How do I model a PC being swallowed by a dragon in D&D4e?

Question

I recently read of an attempted dragon-slaying strategy, which involved a magic-user getting swallowed and then summoning Tenser's Floating Disc.

Besides all of the other problems with this setup, I'm wondering, how would the swallowing be modeled? How long can a PC survive inside the stomach of a dragon, under D&D4e rules?

Answer 1

Swallowing has been modeled in D&D 4e on other creatures. You should be able to adapt one of them to the dragon just fine. For example, the Purple Worm ^DDI

Swallow (standard, at-will)

The purple worm tries to swallow a bloodied Medium or smaller creature it is grabbing; +21 vs Fortitude; the target is swallowed.

• The swallowed target is inside the purple worm and is dazed and restrained until it is no longer swallowed.
• The swallowed target has line of sight and line of effect only to the purple worm
• No creature has line of sight or line of effect to the swallowed target.
• The only attacks the swallowed target can make are basic attacks.
• At the start of each of the purple worm’s turns, the swallowed target takes 10 damage plus 10 acid damage.
• When the purple worm dies, the target is no longer swallowed and can escape as a move action, appearing in the purple worm’s former space.

(I reformatted the quote a bit to make it more readable)

Answer 2

You could assign a fire|cold|poison|etc-based ongoing damage based on the dragon's type, plus a fixed starting damage due to munching, plus, perhaps, some rolls to endurance to simulate the difficulty of performing a summoning while being digested.
