I'm not sure why you would put some of the restrictions on this. Why not cast as a ritual?
Rituals complicate the way people rate spells. For example, some rate a spell as Not Bad in the sense that even tho it is substandard, at least it could be cast as a ritual if the unlikely corner case ever did come up. At the same time, others rate this same spell as Less Useful, in the sense that they would avoid choosing it for one of their precious prepared/known spells.
To avoid confusion, the standard assumes that there are no rituals, so all spell ratings can help a player decide which spells to prepare/know.
The no-ritual approach focuses on the spell description itself, how useful it actually is, and whether the spell was designed well.
Most of the spells are decent, but some outliers need attention. The thread by Yunru,
A Revised Spellbook, that seeks to standardize some of the inconsistencies, in part motivated me to do this thread.
I hope designers find this thread useful to design and adapt the 5e game, and DMs find it helpful when creating new spells, new archetypes for a class, or even new classes and races.
Why rate these spells as a Wizard if they aren't wizard spells?
There are various ways for one class to access spells outside the class spell list. Wizard traditions might grant new spells, not to mention Bard Magical Secrets, Cleric Domains, races, feats, multiclassing, prestige classes, magic items, and so on. So it is important to compare all spells with each other regardless of any class lists.
Note, gishy spellcasters like Bard, Druid, Cleric, and so on, tend to benefit from the spells that the Eldritch Knight benefits from.
Lastly, Prestidigitation is fantastic.
In other editions, Prestidigitation is a favorite spell. I consider it like a mini-Wish.
But the 5e version, what exactly it can do, is more carefully controlled. It can light your candles (if you have unlit candles prepared), wash your dishes, make your food taste good, chill the white wine, iron the table cloth, get violin music playing in the background, and jot down a list of items. Heh, it is basically a Restaurant Waiter cantrip.
(I cant even use the 5e Prestidigitation to wash my face and get a shave and haircut! − one of my favorite conveniences. And technically, I cant even light the fireplace in the room, since it isnt a ‘camp site’.)
The ability to produce a small item is handy (no pun intended). And the sensory effect is highly versatile.
Anyway, the 5e Prestidigitation is a solid spell, and fun, and versatile − especially for social encounters. But it isnt what it is in other editions.
For me, the 5e Minor Image cantrip is now my new favorite ‘Prestidigitation’ cantrip.
