Channel Vigor While Paralyzed

I cast channel vigor on my character the round before he was paralyzed with a spell, Hold Person. Can I use my move action to change it from Torso to Mind?

I dont know if the hold person text, which specifically says you can do no actions, only mental, would mean you cannot use the move action to change from Torso to Mind. Is the changing of the ‘focus’ actually requiring movement?

How does Channel Smite work?

At level 4, Berric the cleric takes Channel Smite. He then attacks someone, expending a Harm spell. From the text:

Make a melee Strike and add the spell’s damage to the Strike’s damage.

Does this mean that the basic Fortitude save mentioned in the text for Harm simply isn’t used? If Berric used a first level spell slot, which of the two possibilities below is the case when he strikes and hits?

  1. He strikes, dealing his normal weapon damage and then simply adding another 1d8.
  2. He strikes, dealing his normal weapon damage. The enemy takes 1d8 damage, but rolls a basic Fortitude save: it takes none of that 1d8 damage on a critical success, half damage on a success, full damage on a failure and double damage on a critical failure.

I think it’s the first, because the text for Channel Smite doesn’t mention any saving throw, but I’d just like to confirm…

Does Harness Divine Power use Channel Divinity?

The Harness Divine Power optional feature from both the Paladin and Cleric class in Tasha’s Cauldron of Everything says the following:

You can expend a use of your Channel Divinity to fuel your spells.

It then goes on to say that you can touch your holy symbol as a bonus action to regain a spell slot, which you can do once per day, or more at higher levels, neglecting to say anything about using Channel Divinity. Does it require Channel Divinity, or not?

Where can I find the other Channel Divinity options for Clerics that are hinted at in the PHB?

For a Cleric, the PHB shows two Channel Divinity powers: Turn Undead and Divine Fortune.

However, it says there are other Channel Divinity powers, but I can’t find out what these are.

What are those other options and where can I find them? Are these (and the previously mentioned ones) available to a first level character?

Can channel divinity affect a fiend in the ethereal plane?

In a fight with a Night Hag coven one hag uses the Heartstone to become ethereal, I know that divine sense can’t reach into the ethereal plane and sense her. But can a Channel Divinity affect her?

For example, the Oath of the Ancients paladin has this Channel Divinity option:

Turn the Faithless. You can use your Channel Divinity to utter ancient words that are painful for fey and fiends to hear. As an action, you present your holy symbol, and each fey or fiend within 30 feet of you that can hear you must make a Wisdom saving throw. On a failed save, the creature is turned for 1 minute or until it takes damage.

A turned creature must spend its turns trying to move as far away from you as it can, and it can’t willingly move to a space within 30 feet of you. It also can’t take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there’s nowhere to move, the creature can use the Dodge action.

If the creature’s true form is concealed by an illusion, shapeshifting, or other effect, that form is revealed while it is turned.

Will it make the hag turned?

Can Dispel Magic stop a Channel Divinity?

The spell Dispel Magic reads:

Choose one creature, object, or magical effect within range. Any spell of 3rd level or lower on the target ends. For each spell of 4th level or higher on the target, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a successful check, the spell ends.

The Cleric’s Channel Divinity feature reads:

At 2nd level, you gain the ability to channel divine energy directly from your deity, using that energy to fuel magical effects.

Am I correct in my understanding that Dispel Magic would have no effect when targeting a magical effect caused by Channel Divinity because Channel Divinity is not a spell?

Do the War Domain cleric’s Channel Divinity options Guided Strike and War God’s Blessing stack?

The War Domain cleric has the Channel Divinity option Guided Strike (PHB, p. 63):

Starting at 2nd level, you can use your Channel Divinity to strike with supernatural accuracy. When you make an attack roll, you can use your Channel Divinity to gain a +10 bonus to the roll. You make this choice after you see the roll, but before the DM says whether the attack hits or misses.

The Channel Divinity option War God’s Blessing allows an identical benefit to extend to another creatures:

At 6th level, when a creature within 30 feet of you makes an attack roll, you can use your reaction to grant that creature a +10 bonus to the roll, using your Channel Divinity. You make this choice after you see the roll, but before the DM says whether the attack hits or misses.

If two War Domain clerics were in the same party, and one uses Guided Strike to add +10 to their attack roll, could the other War Domain cleric use War God’s Blessing to add a further +10 to that attack roll?

Or would they not stack, as they are the same source (i.e. a War Domain cleric’s Channel Divinity)?
