TODO: Change Wisps' level

[GizzleBizzle]

The earliest GoblinWorkshop archive from 20.10.2004 describes Wisps at lvl 15.

There are three Wisp screenshots in the Archive, all of them at lvl 15.
0.5.5/early 0.6 | 210c2cf8f8fce1f0
0.5.5 | 7f7f7f2880800000
0.9-0.10 | d3ccfc7c0020fe7f

SPECULATION
The following snapshots of GoblinWorkshop show Wisps at a lvl 1-15 range. Perhaps it was changed later or the previous data was incomplete.

It would be best to set Wisps' level at 15 and wait for any other screenshots come up. Finding an alpha/beta screenshot with a different level would mean they indeed had a level range, however current evidence is strong for a flat lvl 15.
