20 Reflex+18 Tech IS A TRAP.
Instead of going for a 20 body/20 reflex/18 tech/10 cool/3 intel build, I dumped down from 20 to 18 reflexes, dragon strike is overrated and even in highest difficulty Don't Fear The Reaper you don't need the 25% extra crit damage, 2 attribute points for a bonus that's less than a single bully mod is overrated.
Tech also is wasted attribute points, you don't need Satori legendary at all.
I went 20 body for the knockdown immunity, which is invaluable against exoskeleton cyberpsychos who stunlock you to death in melee without it.
I then dropped Tech down to 14, and used those 6 points to pump Cool to 16.
16 cool is huge. You get Cataresist for 35% resistances, Inductor for 50% extra armor instead when you are shocked/EMP, gives you a 4th stack of Cold Blood, Cold Blood trigger on critical hits, Cool Blood maxed and refreshed instantly when you hit 45% HP, 5% resistances per stack of cold blood.
At 16 cool, with an extra 6% resistance and extra 12% extra crit damage with cold blood up just from the attribute (so you are merely missing 13% crit damage from dragon strike, 2 % chance to crit, and 6 mantis blade damage)
Cold Blood at 16 cool gives you:
-50% extra headshot damage
-80% more armor
-20% extra resistances
-120% more attack speed
-40% increased weapon damage
- You only lose stacks 1 at a time between periods of non-combat, and it's very easy to max them
You exchange 40% armor from tech for these, but it's actually 20% armor loss only because 16 cool gives you one extra stack of cold blood, so 20% armor x4 vs. 20% x3, in exchange for 6% more resist+ access to legendary cataresist for 35% resistances vs. 12% from 8 cool green (23% extra resistances).
16 cool also allows you to pick up Inductor for 50% extra armor when shocked/EMP, on top of instead of being vulnerable to burn, you do 10% more damage while burn debuff is on you.
More importantly, Tech perk levels are garbage, they only affect crafting costs.
Going from 10 cool to 16 Cool nets you 5% more resistances, 10% extra chance to crit, 5% extra crit damage, and 3% movement speed. You lose 3% dps from 19 reflex perk.
Yes, you crafting Legendary Satori and armor will yield higher baseline armor (much less mitigation, however, than Cold Blood at 16 cool when it's up), and Satori is plain broken damage.
But you'll be much more glass cannon with 18 tech and 20 reflex with honestly redundant extra damage.
Meanwhile using my Legendary Mantis Blades with 16 cool on Don't Fear The Reaper, I grab the enemies with the normally annoying mantis blade animations that would in other situations get you melted, and I TAKE NO DAMAGE BECAUSE WITH COLD BLOOD I AM LITERALLY IMMUNE TO DAMAGE. I'd have to run into multiple explosions or tank like 3-4 machine gun goliaths in Don't Fear The Reaper to be in any dange, and not once was my biomonitor or second heart popped.
I was still 1 shotting regular mooks with heavy mantis blade attacks and 2 shotting the machine gun Goliaths. Killed Adam Smasher in 12 seconds without taking any damage.
The one noticeable loss from dumping Tech is that Mechatronic Core cyberware legendary which gives 50% extra damage to mech/drones/androids drops down to green version of 20% extra damage, so you lose 25% extra damage to mechs, but it doesn't really matter because I am still 2 shotting the mechs in Don't Fear The Reaper on Very Hard.
The main attraction of Tech was supposed to be able to not look like a clown since you'd be able to craft your own armor, but the legendary armor specs are super limited, most of them ugly as sin, the only extra helm you get is an awful beanie or a decent cowboy hat.
I suppose you can go Tech if you plan a gun based build since being able to craft legendary guns is pretty nice. But if you play melee and enjoy Mantis Blades or Gorilla Arms or Monowire, Cool is such a vastly better investment.
Crafting in this game is very tedious too, single craft components you have to mod in PC to be able to multicraft, since leveling crafting takes long, by the time you want to craft legendary stuff, the mats cost, especially epic and legendary armor is crazy high, so you either dump money.
In any future runs that don't involve gun play, such as net runner or melee, I am going 16 cool instead of 18 Tech.
