10 Monster Feats
A collection of ten feats designed primarily for monsters, replacing feats normally listed on creature stat blocks. The options enhance unusual abilities and combat traits, allowing creatures to send opponents flying, withstand more damage, extend special attacks, move safely, pull foes with tendrils, or knock enemies down with a shockwave. Other feats improve attacks of opportunity, enable rapid assaults with natural weapons, or allow spellcasting while taking other actions. The material presents each option briefly, with minimal explanation for integrating them into a campaign.
