What the hell are you on about? You're speaking English, but your words make no sense. Evocations are cool
This is a subjective opinion. You think so, okay, whoopee for you. But not everyone feels the same way. Some people - myself included - are bored to tears by the relentless pushing of "YOUR LEGEND AND HEROISM MUST BE BASED ON A SPESHUL SNOWFLAKE WEAPON OF SPESHULNESS AND LOOK YOU CAN BUY LOTS OF CHARMS FOR IT WHEEEE", and would actually rather not have all their power tied up in something that can be lost, stolen or broken in half. And however much you say this, it does not change the fact that the setting is described as having
thousands of Artifacts, if not tens of thousands. Again, look at the Realm. Are you seriously trying to tell me that when there are ten thousand "unique items with powers based on their histories and power", they still all feel just as special and unique?
Because here's the thing about Excalibur and Kusanagi and so on.
They're fucking rare.
They're
genuinely unique; there are only a handful, if any, artefacts in their home settings that even come close to them. Your example of Servants in the Nasuverse (urgh); there are seven of them and
that's it. There aren't
thousands to tens of thousands of the bloody things.
Evocations seem very much like they're just going to be the Martial Arts Styles of 3e. Big long bloated disconnected Charm Trees that suck up a bunch of the dev's attention because they're the "pets" of one of the editors, where homebrewed ones are almost always either terribly mechanically written (cough
Cobra Style cough) or badly fluffed, or both, and which are relentlessly pushed in your face repeatedly and
endlessly, even if you have no fucking interest in them whatsoever. Oh, and either each one is going to need three to eight different Charm trees for different types of Exalt, or the setting is going to snap like a twig when a Dragonblood gets their hands on an Artifact built for a Solar and starts using Evocations balanced against Native Solar Charms.
The system really needs a third tier between 'equipment' and 'relic'
Hence, "lesser artifacts".
Don't need a charm, let alone a homebrewed one. Just reach Essence 4, and start boinking to make yourself some Half-Caste offspring. Alternately, if you want something faster, use the mirror of the Solar Lore charm that gives people Awakened Essence and Solar charms, for a rather hefty committed mote cost.
The only people who should be able to use Solar Charms - especially given that Taboo-Inflicting Diatribe is Essence fucking
2, and can be used to mindscrew a kingdom into handing itself over with little to no effort - are Solars. If Enlightened mortals learn Charms, it should be Spirit Charms or nothing. (Or TMAs, if you feel you have to torture yourself by using the martial arts system as it currently stands in 2e.)
