D&D 5E Mount Expansion
This supplement expands the options for mounted characters in 5e fantasy campaigns. It adds animal mounts, including new horse varieties, and horse-like monsters across a range of challenge ratings so steeds can remain viable from early to high-level play. It also includes mount templates and a concise set of feats that distinguish individual steeds and allow them to advance alongside their riders.
