I'm hashing out a collective of NPC Rock Gnomes who live in a small stone castle shaped like a Huge person, about 15 x 15 x 22 feet, which is the maximum size for a creature of Huge size. This collective of gnomes will have two basic talents that they excel at one of which will be:

  • They can animate their castle and enlarge it both to travel short distances and as a defensive measure against creatures of ill intent.

Animate Object states (PHB 213):

You can’t animate any object larger than Huge.

Enlarge/Reduce states (PHB 237):

The target’s size doubles in all dimensions, and its weight is multiplied by eight. This growth increases its size by one category—from Medium to Large, for example.

My question is this: If the castle is currently a Huge object and it is animated as a huge object and then it is enlarged and becomes a Gargantuan object, does the Animate Object spell continue to function?

I know I can bend the rules for NPCs and I'm o.k. doing that if I need to, but I'd like to know RAW on this.

The gargantuan animated object continues to be animated.

In this tweet Crawford claims that:

No longer being a valid target trumps condition carryover.

So whether a gargantuan animated object continues to be animated, hinges on what a valid target is for the animate objects spell. The relevant limitation is this:

You can't animate any object larger than Huge.

However, the animate objects spell also says that:

Each target animates and becomes a creature under your control until the spell ends or until reduced to 0 hit points.

Moreover, as Slagmoth explains in this answer:

Nothing is considered an object and a creature simultaneously.

Therefore, enlarging a huge animated object doesn't make it an invalid target of the animate objects spell, because you enlarged a creature, not an object.

In other words, to make the target of the animate objects spell invalid, you must enlarge the object. However, that's impossible to do for the duration of the animate objects spell because there is no object for you to enlarge.

  • \$\begingroup\$ This hinges on whether you interpret "animate" as a one time action or a continuous one. If you "animate" the object when you cast the spell and then you stop (it is just animated), then that condition of the spell will no longer bind you. But it can be read that you continuously "animate" the target, in which case the restriction stays for the duration of the spell. \$\endgroup\$

  • \$\begingroup\$ @Szega my argument hinges on the facts that the animated object is a creature, and that restrictions on objects do not apply to creatures. Whether the animation is continuous is irrelevant to my argument. \$\endgroup\$

  • \$\begingroup\$ As you also state, in regards to the spell the target is still an animated object, otherwise it would be an invalid target and end the spell. Thus the restriction can stay in effect. \$\endgroup\$

  • \$\begingroup\$ BTW, I just found this: Does a spell persist if it is cast on an object, and the object changes into a creature? \$\endgroup\$

It deanimates

In this tweet, 5e rules designer Jeremy Crawford gives his unofficial ruling:

No longer being a valid target trumps condition carryover.

The subject has changed in a way that makes it an invalid target for animate object and thus that spell ends on it.

    \$\begingroup\$ Is it worth clarifying that usually spells with a duration of 'instantaneous' would carry over, but anything such as this with a longer duration (Such as 1 minute for animate object) indicates continual magic which is why it can become invalid after the initial cast? \$\endgroup\$

    \$\begingroup\$ @SeriousBri Could you point out a specific case where this would be of concern? Obviously you do not reverse all damage you have received if you are turned into an object and thus couldn't be targeted by the spells that hurt you. \$\endgroup\$

  • \$\begingroup\$ Not off the top of my head actually, if it doesn't sound obvious to you then maybe it isn't as much of an issue as I thought. \$\endgroup\$

  • \$\begingroup\$ I de-accepted your answer only because I rushed into doing that initially and I probably should have been more patient. I still like what you wrote, but, especially considering someone has posted a counterpoint, I want to take time to consider which answer makes the most sense. And also wait to see if any other opinions present themselves. I hope that sounds fair to you. Thanks. \$\endgroup\$
