If your attack succeeds, make a Strength check opposed by the defender’s Dexterity or Strength check (whichever ability score has
the higher modifier). A combatant gets a +4 bonus for every size category he is larger than Medium or a –4 penalty for every size category he is smaller than Medium.
小体型绊摔-4的。。不骗你。。而且发动的一方必须用力量对抗,只有被摔的一方可以选较高值。。= =
所以你要摔别人加值就是 -1力量+(-4体型)+4专长 = -1。。。
