This section offers a selection of common monster powers you can apply to any quick-build monster to give them a stronger mechanical flavor, make them more tactically interesting, or reinforce their behavior in the story of your game.

This creature adds +3 to their Armor Class against one melee attack that would hit them. If the attack misses, this creature can immediately make a weapon attack against the creature making the parried attack.

This power works well for clever foes, especially those who are experts in the use of the weapons they wield.

When a target this creature can see (including themself) either succeeds or fails on a saving throw against a spell or other magical effect, this creature can expend a spell slot to force the target to reroll the saving throw.

Appropriate for a powerful spellcaster, this power represents mastery over magical forces in its ability to enhance or weaken a spell’s effect.
