Decorations, sets, and masterworks

Ordinary decorations are free. Six masterworks cost Cheer. The FAQ names both the groups and the masterworks, and it says variety beats repeating one piece.

The store promises 100+ decorations and masterwork builds. The FAQ splits that into eight groups: trees, fences and arches, lights, ornaments, figures, market stalls, village details, and winter fun. Pieces inside those groups are not named one by one. A set-completion achievement cannot be turned into a checklist until those names exist in public.

Wonder and Santa Magic

Decorating raises Wonder. Wonder adds up to 15% more Santa Magic at the end of the year. A mix of pieces counts for more than repeats. There is no time-of-day slider at launch. Day and night cycle about every 10 minutes. Pause holds the current light, so you can freeze sunset or full night while you place bulbs.

Cheer itself comes from elf-life buildings near homes: Hearth, Cocoa Hall, Elf Plaza, Skating Rink. They raise Cheer each week. The FAQ does not give a Cheer price per masterwork.
