also I'd just add a bottom strap to keep it in place and use velcro to attach because I struggle with zippers as someone whos sewn for years, I would not recommend them for a first project lol, velcros easy you just cut to size and sew a box around it

I would definitely suggest watching some tutorials on machine basics before attempting it because there are some funny inverted corners in it, anything that explains how to sew a cube should be pretty helpful

once you have those numbers, its easy to just take each flat plane, add a 1/2 to a 1/4 inch seam allowance (bigger is easier for you as a beginner) and cut each piece out

then you just need to assemble it like a puzzle piece one bit at a time

first thing you'll need to do is take all the measurements you're gonna need
-the pad itself
-how tall you want the "walls"
-how thick for the "walls"
-any angles or cut outs you'll need to accommodate the machine itself like the hand rail

this is absolutely not impossible, but may be a little complex if you've not got a lot of sewing experience

personally I'd use upholstrey foam to create the cushion shape itself because it'll be much easier to make the shapes you need here, then sew a cover separately that can be washed

I love him so much but 2 barrier mages might be your best bet, thankfully I definitely found Tresspasser more forgiving in that you can kinda bring who you want

oof its has been, a while, since I last played it unfortunately, but from a little digging, the final boss is lightning weak, not certain if all of the rock bosses are however, I did find it a lot easier with a very high defense tank with sword and shield, and at least one barrier mage also
