Divine intervention when the Cleric is dead...and level 9

[Andrew Hackard]

You only stay dead until the start of the next player's turn, so your daughter was 100% correct.

In the VERY unlikely event that DI had come up on the same turn that she died, she could not level up to win the game.

Both of these rules are found in the rulesheet for your game under "Death" (usually on p. 4 or 5).
