"The damage that a club does is based on the user’s ST. Refer to the Combat with Bare Hands, Daggers, Cestus, or Club table (below). The damage shown on that table, plus 3, is the damage a fighter with a club does in regular combat. If the club is used two-handed, as a maul, add 4 instead of 3."

In Death test 1, the Giant, at the end, PP 161 does 3+3 with his club, i.e. the damage of a Battle Axe +3. According to the table, if the damage was based on strength alone (with no weapon skill) the damage should be 1+6. There is your difference. A trained fighter will do the damage according to the weapon table using a club, while an untrained fighter will do damage according to the ST table."

The spell Summon Giant brings an ST 30 giant who does 3d+3 with club. But in the rules for damage with a club where giants are discussed (pg. 122), ST 30 lines up with 1d+6 (one-handed) and 1d+7 (two-handed). Summoned giants wield clubs with extra gusto?
