How this board opens
The overlap rule is stingy here: one sweep of it across every row and column yields 52 of the 225 cells, 23%, so most of this board has to be argued for rather than read off. The most generous opening is row 15, which gives up 15 cells on its own. 3 of the 30 lines are decided outright by their clues, with no room to slide. Straight line logic carries it to 95 cells and then stalls, so the last 130 need cross-referencing between a row and a column that share a cell. The finished picture fills 71 cells, and the longest unbroken run anywhere in the clues is 9.
About this category
Symbols, vials, and half-finished experiments — the alchemy set leans into the visual clutter of a wizard's workbench, which turns out to be a good fit for nonograms: lots of small internal detail means real clue interplay between rows and columns, not just one big blocky silhouette. Most of the set sits at 15×15, the size where cross-referencing actually starts to matter, with a couple of full 20×20 boards for anyone who wants a longer sit-down solve and a few 10×10s at the gentler end.
