In Dungeons & Dragons, a basilisk’s eye is the source of its petrifying gaze, a supernatural ability that turns creatures to stone if they meet its eyes. The exact mechanics are detailed in the monster’s stat block, and they involve a Constitution saving throw against a DC that varies by the basilisk’s version.
What the Basilisk’s Gaze Does in D&D
The basilisk’s gaze is a legendary monster feature that forces any creature that starts its turn within 30 feet of the basilisk and can see it to make a Constitution saving throw. The DC is typically 12, as seen in the Monster Manual (5e). On a failed save, the creature begins to turn to stone and is restrained. The creature must repeat the saving throw at the end of its next turn; if it fails again, it is petrified permanently. If it succeeds on the second save, the effect ends and the creature is no longer restrained. A successful first save means the creature is unaffected for that turn, but it must continue making saves each turn it remains within the gaze’s range.
This is a classic example of a “gaze attack,” a mechanic that has appeared in D&D since early editions. The basilisk’s gaze is distinct from a medusa’s, which also petrifies but has different range and saving throw details. In 5e, the basilisk’s gaze is a purely magical effect, not a poison or disease, so abilities like lesser restoration don’t work on the petrified condition; you need greater restoration or a stone to flesh spell.
How to Avoid the Gaze
Players have several options to protect themselves, and clever tactics are often the key to surviving a basilisk encounter. The most direct method is to avoid eye contact entirely. The rules state that a creature that is “blinded” or that “avoids looking at the basilisk” does not need to make the saving throw. This means you can fight while closing your eyes, but then you attack with disadvantage and the basilisk has advantage on attacks against you. A common workaround is to use a mirror or a polished shield to look at the basilisk indirectly, but the rules are ambiguous on whether this works; many DMs rule that the reflection still triggers the gaze, while others allow it. Another option is to cast blindness on yourself or use a fog cloud to obscure vision, but the basilisk can still see you if it has blindsight or truesight.
In older editions, the basilisk’s gaze was often described as a line of sight that could be blocked by walls or cover. In 5e, the range is 30 feet, so staying farther away is a simple solution, though basilisks are not particularly fast (speed 20 ft.), so kiting is possible. A greater restoration spell or a stone to flesh scroll is essential for any party planning to fight one, as petrified allies are otherwise permanently lost.
Basilisk Variants and Their Gaze
Not all basilisks are the same. The standard basilisk in the Monster Manual is a challenge rating 3 creature, but other versions exist across D&D supplements and editions. For example, the abyssal basilisk in Mordenkainen’s Tome of Foes has a similar gaze but with a higher DC (14) and additional demonic traits. The greater basilisk from Tales from the Yawning Portal is a larger, more powerful variant with a DC of 16. In earlier editions, such as AD&D, the basilisk’s gaze was often a save vs. petrification, and the creature’s eye color could vary, with some having a gaze that worked through reflections. The dracolisk, a dragon-basilisk hybrid, also has a petrifying gaze, often with a higher DC. When running a basilisk, DMs should check the specific stat block for the DC and any additional effects, such as the abyssal basilisk‘s ability to summon demons.
How to Run a Basilisk Encounter
For Dungeon Masters, a basilisk encounter is a tactical puzzle. The monster is slow and has a low AC (12), so it relies on its gaze to protect itself. A good encounter design involves placing the basilisk in a lair with plenty of cover, like a maze of statues (which are actually petrified victims). This creates a horror-movie feel: players must decide whether to look at the monster or risk being ambushed. The basilisk’s lair action in 5e allows it to create a minor illusion or cause a tremor, which can be used to herd players into its line of sight. A DM might also include a puzzle element, such as a mirror that reflects the gaze back at the basilisk (though this is not in the official rules, it’s a common house rule). Remember that the gaze only affects creatures that can see the basilisk, so a character who is blinded (e.g., by a spell) is immune, but they also can’t see the basilisk’s attacks. This creates interesting trade-offs.
Common Misconceptions About the Gaze
One common mistake is thinking that the basilisk’s gaze is a single attack that requires an action. In 5e, it’s a passive effect that triggers at the start of a creature’s turn, not an action the basilisk takes. Another misconception is that you can simply look at the ground and be safe; the rules say “avoiding looking at the basilisk,” which is a narrative decision, but the DM decides if that’s enough. Some players assume that a mirror image spell creates illusory duplicates that the basilisk might gaze at, but the spell doesn’t specifically interact with gaze attacks, so the DM must rule. Also, the petrified condition is not permanent by default; it lasts until the effect is removed, but the basilisk’s gaze doesn’t automatically end after a successful save—it’s a continuous effect each turn. Finally, a basilisk’s own gaze does not affect itself, as it is immune to its own petrification (as stated in the stat block).
Basilisk Eye as a Treasure or Component
Some players wonder if a basilisk’s eye has magical properties beyond its gaze. In the official rules, there is no standard rule that a basilisk eye can be used as a spell component or to craft a magic item, but many DMs create such uses as homebrew. In the Dungeon Master’s Guide, there is no listed item for a basilisk eye, but the petrified condition can be reversed with stone to flesh, which requires a drop of blood from a basilisk as a material component (though this is not explicitly stated in 5e; the spell’s component is a drop of blood from a humanoid, not a basilisk). In older editions, such as AD&D, a basilisk’s blood was sometimes used in alchemy, but this is not official. If you want to use a basilisk eye as a plot hook, you can have a wizard pay handsomely for one, but the rules don’t support any inherent magical power beyond the gaze itself.
Basilisk vs. Medusa: Gaze Comparison
The basilisk and the medusa are often confused because both petrify with a gaze. In 5e, the medusa’s gaze is similar but has a shorter range (30 ft.) and a higher DC (14). The medusa’s gaze also has a different mechanic: it forces a saving throw at the start of the creature’s turn, but the medusa can also use its action to force a creature that is looking at it to make a save immediately. The basilisk’s gaze is more passive, while the medusa is more aggressive. Also, a medusa can control its gaze to not affect allies, but a basilisk cannot—it affects all creatures that see it, including its own allies if they are within range. In folklore, basilisks are often called “king of serpents” and are hatched from a rooster’s egg, while medusas are humanoid with snake hair. In D&D, they are separate creatures with distinct lore.
Frequently Asked Questions
Can you avoid a basilisk’s gaze by closing your eyes? Yes, if you are blinded or choose to avert your eyes, you don’t have to make the saving throw. However, you then have disadvantage on attack rolls against the basilisk, and it has advantage on attacks against you, so it’s a trade-off.
Does a mirror work against a basilisk? The rules don’t explicitly cover reflections. Many DMs rule that looking at a reflection still counts as seeing the basilisk, so the gaze works. Others allow it as a clever workaround. Check with your DM.
How do you cure petrification from a basilisk? The greater restoration spell or a stone to flesh spell can end the petrified condition. A potion of stone to flesh also exists in the DMG. Without these, a petrified character is effectively out of the game.
Is a basilisk’s gaze a magical effect? Yes, it is a supernatural ability, but it is not a spell. It can be dispelled by dispel magic only if the DM rules it as a magical effect, but the stat block doesn’t label it as such. In 5e, it’s considered a monster ability, not a spell.
