Eric WagonerandClaude Fable 5.1 bc99ee3eb7 Attacks aimed at a bush or the ooze: five points clear the square
A THORNBUSH or ROSEBUSH "will be destroyed" by five points of damage,
and the FAQ lets only fire hurt a KILLER OOZE; the table refused every
attack aimed at one. An attack tapped onto a bush or ooze now lands on
it, the damage accumulating across attackers and turns, and the
fifth point clears the square. A WIZARDBLADE is swung from the square
beside it, as its text asks of a target that fills a square.
