On the Italy server, world Dinegu, there is a level 187 Arc. Investigation showed that Arc has a bonus of 100% exactly (looking at the underlying metadata, not just the displayed percentage).What is the highest known level of an Arc anyway? The highest I was able to find is at 180, in Dunarsund.
Edit: I found it on foestats.com, not sure how often the info there is updated.
