An updated build would look like this then: better @TheAverageGortsby?
No, really, no, it's not. I have to tell you, honestly, it feels like you aren't taking the advice people are giving you so much as using this thread as a sounding board for your own ideas, and you're bouncing all over the place. And that's fine; don't think I'm suggesting that isn't fine. But you're just ignoring so many basic concepts that I honestly don't even know how to help.
Look. A week ago in this thread I suggested a build. I'm going to suggest it again, but then I'm done. Here's the build:
http://underrail.info.tm/build/?HgMDAwYDEAoAHgAAAAB4UF8AAEZQHjxGS8KgwqA8MgBBUCQrPxQqLmQ9IcKIwoffvwThat's it. That's the build. That's the best build. That's the best possible psi build for what you've said you want. You wanted sneaky? It's sneaky. You wanted to craft things? It can craft almost everything. You wanted grenades? You've got just enough throwing. You can persuade, you can buy the best stuff from merchants, you can hack all the computers, pick all the locks. You can hit every threshold in the game with a bare minimum of buffs. You can do
all the things. Assign the stat and skill points that are left over - you've got enough to put 50 in Intimidation (which will let you intimidate as well as persuade) and still have a few left over to shore up any weak points you think you see. Assign the feats that you want. But know that any changes you make to that build will only make it worse.*
You're overthinking this. Put together a character and play. You'll do just fine =)
*If you really wanted Grenadier & Quick Tinkering, or if you really wanted Interloper, you could pull INT down to 8, and get the stat (DEX or AGI) that you needed to pick up those feats. However, you'd then need to assign some extra points to the
seven skills you have which scale from INT. Still, if you think you're going to need it - which you won't - you can do it.
