Shackles of Blood is an interesting adventure, some may be interested to play in it because of the introduction or summary that offers a bit of mystery. For me, this module is good because it introduces the characters to events that explain the situation in Hillsfar. The introduction hook is good because it lets the character get invested in solving the mystery. Has a bit of roleplay and investigating to keep up the mystery which is good, a lot of combat that will please anyone that is into action. However, a word of warning. There is a lot of combat in this adventure but the combat is deadly for low level characters or players that are new to the game. It's weird that this is one of the early adventures in the Rage of Demons story line but the combat included here is deadly for low levels and can actually lead to a character dying if they don't do the battle well. Overall, I would recommend this adventure to players whi are more experienced and familiar in Dungeons and Dragons.
