From publisher blurb:
The Lazy GM brings our classic range of ready-made monsters to 5th Edition.
Within are hundreds of stat-blocks for thirty nine classic monsters, from Aboleth to Xorn, with a range of builds to suit all challenge levels. Using the freedom and flexibility of the 5th Edition, building on our earlier work, we bring updated versions of old favourites like the Manticore Mercenary, Otyugh Crime Lord and the Tiny Mimic, and bring all new exciting foes like the Jack O’ The Green, Gold Xorn Transmuter, and the Kumo Forest Spider Shaman.
Inside you’ll find extraplanar variants, environmental variants, fey versions, undead versions, half-dragons and a whole host of unique twists on classic D&D monsters, all ready to drop straight into your game.
From the CR 1/8 Zombie Rat to the CR 23 Epic Purple Worm, fully clickable index cross-referenced by CR, templates and monster roles to easily find what you need.
