The subject gains a +2 enhancement bonus to Diplomacy checks. The enhancement bonus increases to +4 at 5th level and +6 (the maximum) at 9th.

     Notes: Compare to jump. 10x the duration, 1/5 the effect (doesn't seem like a fair tradeoff, except that since bonus values in d20 increase in value by squaring rather than linearly. Something to give a little boost to the diplomat in the group, or to counteract a character with low Charisma.
