All seasinger's items give 3 oceanic components each, meaning that the cheapest items to disassemble for them is either the inferior hood (tradeable, 30 chi), or superior aonori or asari (untradeable, 20 chi each). Alternatively, level 9+ augmented seasinger's robe bottom (60 chi) give 12 oceanic components when disassembled, at the additional cost of an augmentor and the time (and divine charges) spent levelling them up.
