So I got a copy of Small World, and in our first game, the "Amazons" came up early. According to the rules, they get "+4 when attacking". What exactly does that mean? We argued it out and what we eventually decided it meant was
At the beginning of each of the Amazon player's turns, they receive 4 extra tokens. When they end their "conquering regions" step, they remove 4 tokens of their choice from the board, then go on to compute VP.
But we're not at all confident in our interpretation.
