Does Casting black tentacles on enemies break invisibility? I can see arguments both ways and I was hoping for some imput.


Personally.. yes and no.

Yes, if you intentionally place the spell over are area with opponents in it.

No, if you place it in an open space without opponents.


ah, good clarification there, thankee kindly Pathos.

I really think it falls pretty clearly into the "For purposes of this spell, an attack includes any spell targeting a foe or whose area or effect includes a foe." And thus it would normal break invisilibity.

Again if it is cast in an area that includes a foe -- if cast on the other side of an archway where no one is -- yet -- then it wouldn't break invisibility.

The sticker in this kind of case also, would be if there happened to be an invisible opponent in the area... *Pop* goes the invis, and the square where the invis opponent is would be revealed. :o)


Summoned creatures do not break invisibility, I would think that this would fall into the same category.

It would except for the face that the invisibility spell specifies than any spell with an area of effect will pop the invisibility if a foe is in the area of effect.

Since summons don't have an area of effect, and the magic of them doesn't directly attack they don't break it.

So how does that work then when you direct a summoned critter to attack a foe?


First the caster doesn't make an attack roll and the spell doesn't target a creature. Also it doesn't have an area of effect that can include a foe.

Basically it's on the same lines that directing a friend to attack a foe doesn't pop it or buffing your friend to hurt your enemies more.

The direct line from the caster to the target is broken.

Caster summons, summoned monster attacks.

As opposed to:

Caster casts spell that directly targets opponent, or caster casts spell that directly causes the target to make a save/ suffer an effect.

It is the same reason you can cast black tentacles in an empty space and have someone run into it, but not where an opponent is going to be directly and immediately affected.


However, regardless if you can communicate with a summoned monster or not, it responds to the caster's/caller's intent of attacking your enemies. That is their purpose.

The only way the summoned creature cannot attack is if you can communicate with the creature.

Again doesn't matter what the intent is. Obviously if I lay out a delayed blast fireball I'm intending to do some harm. But if it doesn't pop up the round I cast it then it becomes indirect (after all someone *could* pick it up and throw it back). Same with the black tentacles and a summoned monster.

It doesn't matter what the intent is -- again if I tell my friends to attack a certain guy it doesn't matter what I say I don't pop invisibility becuase it is an indirect effect.

Same with a summoned monster -- I cast a spell -- it brings me a friend. I tell the friend to attack (or the friend does just because it wants to help me).

I still did not directly harm my foe.

This sounds like a perfect opportunity for the FAQ button!


What happens if the area of BT has invisible foe in it? Do the BT's auto know where they are? Would you be able to see where the foe are in the T's?

The spell description says that the tentacles go after everybody, so I'd say invisibility is no defense. I'd also say that the person who is invisible is easier to find as tentacles bend toward them/around them.

"Bob, shoot the wizard!"
"Where is he? I can't see him, he's invisible!"
"Aim for the blank spot where the tentacles are bent down!"
"OK, got it. I think."

Maybe give the invisible character half their normal bonus on Stealth checks?

They just writhe about and latch onto whatever they can is how I understand it. The tentacles are not alive or they could be killed. It is really an AoE CMB.

This reminds me of an old 3.5 topic involving 'flaming sphere'. The FAQ said a wizard who was invisible could use flaming sphere on a target without becoming visible.

Not sure i see much difference with the tentacles spell.

You're misremembering it a bit.

Does casting flaming sphere in a non-offensive
manner—e.g., to start a campfire—count as an attack for
purposes of ending an invisibility spell?
No. As stated in the description of the invisibility spell,
actions directed at unattended objects do not break the spell.
You could use flaming sphere to burn down a whole village
and it wouldn’t end an invisibility spell, even if the ensuing
blaze included foes in its area (since that would fall into the
category of causing harm indirectly). (Of course, the Sage does
not condone such reckless activity.)

You'll note that the flaming sphere is

1. Not cast upon a target.
2. Not directed onto a target.
3. Causes harm only indirectly

Much like the fact that you can cast (evard's) black tentacles into an area without anyone and not cause the invisibility to end.

Now the interesting question is:
Should someone enter the area of the black tentacles (or the flaming sphere) would the caster become visible?

Likewise should a delayed damage spell (DB Fireball) cause invis to be lost after it goes off?

How about a cloudkill that then immediately moves into squares of people?

That is less cut and dry than the rest. As in each case it is the spell including people in its area of effect and affecting/dealing damage directly.

As a DM, I would rule that unless the spell caused damage at the time of casting, it won't break invis.

Cloudkill cast at the top of stairs and then rolls down into enemies? Won't break invis.

Delayed blast fireball cast at an empty square that goes off a couple rounds later? Won't break invis. (You're basically summoning a bomb. Summoning the bomb doesn't hurt anyone. The bomb exploding hurts people)

Summoned creature that is then directed to attack? Won't break invis.

That's my take anyway.

This would be my take as well.
