Sorry, I missed that. I would think there would be more acid available than alchemists fire, but that it might not be stockpiled as effectively. The joke still applies.As I said above, it should be acid. And the city itself would have huge stockpiles of them (less for acid than for alchemist fire, but there are industrial applications for it).
Now who is going away from what the rule book states? (Not that there is anything wrong with that within reason). The stat block only lists bludgeoning damage from weapons. Not bludgeoning damage in general. Specific beats general in the rules.There is no difference between bludgeoning damage from falling or from weapons. Unless falling damage is its own damage type immunity would protect from it.
I don't find myself beholden to an artist's rendering. The Tarrasque in my mind is closer to Godzilla or a Gargantuan, deformed T-Rex. But looking at the artwork, the Tarrasque is not a quadruped. In the three pieces of artwork we are given, it never walks on 4 limbs, even when it is bent over. Even though it doesn't have the flexibility of a humanoid, it looks like it could at least throw straight outward. With its size and strength and height (the top picture), a long throw still applies. The top picture also shows the fingers curling around.But that doesn't matter as the Tarrasque would be unlikely to throw anything anyway. First it is not in the rules and second it is very unlikely that the claws can grasp a creature or that the arms anatomy would allow it to throw something very far or with good accuracy, so there is no reason to give it this ability in the first place.
That completely ignores the anatomical differences between bipedal (human) and quadrupled (Tarrasque) creatures. The arms of the Tarrasque are not made for throwing things with accuracy. It would be surprised if the Tarrasque could even lift its arms above its head which is a requirement to throw something upwards or in a longer arc. So hitting something with a thrown object is very unlikely. And with all those uncertainties better stick to the rules which do not give the Tarrasque a throwing attack.
Yeah, you are right, that was a bad choice of word. I originally was going to say "hand" but though of including things with tentacles as well. So I chose appendages. Obviously a cat cannot pick anything up. But the artwork gives the Tarrasque much more hand to work with. It might not be great at throwing something, but losing its +9 proficiency bonus seems like a reasonable trade off.Have you ever seen a cat throwing a rock after a flying bird? Can you imagine a cat doing it (and hitting)? No? But it has appendages and as much hands as the Tarrasque has.
