I want to preface by saying I've been searching for a while and can't find any data on the subject... So I thought I'd pose the question here.
I've been gearing up thf for the first time and trying to figure out the treasure hunter cap stuff. It seems like there is a debate between whether or not your base TH caps at +8 or just your first hit caps at 8. After that I've read that the difference in your TH level and the level of the mob affects proc rate, but it's unclear (or maybe just unsolved) as to whether or not being higher than +8 yourself will increase the proc rate.
Has anyone seen any solid testing data on this? It seems like it should be pretty easy to test if you have the parsing/lua skills (Not sure I do or not). It's weird to me that thf weapons and hands from dynamis are on the more expensive side if higher TH doesn't matter, since you can easily cap without them.
I guess the armlets could be a decent TP piece, and with +4 there you only need one Herc piece with TH to have yourself capped TH on a good TP set with any weapons you want... That could make them desirable... I don't know.
