I've discovered a way to infinitely duplicate the Arcane Enhancer: Stage 3 item used in enhancing the explorer gear (and eventually awakening into hiram gear).
Requirements:
1 Unique Brilliant Explorer's 2H weapon
1 Heroic Radiant Explorer's pants (can be cloth, plate, or leather)
(There are other combinations of items this can be done with, these are just the 2 I'm using in this example)
Step 1. Break both items down using 2 Beginner Catalyst Stones. This will result in 6 arcane stage 3 enhancers, 9 rare stage 2 enhancers, and 3 grand stage 1 enhancers. It will also give back 1 rare equipment awakening scroll, and 2 grand equipment awakening scrolls.
-- 6 purple, 9 blue, 3 green left --
Step 2. Buy a new 2H weapon from a weapon vendor. Use 2 Grand Enhancer: Stage 1's to enhance the weapon from basic to arcane. Awaken the 2-hander to the grand radiant level using one of the grand equipment awakening scrolls.
-- 6 purple, 9 blue, 1 green left --
Step 3. Continue enhancing the 2H from grand radiant to heroic radiant using 5 rare stage 2 enhancers. Awaken the 2H to rare brilliant using one of the rare equipment awakening scrolls.
Up until now, this is the normal enhancing route that players take. This is where it deviates.
-- 6 purple, 4 blue, 1 green left --
Step 4. Enhance the 2H to unique brilliant using 4 Arcane Enhancer: Stage 3's and 2 Rare Enhancer: Stage 2's.
Note: Normally, this would be 6 Arcane Enhancers, since 5 arcane enhancers leaves you short by 8 exp. However, you can replace 1 Arcane enhancer (250 exp), with 2 rare enhancers (130 exp each or 260 exp total). This will allow you to reach cap without using up all of your Arcane Enhancer: Stage 3's.
-- 2 purple, 2 blue, 1 green left --
Step 5. Buy a new pants armor piece from an armor vendor. Enhance it from basic to arcane using 1 Grand Enhancer: Stage 1. Awaken the pants to grand radiant using the 1 remaining grand equipment awakening scroll.
-- 2 purple, 2 blue left --
Step 6. Enhance the pants from grand radiant to heroic radiant using 2 Rare Enhancer: Stage 2's, and 1 Arcane Enhancer: Stage 3. (This is also abnormal since it should be 4 rare enhancers here).
-- 1 purple left --
Step 7. Repeat steps 1 - 6.
As you can see, following this process nets you 1 additional arcane enhancer each time. Now, as far the impact of this, it's pretty straightforward. Choosing to enhance a 2H instead of 2 1H weapons leaves you with a spare set of awakening scrolls (since you only needed one set for a 2H).
Normally, those scrolls would be useless (as they should be), but with this method it allows a player to get an additional piece of hiram gear or even a second 2H for nothing more than the gold and labor cost of enhancing a vendor item.
An easy way to fix this: restrict each enhancer's application to the relevant tier of explorer's gear. The awakening scrolls are already restricted this way. Making this fix also prevents new players from messing up the enhancement ordering and using a purple when they should have been using a green (thereby screwing themselves over).
