Enlarge/Reduce

I just caught theres no size limit to the object you're casting this on *looks at planet he's standing on*

I can see some shenanigans for reducing a house or cage people are inside of... or a boat people are on. But probably more in line with what a dm would allow, this is great to get past locked doors assuming you never need the door again. Reduce door, door falls out of frame, walk thru. 

How does this pair with animate objects? Like if you reduce an object a size then animate it, then drop concentration on reduce, does the animate stats change?

If one were to play, oh I don't know...a grung, theoretically could I have another player cast this on an enemy, and on a high enough roll, just eat said enemy? Or would they return to normal size?

There's nothing in this spell that says it ends if the target is eaten by something.

Unfortunately, the definition of "object" in the Rules Glossary does make it clear that something like a house, or a boat, or a planet is not an "object" in the sense in which the word is used in D&D rules.

I would say that an object animated by Animate Objects always uses the stats associated with its current size, and so if its size were changed after it were animated, the stats would change accordingly. However, since both spells require Concentration, you'd need a second caster to actually make any use of this.

I also happen to have a question. What happens if you cast Enlarge on a Gargantuan creature, or reduce on a Tiny creature?

Its size category doesn't change (because there aren't any size categories smaller than Tiny, or larger than Gargantuan) but the other effects would still apply.

 is colossal no longer a thing?

There has never been a size category called "colossal" in either 5e or 5.5e D&D. Perhaps there was in some earlier edition, I'm not sure.

It was in 5e but it just meant anything larger than gargantuan, It was also in 3.5e

There's no mention of it in the 5e Player's Handbook rules on Creature Size; Gargantuan is specifically defined as "20 by 20 ft. or larger", making it the largest size category.

I recently had a player that wanted to cast it on a lock door to open it. Felt wrong to me but couldn't find a real explanation. 

can that spell  be use in that way ? Or on the lock or something else to open a lock door ?

With the lack of specifics on size and weight, and only listing a change in category, would I be mistaken in believing this leaves room for players and DM to discuss and decide how much growth/reduction actually happens?

For example going from medium to large. Rather than just doubling height (and increasing weight 8×) you could choose in the casting how much they grow within the limits of size large (8 to 16 feet tall) and increase weight accordingly, via the square cube law?

I would actually say that since the spell doesn't say the target's weight changes, the target's weight doesn't change, but it's certainly a gray area that individual DMs could rule on.

I don't see any reason you couldn't use this spell to reduce the size of a locked door to get past it.

This is a 2nd-level spell, and there is already a 2nd-level spell that unlocks doors (Knock) so it doesn't seem like this usage would be overpowered or anything.

Do we think this stacks with Barbarian’s primal knowledge?

 Technically, you have to see what you're casting it on. How you define the lock is a little muddy at that point, whether the locking mechanism and key hole count as the same object or not.

Getting thru a door should be fairly easy though. You could shrink the door itself with this.

That doesn't make this any less powerful though for those shenanigans. Enlarging or reducing a portion of a boat's hull would rip a giant hole in the boat, and the boat sinks. Shrinking a support beam or wall of a building will collapse the building. I suppose you couldn't destroy a planet tho...

How does the enlarge function affect grappling?  Under the new grappling rules, the target rolls Athletics or Acrobatics vs a DC based on the attacker's STR and Proficiency.  Does the advantage on STR checks from enlarge add 5 to the DC (based on how advantage works on passive numbers)?

They don't exactly "stack" because they do different things, but if you're asking whether the advantage/disadvantage on Strength checks provided by this spell applies to Strength checks you can make with normally non-Strength skills via Primal Knowledge, the answer is definitely yes.

No. The spell doesn't say it does that, so the spell doesn't do that. Having advantage on ability checks with a specific ability has no impact on save DCs calculated using that ability's modifier.

That said, that seems like a very reasonable house rule.

Sphere of Annihilation that’s all I’m going to say.
