By filling your spiritual center with the weightlessness of Bismarck, you gain the ability to swim normally when you couldn’t.
Prerequisites: Knowledge (Religion) 3 ranks, Swim 1 Rank.
You gain a Swim speed equal to half your land speed. If you already have a swim speed, it increases by half your land speed. For every 5 ranks in Knowledge (Religion) you have, your swim speed increases by 5 ft. In addition, when you reach 10 ranks in Knowledge (Religion), you gain a fly speed (average maneuverability) equal to half your swim speed and can use your ranks in Swim for Fly checks. You cannot use this feat in a region or plane of existence that does not worship or have heard of Bismarck.
