So Solasta was odd in that it diverted from the RAW 5e rules in that you could not change your spell slots without a long rest. In 5E you can do so outside of a long rest it just takes some time. This had the effect of making it so that you had to choose the identify spell slot in order to cast it as a ritual - so you are at least sacrificing a spell slot. Then the ritual takes 10 minutes per cast which they made happen in game time. That system works fine.
BG3 is in a different situation where ritual spells may not really work. Since you can switch spells at will but there is no time sacrifice for those changes. Then having a ritual spell would not have the same impact since spells slots can just be altered back and forth. On top of that there is no time mechanic where you can take x minutes to cast the ritual spell. You would just be creating a mechanic that may feel "out of place" or creates work for the sake of trying to make something fit. In essence you may as well make all ritual spells behave like cantrips (which they seem to do with Find Familiar) or you try to remove the need for the ritual spell (remove identify as a mechanic).
I am NOT saying either way is better. I am just pointing out that for BG3 ritual spells don't make a lot of sense.
Where did you see that you can change your prepared spells outside long rest in DnD ? I never read that.
The wizard can use ritual spells even if they are not prepared. Other classes that prepare spells have to do it first.
Anyway I really can't see your point
at all.
Why should we care that it takes no time ? Is the "10min later" screen in Solasta add something interresting ? Maybe you could add a suggestion to this thread to ask one ?
And even if we consider that the broken system to prepare spell is intended... Why would it be a problem to have (or not) to prepare the spell first ? This is a detail that doesn't add or remove anything meaningfull.
The only thing that could eventually makes ritual spell "useless" is to consider that the broken rest system is here to stay... But using spellslots over and over again and resting over and over again to cast spells that have the ritual tag in DnD is definitely boring in BG3.
What would be the problem to cast those spells "like cantrips outside combats" ? It may not be interresting but at least it solve something tedious and as much uninterresting.
There are tons of animals and dead you can talk with in BG3 and that's definitely very cool. But honnestly that's something I never get deep into because of the tedious spellslot/rest management needed to fully enjoy it.
Not sure only druids should have this quality of life (at least with animals) and that's exactly what rituals are for.
