ELEX II

I got a little ways into the game before doing this. easier the earlier you save up you ap and skill points.

what you do is, save all your ap and skill points (or as much as you can) from leveling up. stockpile them as best you can, you won't have enough until roughly lvl30.
AP (attribute) points are spent in intervals of 1 per level then 2 and finally 5 per level. which gets very costly.
you can find recipes and brew elex potions that give you 1AP each (10elex and 1wine each potion). and one that gives you 1 skill point (20elex and 1 moonshine), because I started stockpiling late I needed up brewing over 100 AP potions.
thats a lot of elex! to get elex somewhat fast, go to the alb base, tall to LOKEV the beggar a few times and he will tell you of a special permit in the scientist lab that lets you buy elex straight from KNOX.
the safe you need to hack is in the room all the way back to the left of the science building. for the code you need to pickpocket all the scientists for a piece of the code off each one. OR just enter

. once you have the permit you can buy as much elex as you want from Knox (25 a day).
also next to LOKEV is a BRAX after doing a mission for him he sells 8 elex a day.
for wine you can buy 30 a day from Chloe's bar in the berserker base.

you will need to have found trainers to use your skill points with. if you have found them you can press Y on the skill you want to learn to have marker on the trainers who can teach it to you.

SAVE BEFORE using your points after learning all the skills and you Get the achievement RELOAD your save before you allocated all your AP and skill points! and go for the next skill achievement!

in this case for the combat skills.
