Re: Amazon Tech level as a populace I thought that they were not terribly magic-oriented.
Well, yes, as per Perez, that's true, but the gist of my comment above is that that feels like a misstep to me. Having made Diana so much a creature of myth and magic, it seems very unfinished to leave her culture behind - particularly considering how much that culture is designed as an extension of her and she of it, as I'll get into a bit next chapter.
Divinely-oriented, yes, but I think magic is a bit of a different creature.
Fine for D&D, but in the DCU, that's a bit of a false dichotomy. Magic can be more or less regimented, more or less organic, more or less powerful, but in the end it's all the same sphere. The Spear of Destiny is a magic artifact, guarded and disputed by magic beings, which can be used to slay a creature of magic. Said creature of magic is the agent of the divinity in the DCU (the Presence seems to trump all embodiment-type deities). Zauriel, an angel, was chosen for the League and to steward the Helmet of Fate due to his familiarity with magic, and he and Blue Devil, as members of Shadowpact, were both familiar with the rules-and-spells world. (Similarly, Ragman is an agent of God and is very much about powers and bargains). To get topical again, Diana's lasso is considered magic, called magic, treated as magic, complained about as magic, is basically unquestionably magical... but the thing it's actually doing is channeling her divine nature. Diana's magic because she's a demigod (and was once a straight-up god, no prefix). There's no real line between divinity and the arcane in that sense, in the DCU. It's more like... Diana is to Zatanna as Clark is to Steel. Both women use magic to kick ass, both men use science; Clark and Diana have an organic, built-in powerset, Zatanna and Steel use the rules and formulas of their chosen medium to produce a wide variety of different mechanical results.
The amazons, though, despite being connected so closely to the magical through Diana and through their own creation as divinely (read: magically) superior beings, have never really had much of either category, when you'd expect them to have more of both. If you look around Perez' island... where are the hippogryph chariots, the phoenix aviaries, the more organic, or, we'll say, divine kind of magic? And if they're immortal and surrounded by this magical Veil that keeps the world out and this pit to another dimension, where are the magelorists who study those phenomena and start laying down the rules for magic that will inevitably lead to practical utility of same (arcane magic) the way scientists inevitably find practical utility for the science they develop? It just seems... a bit unfinished.
