Can a multiclass sorcerer/cleric use the Metamagic class ability with non-sorcerer spells? For example, using Twinned Spell when casting cure wounds to heal two creatures instead of just one?
[RPG] Does a sorcerer’s metamagic work for non-sorcerer spells
Yes, Simulacrum can be twinned
It creates one duplicate each of two creatures.
Just to take the first line of the Simulacrum spell:
You shape an illusory duplicate of one beast or humanoid that is within range for the entire casting time of the spell.
The target is one beast or humanoid within range touch.
There's nothing logically stopping this from working. Simulacrum doesn't target self or more than one creature.
And to pull out a line of the Twinned Spell feature:
[snip] ... target a second creature in range ... [snip]
If you had two people (one of which could be yourself) within the range of "touch" for 12 hours and you have the sorcery points (you'll need seven), then you should be able to twin the spell and create two duplicates: one of each creature.
Also as a restriction of Twinned Spell, a twinned simulacrum can not be used to create two duplicates of the same creature.
So, to answer your questions succinctly:
- No, a twinned simulacrum must target different creatures.
Spiritual Weapon (Hammer) can not be twin cast
It doesn't target a creature at all, so it is not twinnable.
Dominate Beast is eligible, and presents a sticky situation
As you've quoted, the language of dominate beast states:
You can use your action to take total and precise control of the target.
Spell is twinned for two targets, but the spell language doesn't change
Once twinned, you now have two beasts under your control, but unless you have a means for a second action, you only have one action available to control one beast. The twinning of the spell only allows you to target two creatures, it does not change the wording of the spell used.
This means you are still limited to controlling one beast with your action.
The argument for allowing it
The other side of this is that with Twin, you aren't casting two spells, but just one spell that has two targets. Anything you do afterwards would be twinned as well and thus a single action would be sent to both beasts.
Unfortunately, this does seem like it can be a DM decision and what feels right at your table. There is reasonable logic for each case.
Sorcery points are not restricted in which spells they can affect.
Other class features similarly work between classes, as the classes merely grant abilities and few of them state that they have any form of exclusivity. Metamagic abilities and other methods of spending Sorcery Points are not restricted to only affecting Sorcerer spells.
Considering that in addition, Spell Slots are universal, it doesn't appear to be game-breaking since multi-classing also limits the ability to get more sorcery points.
