I realise it's an out of print game, but we've only just gotten around to playing it and I can't work out where else I'd ask. (Here's hoping there's some 1st Ed veterans here.)
Can familiars (the Heroes have Boggs the Rat following them around) enter the water bits?
The card mentions Heroes and Monsters and familiars are neither.
I was thinking no, as the pit at the end of the stream can't kill the little sod, either.
