KE has tweaked the BUS percentages on items that are now considered high class
To upgrade high class items (e.g. tier 5 and 6 armor, iron bow, raptor): HUS-BUS-BUS-BUS-BUS-BUS-BUS. The aion kinah % for those steps are approximately 99-100-70-75-55-25?-5. HUS is unreliable for upgrading past +2.
At this time I do not have a sizable sample size for 6->7 so the % is a guess. If you want to be conservative, use BUS from 1->2 instead of HUS. Conclusions:
You can safely upgrade low class items with LUS to +3
You can safely upgrade mid class items with MUS to +3
You can safely upgrade high class items with BUS to +3
KE has tweaked the BUS percentages on items that are now considered high class. 3->4 is now 70% (it was 90% pre-KE) and 5->6 is now 55% (it was 45-50% pre-KE)
It doesn't seem to help to use MUS, HUS, or BUS on a much lower grade item. E.g. using MUS on a low class item from 5->6 or 6->7 doesn't seem to improve the % success compared to LUS, and MUS costs than LUS more.
The same applies to using HUS on a middle class item from 3->4 or 4->5 compared to MUS, and to using BUS on a middle class item from 7->8.
For enchanting or adding elemental: LEnS and LElS are reliable on low class items, and MEns and MElS are reliable on middle class items. The % of failure is very low.
