While the stats look similar on the superficial level, you'll begin to run into problems when you expect a monster to be a threat to your characters, only to realize that its AC and attack bonuses are so low that the PCs can't miss it, and it can't hit them.įor example (picking a creature at random): in Pathfinder, an Ancient Green Dragon has an AC of 36 and an attack bonus of +31. Saves work differently, feats work differently, many monster abilities and effects work differently, etc. Pathfinder and 5e work on very different rulesets, including different methods of calculating attack, defense, and damage values, and different expectations of the PCs capabilities.
