For all you SMNs who are thinking about meriting Shattersoul, i've just been doing some tests with shattersoul inside and outside abyssea, not much tho

from what ive witnessed on too weak outside abyssea it does around 500-1000 dmg.

inside abyssea (and ive tested with all kinds of atmas) it usually deals around 1000-1500 damage on la theine sheep and gives ruby light upon killshot
