From 8ba0a934ccb152f59d9ed4aa19cd0fb5eb2b15b6 Mon Sep 17 00:00:00 2001 From: Eric Wagoner Date: Sat, 29 Aug 2026 00:17:32 -0400 Subject: [PATCH] The goat charges on legs, not wings (rules rev 10) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Eric's table ruling: BUTT-HEAD's ram IS movement — the charge walks real corridors on the turn's legal legs (three plus numbers played) and spends them, with the walked distance as the damage. The engine allowed an unlimited-range homing goat, and game thirteen ended on an eight-square ram its own caster ruled illegal. At rev 10 the cast refuses beyond-reach targets up front, a victim who slips away leaves the goat winded ("outran"), and the legacy test pins the old behavior at rev 9 for the ledgers that recorded it. The skill also gains the passivity audit: a turn that only draws is a lost turn.
