Basically, I'm playing a water genasi druid, and I'd hate to have a -12 penalty to my swim checks (even with the +8 bonus) because of armor (double the -6 for banded mail). I'm looking for some officially published ability that is the equivalent of a +1 bonus (making the armor total +3000 gp or a +2 modifier)
edit: I found this:
Plate Armor of the Deep
This +1 full plate is decorated with a wave and fish motif. The wearer of plate armor of the deep is treated as unarmored for purposes of Swim checks. The wearer can breathe underwater and can converse with any creature with a language that breathes water.
Moderate abjuration; CL 11th; Craft Magic Arms and Armor, freedom of movement, water breathing, tongues; Price 24,650 gp; Cost 17,150 gp + 600 XP.
since I don't want full plate, and don't need to breath underwater, can we seperate out some of that cost? This is exactly what I want, except not plate mail.
