The choke creeper, or strangler vine, is a long, thick vine with many branch vines, each capable of attacking. The vine is olive green in color, and the main vine is almost 1-2 feet thick. Branch vines have flexible tendrils, allowing them to creep at 5 yards per round. They are attracted to light and heat.

For each 20 feet of main vine, it has the 1 hp per HD; branch vines have 2 hp per 20 feet of the main vine (branch vine hit points are in addition to those of the main vine, not part of the total). In each 10-foot section of the main vine, there are four branch vines. The smallest choke creeper is 20 feet long, has 1 hp/HD (25 hp total), and has eight branch vines, each with 2 hp. The largest choke creeper is 160 feet long, has 8 hp/HD (200 hp total), and has 64 branch vines, each with 16 hp. The main vine is AC 14, the branches AC 13.
