Guild Wars 2

Niith.9274:

If I’m going for the leaf of kudzu, can I only get that by combining 4 longbows, or will any rares do?

If you want something specific, you need to use exactly that weapon type. If you have anything mixed (including with Mystic Forge stones) the drop will be random.

If you want leaf of kudzu throw in longbows. Or buy it from the TP.

These threads always make me want to try throwing crap into the forge.
