"Feather Fall" (PH, p. 239) says:
Choose up to five falling creatures within range. A falling creature's rate of descent slows to 60 feet per round until the spell ends. lf the creature lands before the spell ends, it takes no falling damage and can land on its feel, and the spell ends for that creature.
Facing a 500' series of continuous underground waterfalls (but not a straight vertical drop), my players cast Feather Fall and leaped in. This raised a number of related questions:
- Does the water push them down faster than Feather Fall allows? (60'/rnd)
- Do they take damage from bouncing off of rocks, or do we assume that moving at just 60'/rnd, the damage is mostly avoided?
- Do they tumble around in the air due to the water pushing them? ie. it would be difficult to shoot range weapons or cast spells?
- Are there any other relevant factors to this scenario that I'm not thinking of?
My first thought at an answer is that the water and player are both falling (vs. the water pushing them), so they "float", and when the player hits a rocky outcropping, it is considered "landing" (no damage) at which point they aren't falling anymore and the water immediately pushes them off, at which point they are falling once more. I'm not sure about tumbling around.
