Anyone else playing on very hard/hardcore? I've revised my character a bit after some more play through and analysis. Skill points are harder to come by with the lower bonus from INT, so I'm thinking a higher INT will be generally beneficial. I'm pretty sure you get 15 extra skill points per point in INT. It turns out the END mod counts against your mod total, so you need 7 base END to get 6 stats plus the 4 DT mod. This gives you an extremely strong character with high crit and lots of skill points to spend.
Final base stats after modding, without any gear on = 8 STR, 6 PER, 8 END, 1 CHR, 8 INT, 6 AGI, 9 LCK, +4 DT
As for skills, here's what I've taken so far. My character is capable of tearing up deathclaws on very hard with some relatively plain weapons just by procing crits all the time.
01 Fast Shot and Built to Destroy
02 Confirmed Bachelor
04 Rapid Reloads
06 Bloody Mess
08 Cowboy
10 Finesse
12 Shotgun Surgeon
14 Purifier
16 Better Criticals
18 Sniper
Working towards Ninja and Jury Rigging. Not sure on the last 3 slots but probably VATS related stuff.
Also, here's some hints to you aspiring thieves who want to grab everything not nailed down quickly without getting caught: First, crouch so you're [HIDDEN]. If you're [DETECTED] you'll get caught. If you're sure there is nobody around to catch you, you can grab stuff standing up. NPCs patrol around and move to different spots during the day and night, so if an area is crowded, try at a different time. If they're sleeping it's sometimes easier to remain hidden. You can sometimes push NPCs away from the theft target by walking into them, or talk to them so they face away from the target. If the item is not a container, you can press Z to grab it and drag it out of sight, then steal it. Moving items around doesn't count as theft. Close doors to block NPC line of sight, or push a barrel in the way between you and them. If all of that fails, you'll need a higher sneak level (try the Ranger Armor for +5 Sneak) or use a Stealth Boy.
