okay actually, from my playing this game for a week, i have figured out the following
1) Enhancement of epic has a reset-to-lv3-chance starting lv4, and a breaking chance starting lv7
2) Using code to add potential has no breaking chance.
3) Prefix is done from the blacksmith to add prefix.
So my question is, lets say i want to make an epic item to level 6, with a hidden ability, and with a prefix,
say a destruction +6 immortal cannon with ATT +6%
is the order of things are important? Should i enhance first, or should I prefix/hidden potential first?
I started playing after the dragon jades are implemented, so I'm not quite sure about prefix. But, the order
Of things do not matter. You can just enchant first or slot a jade first. Doesn't affect one another. Currently I don't think new items has hidden potential anymore except for those unique and legend grade items. Epic and below can only get extra stats trough jades. I might be wrong though.
