Ok so... heres my problem...

I'm lvl 39 have 95 AP points and want to use Action Boy and or Math Whiz to enable me to fire Christeens Sniper rifle 3 times in vats right...

I've got 3 perks left before current lvl cap...

So I look up the AP cost on the Fallout wiki and it says the weapon uses 38 AP per shot....

So np right... Math whiz makes it 34.2 a shot.... x 3 = 102.6

The problem is that when I go into vats as I am now with 95 AP each shot takes up half of my AP bar .... two shots leaves one AP nub... which cant be representational of 19 AP points could it ?

The AP bar would indicate the AP usage closer to 47-44 range

So I'm thinkin the wiki's gotta be off....

Any one know an accurate way to calculate AP usage?

I dont wanna Start investing in perks , get to lvl 45 only to find out it's not gonna work out.

Help anyone ?

I just checked the GECk and Christeen's POS Sniper in fact does use 38AP.

To check your actual AP usage, look in your pimpboy, check your APs. Fire one shot and immediately enter your pimpboy and see what you used. If you are on PC, and you don't know for sure what the actual AP costs for a weapon are, you can slowly add AP by console command until you get your three shots off. You will then know for sure. You can then become an honest person again by simply lowering your AP back to the original level.

I'll take her for a ride in my weapons testing facility with 95 AP and math wrath and action boy. Be right back.

Edit: OK, after two vats shots lined up with 95 AP, I had 7 bars of AP leftover. Giving myself only math wrath or action boy did not give me enough AP for 3 shots. Either both ranks of action boy or action boy AND math wrath was more than enough. Hope this helps.

Right on man thanks for testin this out for me but I just performed my own test using your suggestion on firing once and quickly checking my pip-boy to see how much AP i had remaining.... not good.... for some reason im using 44 a shot withe 51 ap remaining after 1 shot. ( with only 1 AP marker remaining as opposed to your 7 )

I'm on the 360.... could it be that they screwed this up for consoles?

I've tried looking over my perks and dont see anything that would cause greater AP usage... unless I'm overlooking somthing.



Anybody wanna help narrow this dissparity in AP usage down ?


Any 360 users wanna help check n see if we mighta got boned?


Thanks again for your help .46ACP

Check to see if you took trigger discipline as a trait. If you did, you gotta add 20% to the AP costs. That might be it right there.

Well that'd be it right there.... the trigger discipline description says 20% more slowly but are 20% more accurate.

I figgured I'd go from Bang,Bang,Bang!!! in realtime to bang....bang....bang

I didnt realize 20% more slowly equated to less AP

And I swiched the trait that gave +10 AP for Trigger Discipline in owb too.... lol



Hey thanks for the help again.
