I'm pretty sure most of you know this already, but just throwing it out there for the people who don't.
HLB CAN be made with Carpentry at G15S3, but there's a catch.
1) Player must be Merchant Destiny (Well, not too big of a problem here)
2) Following Material is needed:
Finest Leather x1 (LOL)
Large Nail x10 (wack some snowmans)
Finest Firewood x10 (Chop chop chop)
Shiny Tough String x5 (Haha, that's eas... WHAT THE HELL?!)
So what the eff is this "Shiny Tough String" needed to make HLB like crazy?
Quite unfortunately for some of the lower leveled players, this material is ONLY obtainable from "Advanced Hardmode" Dungeons. Players of Mabiabout reported that this material was most common in the Rundal Advanced Hardmode dungeon, but also obtainable from Alby Advanced Hardmode, and Ciar Advanced Hardmode.
Fortunately, however, the success rate of making the bow seems to be on the high side, as the player from the source reported 90%+ success rates for making this bow.
Discuss. Will you hunt for this item? It's not like you can spam the dungeon that easily, so I would expect the price to be a bit high...
If you're wondering about the Arbalest requirements, I'll post it up on request.
Mods, if this thread is in the wrong place, I would greatly appreciate it if you can move it.
