Bardic Knowledge
At 1st level, a bard selects one Knowledge skill. He gains 1 bonus skill point to place in that Knowledge skill and an additional skill point every time he gains a level. In addition, a bard adds 1/2 his level (minimum 1) to all Knowledge skill checks and may make such checks untrained.
Bardic Performance
Once per day per bard level, a bard can use his Perform skill to produce magical effects on those around him (usually including himself, if desired). While these abilities fall under the category of bardic performance, they can be activated using any Perform skill, such as dancing, singing, playing an instrument, or performing comedy. Each ability requires both a minimum bard level and a minimum number of ranks in the Perform skill to qualify; if a bard does not have the required number of ranks in at least one Perform skill, he does not gain the bardic performance ability until he acquires the needed ranks. Some abilities
can only be used by a bard with a specific type of Perform.
