I went with like 5 points on charisma and 3 points on everything else except agility is it good or should I just focus on some stats only ?
And it also says there will be tests so I'm wondering how many stat points do I need for them ?
I just act as a generalist, then level up like crazy to get the stat points I need. Simply I take the stats I need to complete a part of the game and then after that go on a rampage fighting everything for my other stats, usually at the start I put int at 8 and everything else at 5 or 6 and then after I start I focus on getting strength until it's 12, after I just add to what I feel like. Somehow my character isn't a mess and can do most things after a grueling power leveling I recommend fighting the ratkin at the beginning of the game since they give a lot of exp and are relatively easy to deal with since you get extra tease with them, another thing that helps is equipment since it gives you some boons to stats, health and libido.
So yes it's good to go generalist but you need a lot of power leveling and some equipment to make up for what you lack, also potions help a lot since there are some to boost stats temporarily.
