Details:
Attempting to break the latent on Sword of Trials, to complete the quest Inheritance, I used Dimidation as it produces a light skill chain when paired with itself. This however failed break the latent or impact the weaponskill points needed at all, I performed well over 50 Light skillchains. after talking with my ls i decided to switch to Hard Slash and repeated for 300 weaponskill points checking after every 5 ws to see if the latent had broken, it finally broke when i reached the 300 point mark as if i had not done a single ws before starting the hard slash spamming. This to me shows that Dimidation does not count for weaponskill points i believe it to be a small over sight that it was not added to the list when it was created i have not tested it yet but i would think this same bug exists on the GEO ws Exudation
