Hello, I have a question to use regurgiatate ability from a purple worm.
A regurgitated creature takes falling damage from the height of the target or from 20 feet, whichever is greater.
1/ 10 bludgeoning damage from 20 feet. Height of the Target : Huge, Gargantuan ? Damage ?
2/ Doesn't An Unbreakable-er Goblin take falling damage with regurgitated ability ? And the target ?
Same question with a character using rolling landing feat.
3/Are there means to resist or prevent damage from swallow ability ? (bludgeoning damage) -> resistance bludgeoning damage or physical attack ?
4/ Is it possible for a character to be swallowed automatically by a creature ?
For example, if it's a trained animal with train animal feat ?
Thanks for your future answer.
1) Target height doesn't matter for falling damage.
2) The fact that the worm is spitting you out doesn't change how the fall damage works. All abilities that change fall damage work normally.
3) Resistances applies normally to Swallow Whole damage.
4) I don't understand this last question? You are talking about a willing target allowing to be swallowed? If is this there's no rules about this but many GMs allows that willing target choose to fail in their saves but the monster still need to use actions grab and Swallow Whole.
1) The way that I am reading the Regurgitate ability, the 'target' in the last sentence is the target of the strike.
So if a Purple Worm regurgitates a rock at a human, the rock isn't a creature and so that last sentence doesn't trigger.
If a Purple Worm regurgitates a cave spider at a human standing on the ground, then the cave spider takes damage from falling the height of a human or 20 feet whichever is higher. Since a human is normally 5 to 6 feet tall, use the 20 feet for the fall damage applied to the cave spider.
If a Purple Worm regurgitates a human fighter at a wizard that is flying 45 feet in the air launching spells, then the human fighter will take falling damage from the 45 feet height of the wizard or 20 feet whichever is higher. Since the wizard is flying, use the 45 feet fall distance.
2) Yes, you can use your abilities that reduce or eliminate fall damage if you happen to be the one regurgitated at a different target. That won't change the amount of damage that the target takes from the Regurgitate ability. Your ability to reduce fall damage also won't reduce the damage from being hit by a regurgitated rock or creature if you are the target of the Purple Worm.
3) Yes, you can resist the bludgeoning damage from Swallow Whole. That won't change the other effects of being swallowed such as having the Grabbed condition, Slowed 1, and having to hold your breath.
4) There really aren't any solid rules for voluntarily being affected by attacks from an ally that generally require attack rolls. Common rulings are that it is allowed to voluntarily fail, or that the attack/defense is still rolled but the target can voluntarily reduce the degree of success by one stage.
