A sorcerer cannot use the known ritual casting spells in D&D 5e because a sorcerer is not magical enough to do so. Sorcerers are more along the lines of practitioners with little arcane talent. Given that it’s their profession, it’s safe to say they can learn any spell if they put in the time and effort into mastering it, but you shouldn’t just assume your Sorcerer can cast every spell just because he or she reaches level 10 like other classes might be able to do.
No. All the ritual casting spell are actually cantrips, so other class can cast them.
In D&D 5e it’s possible for some of your spells to be more useful than others depending on who else is playing with you.
However, since the player chooses what type of Sorcerer they want to play when they start that character (whether or not undead), and none of those options include an option for ritual casting–the answer is “no.” Sorcerers were originally designed as a rules light configuration in order to give players countless choices on how an arcane caster should be and act on the battlefield.
A sorcerer can learn and cast these spells, but they will not be able to change the spell level as other schools of magic might.
Sorcerers can indeed learn and cast ritual casting spells, but cannot prepare them. They are limited in their selection, so a sorcerer who is asked to undo vampirism may not know how since it’s not among their class options. This means that a sorcerer must find someone else with this ability before they can get rid of vampirism or go through the game-master for assistance. However, once a sorceress has learned the spell from some place she might have been able to use them for an alternate purpose (like sculpting) without changing her casting capability.
Wizards can take Ritual Casting as an Archfey patron option at level 2.
Sorcerers must be patrons of The Old One to use ritual casting spells.
The following are available to sorcerers who choose The Old One for their patron:
Acid Splash, Alter Self, Animal Friendship, Bonds of Fear or Chains of Fire (available only at 3rd level or higher), Fog Cloud, Speak with Animals and Water Walk.
Most rituals involve a 20-minute interaction that requires concentration and costs the caster a number of spell slots equal to the total cost of all material components needed for the ritual; to complete this process means committing two different spells from your list in exchange for benefits later on. These rituals produce the listed side effects when the spellcaster casts the spells that are being consumed for this process.
Drops one random item, which falls to the ground and smashes if it’s fragile.
Creates a spectral chime that reverberates with the spellcaster’s current thoughts for 10 minutes.
Yes. Even though the ritual spells modify normal casting and would not normally be possible for them to cast, since they are a class that knows some rituals, then they can use those spells in place of the regular spell slots to cast it.
For someone like a Sorcerer who has spells from different classes, any simple ritual casting with another class as long as they meet the level requirements will work – which is why anyone can become a “Fighter-cleric” or “Cleric-Rogue” type of character if they want! The limitations are all on what types of rituals each caster knows, so Clerics can’t do an arcane ritual for instance without already knowing Arcane Rituals in their lower levels to cast.
However, there is one exception I know of for this: Sorcerers who cast spells from the Warlock spell list. Even though they are Sorcerer spells, they are still Arcane in nature. As I recall, you can’t do this for Clerics because the rules state that Clerics can’t cast Arcane spells. Not sure about Warlocks though since it doesn’t say anywhere that they have to be Divine, just that their source is the Patron and they must be able to cast spells of specific levels.
If you can wait a day or two, I’ll try to get clarification on this one.
Anyway, hope that helps!
Yes, but the ritual only lasts a minute.
In-game this is represented by the Sorcerer, who can cast spells using their own mental energies without the use of a spell book or components for as long as they concentrate on this activity. Action and concentration stop Sorcerers from casting other sorcery spells while some have to keep concentrate in order to keep that effect going. This way of preforming magic is limited because it require at least one minute (round) of uninterrupted casting time and there’s a strict limit on how many rituals can be performed in “in an adventuring day”, with each different spell having differing time requirements and effects afterwards. Some sorcerers like Se’irim even need to take time out from combat between casts. The ‘no preparation’ rule for casting spells is still in effect, so Sorcerers cannot use ritual casting for this purpose.
