TE/HU might look something like this. Or at least, that's what I would do. I'm not a dedicated TE/HU main, so you might have to get a second opinion.
The endgame TE/HU Wand would be Zeinesis if you just want to get the Hero unlock out of the way, but if you're looking to seriously main it at some point, Zeinesis would actually not be the best option. The endgame Wand for TE/HU would be
Form Scythe. The only problem is that this Wand isn't readily available by any means and has to be farmed for manually, which is incredibly hard without getting some Nightmare Vegas Triggers from the Casino Coin Shop.
Just a heads up, but you may want to grind for a Zeinesis Talis on the side while you're raising up your Tech class, since if you're going to switch to Hero, you're gonna be using it later down the line.
