I often hear about only last 3 lines of hones can be used by precise honing hammer. but from my experience in TW server awhile ago when it has event giving free hammers, every line of honing can be hammered except the 5 stats(STR,AGI,INT,WIS,VIT), no matter where they placed. and it was in different colour if you noticed, from what i had tried, orange colour can be hammered but yellow colour can't.
can VCRs test it in test server and give me a precise honing answer?
