Hi everyone! I would like to upgrade a blue weapon I found, and did so up to level 3. I have some anvils left, can I know at what level will the upgrade success stop being guaranteed? As in, is there a diminishing rate of success after each upgrade?
Thanks in advance!! 
It’s 100% all the way up to +5. Then after that it is as follows:
+6 | 88%
+7 | 78%
+8 | 68%
+9 | 59%
+10 to +15 | 51%
Whereas the armor success rate drops off after +3.
Weapons up to +6 seem fine so far, very low fail rate at that point (the normal is +5 with no failure), armor i do +5, i don’t remember any of my armor pieces failing up to +5.
Okie, thanks!!!
This guy has it right, also when in doubt these numbers are on tosbase.
Main hand’s are safe till +5 on the other hand Daggers are only safe till +3 (see what i did there)
Took me a second… lol
