So my intonations way off and everytime I fix it, it immediately goes back to exactly how it was. My assumption was the truss rod was off as it seems a bit curved, but im notsure. Ive tried to tighten it, but it doesnt really seem to do anything. The allen wrench always seems too small as if the nut isnt gripping it. Any suggestions?

Also, I know its EXTREMELY dangerous to mess with the truss rod, so Im being extremely careful.

EDIT: also, the fretboard seems to curve to one side( example: normal |, mine \), and I have NO idea how to fix that.

sounds like the neck is warping from what you say in your edit. If it's a new guitar I'd return it or send it back to the manufacturer.
How To Adjust The Truss Rod

1) Always make sure that you're in your desired perfect tuning pitch.
2) Measure your neck relief and see whether its proper. Fret the 1st fret low E and the 19th/20th fret where the neck meets the body and see the 8th fretwire. There should be a clearance of at least 0.3mm-0.5mm between the low E and the fretwire.
3) If the string lays dead on the fretboard/fretwires or below 0.3mm (0.2 i still ok IMO), then you'd need to loosen your truss rod. If the string is higher than 0.5mm, then you have to much neck relief, you need to tighten your truss rod.
4) Always tighten or loosen your truss rod in 1/4th of a turn or 1/8th of a turn each time, and let rest between each turn for about 10-20 minutes to let your neck adjust to its new settings.
5) Check your neck relief by performing step#2 again and see whether its proper. Also, make sure that you're still in your desired tuning and re-check every now and then if your tuning runs off.
6) After you've accomplish to let your neck relief to be at least in between 0.3mm and 0.5mm, again, let the neck rest.

- You can get extra hands and use a feeler gauge to measure your 8th fretwire or just simply capo the 1st fret. This is for more accurate measurement.
- Important* If your action is too high, that may also be the cause of your neck relief being higher than it should, i suggest that you restore the low E action to its factory setting (normally 2mm-3mm above the 12th fretwire) and measure your neck relief.

Thats what she said...
your allen wrench may be the wrong measurement- metric vs. american.

it's not EXTREMELY dangerous- make small adjustments and you won't ruin anything.
