Polymorph Any Object - New creature's health in cases where it didn't have health before

[CMantle]

So, Polymorph any object even gives the example of pebble to human, so we'll use a slight derivative of that. Let's say there's an enemy hiding behind a 5' x 10' wall that is 6" thick, made of stone. I polymorph that wall into, oh I don't know, let's hypothetically say I want to make a T-Rex or just anything in general big and scary to be hovering over the guy now. Walls, in the traditional sense, don't really have "hit dice" for me to apply to my new T-Rex, so does the "health" of the wall by its thickness become the hp of the T-Rex while it is in that form?

Do I convert the 15hp/inch for stone into the HP of my T-Rex? so a T Rex with 90HP? Or do I use the base stats for any T Rex's HP (which you wouldn't do if you were doing, say, a squirrel polymorphed into a T Rex)

Edit: I know the logistics behind this aren't great, since it would be a T Rex with base 10 physical stats, modified only by Beast Shape, so like a 14 STR. It's more just the idea of it for the giggles.

Paizo didn't publish any rules to cover the hit dice/hit points thing when changing an object to a creature. Guess they were in a hurry when they ported that. Expect significant table variation.

The whole realm of turning inanimate objects into living things isn't explored by anything official. My own thoughts is use the HP of the object as a guide line for the HD of the resulting creature, to a maximum of the actual creature's HP/HD. If there is more hp left in the object being transformed have some of the source left behind as a T-Rex shaped section becomes the creature.

If the player was going to use PAO as basically a longer duration animate objects spell I'd look at that for a guide line on stats for the T-Rex. To account for the transformation from animated object to an animal, instead of raising Str/Con just give them 10s for con/int/wis/cha. I wouldn't use the construction points, but look at a T-Rex for attacks, special abilities and so on. Creature type would be weird. Probably animal since it wasn't a construct before it was transformed.

And just to mention, this is a freshly born creature. It should know how to move, do attacks, and use all of its abilities. But it isn't on the caster's side. it just arrived with no memories or prejudices.

Honestly, it wasn't clear how that worked in 3E. Most of what I've seen of it went with the idea that you're actually creating a new t-rex with the wall as fuel instead of modifying the wall into a t-rex so just use the t-rex stats.

The spell has been maintained for retro compatibility with the 3.5 edition, but it works badly with the current rules. But it gives us an idea of how it work:

Quote:

If the target of the spell does not have physical ability scores (Strength, Dexterity, or Constitution), this spell grants a base score of 10 to each missing ability score. If the target of the spell does not have mental ability scores (Intelligence, Wisdom, or Charisma), this spell grants a score of 5 to such scores. Damage taken by the new form can result in the injury or death of the polymorphed creature. In general, damage occurs when the new form is changed through physical force. A nonmagical object cannot be made into a magic item with this spell. Magic items aren't affected by this spell.

No citation of HD.

I would rule that the HDs are based on those of the new form unless the effect mimics one of the other polymorph spells, so turning a wall into a T-rex will give you a T-rex that has 10 in its physical stats, 5 in its mental stats and 18 HD.

Transforming the wall into the same volume of acid will work way better (unless the caster is downhill ).

Now there's a simpler idea... Or lava.... or hot tar or grease bc it's flammable.... You've successfully annoyed my GM heavily for my next character... Transmutation Sorcerers are *fun*!

[CMantle]

So I guess the new question is *how much* lava I can make? Obvious you’re not limited by the size of whatever you polymorph, since you can go from a lizard to a manticore... so am I only limited by the 100cu ft per level? At level 20 could I make a pebble into 2,000 cf of lava?
