Traits
Magic Resistance. The marilith has advantage on saving throws against spells and other magical effects.
Magic Weapons. The marilith's weapon attacks are magical.
Reactive. The marilith can take one reaction on every turn in a combat.
Actions
Multiattack. The marilith makes seven attacks: six with its longswords and one with its tail.
Longsword. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage.
Tail. Melee Weapon Attack: +9 to hit, reach 10 ft., one creature. Hit: 15 (2d10 + 4) bludgeoning damage. If the target is Medium or smaller, it is grappled (escape DC 19). Until this grapple ends, the target is restrained, the marilith can automatically hit the target with its tail, and the marilith can't make tail attacks against other targets.
Teleport. The marilith magically teleports, along with any equipment it is wearing or carrying, up to 120 feet to an unoccupied space it can see.
Reactions
Parry. The marilith adds 5 to its AC against one melee attack that would hit it. To do so, the marilith must see the attacker and be wielding a melee weapon.
A marilith is worth 15,000 XP. Using the 2024 encounter budgets (SRD 5.2), this is how many mariliths fit each difficulty for a party of four characters of the same level. A dash means even one would be over the budget.
Budgets add up every monster’s XP, so you can swap some for other creatures of the same total. Try other party sizes and mixes in the encounter calculator.
Against the 4 other challenge 16 monsters in the SRD 5.1, the marilith has more hit points than 0 of them, which makes it one of the frailest at its CR. See every CR 16 monster.
