You get these via Limbus and of course meaning you have to have Sea access from Chains of Promathia. I've been doing limbus a longass time and I finally decided to finish out an AF+1 set so I chose THF.
It took several months to finish this set due to the mats never dropping a lot but I finally got 5/5 AF+1 for my THF and I'm very happy. I do admit I get some funny double-checks from people when I'm afk.
I'll probably do DRK next on AF+1 seeing as I usually have a ton of coins because it's a bother to sell them and I just would rather do something with the coins i earn in my runs.
P.S. Outside of the hands for EXP with the added TA choice there really better options for gear as a THF. Get this set with the understanding that you're getting it for Jeuno/Whitegate posing.
