All I know is that Tier 1 Elrues are used for upgrading weapons and armor from 0 to +3. Now someone answer my question in the other thread D:

from what i have tested, blessed ones are the best to refine your weapon, till today all the refines i did with blessed never failed, lucky ones are the 2nd best they give more chance of sucess but i already failed refining with them, and for last there are the normal ones that well... are just normal.
