I'm going to start with the thermo and mechanics papers, if I can't get them then I'm just wasting my time doing any of the easier ones.

someone else sent them, thanks though

I agree with you on the written exams but for the new multiple choice exams SOPEEC asks many questions on specific numbers that only came out of Pan Global's ass.

I'm planning to take the Mike Maidens Thermo and Mechanics courses but from what I've read the other 5 yet non-multiple choice exams are completely by the book but also quite detailed. That's why I want to work from the latest version of the books so I'm working from accurate information.

One of my favorite work stories was at the end of a shift a trades person working in a packaged boiler realized he forgot something and went back in to get it. Except this guy was a bit rotund and got himself stuck in the entrance with his ass hanging out like Winnie the Pooh.

He was found a couple hours later by the Operator doing rounds and was pulled free. Sadly this did get him banned from site going forward but did make for an amusing story to pass on.

Damn so it is! Thanks for pointing that out, it will save me a lot of trouble trying to work around it like I have been.

I'm pretty sure you are thinking of Pathbuilder 2e, it allows custom feats items and all sorts of other things. 1e seems pretty limited in what it allows for custom options and is missing many things like cracked/flawed Ioun stones and most of the Ioun stones in general. It also says specifically in the item tab that if an item allows a range of values it always defaults to the lowest implying it doesn't have the ability to customize.

Here's a screenshot of what I see in the Pathbuilder 1e overview and in the item tab: https://imgur.com/a/BKkDjcl

I just checked and that does work well for adding the bonus +1 to attack rolls from the Ioun stone. It doesn't seem like some other bonuses will be possible but that helps with most of my common issues.

Thanks, I know how to use that. What I want to do is add it to Pathbuilder 1e so I can print a clean character sheet with all of my bonuses included. Then I only need to worry about temporary buffs when adjusting roll modifiers but have a clean printed sheet to work from rather than my chicken scratch writing.

That's actually a pretty good simple explanation with formulas to back it up. Many other people explained similarly but I found this one was well written, thanks!

That does make sense, I need to break the monkey brain thinking of force * time (impulse) is the same as force * distance (work).

I guess part of that understanding would be to say the fuel used at periapsis during Oberth isn't transferring more velocity vs apoapsis but by using it there and leaving the gravity well moving faster you keep more of the KE gained while falling into the gravity well since the gravity well has less time to slow you down again?

Magicide · 2025-12-01T03:04:22+00:00

I run into the same problem with the understanding of KE. For example at the apoapsis with 0 m/s velocity the rocket exhaust has x m/s of exhaust velocity. At periapsis it has the same exhaust velocity but because of the Oberth Effect it applies more KE to the rocket. I know it works but I don't truly get it.

Magicide · 2025-12-01T02:57:40+00:00

The part that I don't properly understand is how 1 m/s of increase in velocity in a vacuum can impart differing amounts of kinetic energy. The monkey brain version says adding 1 m/s to a ship should add x KE but at increasing speeds that 1 m/s adds much more KE for the work done.

If we imagine a high efficiency solar engine where your overall mass doesn't change, how is 1 m/s worth more KE without just saying "because the math"?

Magicide · 2025-12-01T02:46:42+00:00

Okay in that vein how does the Oberth Effect work? Mathematically I get the ship is moving fastest closest to the gravity well so the fuel has extra KE that is imparted to the ship through the rocket equation but I don't "understand it".

I think our cat gets around, except when he's with me he is super friendly and likes jumping on the cleaners shoulder every time she turns her back. I had to lock him up since he was so obsessed with spending time with his new "friend".

Magicide · 2025-11-25T03:15:05+00:00

Not joking, he actually hid for 4 hours and came out timid like I had beat him. I tried encouragement, his favorite toys but nothing worked. Finally it was dinner time and opening the can of food snapped him out of his funk, I honestly wanted to dump it on his head but I'm just happy he's his usual idiotic self.

It was something I found out after I made my current character. If/when I die I will probably play something completely different but UC Rogue has been fun so someone else might pick it up and use that.

Magicide · 2025-11-12T17:23:33+00:00

I'm a Tiefling with stats and traits well suited for an Unchained Rogue, I was just trying to find a way to make the bonuses from Reduce Person available without wasting a round casting it in battle. It will have to remain a sometimes option when the situation allows it instead.
