I didn’t notice that base when I first looked at the picture. Is it to stay compatible with the 20mm wide bases that elves use in some rules (or keep compatible with a collection where earlier figures were based that way), but accommodate longer than 20mm puddle base? Reaper figures can be a challenge that way, they vary in size and their cast on bases often are to fit the pose rather than and specific dimensions. In any case, the figure looks amazing.
