Maxing Alpha in current version?

If I go for Alpha, what are the min stats that I need to get the most out of the Prime mutations? I doubt I’ll have enough points to get all 4 stats to that base level, so I’ll reduce one stat and at least try to get 3 to the Alpha max and the other to the next lower level. I’m thinking of going 15, 15, 15, 8 to max 3 stats and get 15 for the fourth. Is that still correct?

You are correct. Stat 1-6 gets you a 8. Stat 7 gets you 11. Stat 8-14 gets you 15. And finally stat 15 gets you 18.

You might also consider getting the lesser boosts if you’re okay with sacrificing perception a bit further. With Elf and Troglobyte mutations (Or pre-threshold Alpha I think) you would come out 19, 19, 19, 12 instead of the 18, 18, 18, 15 that alpha would give you. Perception doesn’t really do much over 12 unless you’re using them kitaners alot.
