons was thinking of getting 100 in energy weapons, from 24. Also getting the meltdown and laser commander perks.

Get the Cowboy perk and acquire the .44 SWC schematics and turn that Trail Carbine into a real heavy hitter.

Maybe add a few points to Sneak

If i feel a build is kinda of finished early, I just chose perks that may not be the most useful but fit the character. Or choose ones that seems fun.

if you already got cowboy + a high gun skill you're probably doing more than enough damage.

I agree. The additional 5 levels would require me to do some serious self nerfing.

Already have cowboy perk.

@Demonhoopa, it's an additional 9 levels considering the DLC ;s
