This set includes twenty-six tiles, including one online bonus tile; one more tile is available in the revised version of A Dozen Dungeon Hazards. This is a very useful set even if you don't care to use the scarlet mold hazard as such. The first twenty tiles feature scarlet mold growing in a variety of settings?half dungeon, half cavern. Several of the dungeon tiles are basically repeats from earlier sets, with scarlet mold added, though a couple are new, and most of the cavern tiles feature new layouts that interface beautifully with earlier sets. Three of the cavern tiles feature flooded areas, and three are multi-level. Tiles 21 through 25 reproduce other tiles in the set, but without the scarlet mold. The set also includes trimmable tiles of crimson fog (produced by the mold) that you can cut into any shape you need.<br><br><b>LIKED</b>: Everything.<br><br><b>DISLIKED</b>: Well, more tiles would always be great, but this is a really fine set.<br><br><b>QUALITY</b>: Excellent<br><br><b>VALUE</b>: Very Satisfied<br>
