Unarmored Defense. The segua adds her Constitution modifier to her AC (included).
Alluring Presence. As a bonus action, the segua can target one creature that she can see within 100 feet of her. The target must succeed on a DC 15 Wisdom saving throw or become charmed by the segua until the end of the segua’s next turn. On subsequent turns, the segua can use her bonus action to maintain this effect, extending its duration until the end of her next turn. The effect ends if the segua and the creature are ever more than 100 feet apart from each other, if the creature can neither see nor hear the segua or if the creature takes damage.
Once the effect ends, or if the creature succeeds on its initial saving throw against this effect, the creature is immune to this segua’s Alluring Charm for 24 hours.
Multiattack. The segua makes two slam attacks.
Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage.
Illusory Appearance. The segua covers herself and anything she is wearing or carrying with a magical illusion that makes her look like another creature of her general size and humanoid shape. The illusion sends if the sega takes a bonus action to end it or if she dies.
The changes wrought by this effect fail to hold up to physical inspection. For example, the segua could appear to have smooth skin, but someone touching her would feel her rough flesh. Otherwise, a creature must take an action to visually inspect the illusion and succeed on a DC 20 Intelligence (Investigation) check to discern that the segua is disguised.
