STR 20, WIL 12, 8hp, Armour 3, Stare, Charge, Lizard Frenzy, Tail Strike, fast, sense of smell.

A giant, gray, eight-legged lizard with a flat crocodile head full of teeth. It has a visor made of brass bolted to its head, and a collar around its neck, just in front of the first set of legs. Wants food, warmth, to be free of the chain.

Unique Death Conditions: Unless the basilisk is completely burned, dissolved in acid, or separated from stone, a random stone larger than a fist touching some part of the basilisk's corpse has a 1-in-6 chance per year of becoming a basilisk egg and hatching in 1d6 years. Only one egg will be created in this way. The reincarnated basilisk grows to its original size+20% in a year, if well fed, and remembers its previous lives. Almost no one knows about this, but some wise old wizard, hearing the party's tale many years later, might lurch to his feet to warn them.

Stare (passive): The basilisk can only stare at targets directly in front of it unless its visor is removed. The effect has a 20' range. More than one target can be affected, but they must be very close together. Saves are rolled at the start of each round, before initiative order is determined. The effect is not reflected by mirrors. If the basilisk just glances at a creature, the only effect is a slight sensation of pressure. If it focuses on a creature for one round, the target's limbs become heavy, slow, and grey. Their thoughts move like treacle. The target must succeed on a STR Save to restore movement, or stay rooted in place otherwise. This effect ends immediately if the basilisk looks away. If the basilisk stares at a target for a second round, they must succeed on a second STR Save or turn to stone. If they pass, they are still rooted in place (as above). Saves rolled at the start of each turn.

Charge: The basilisk will try to charge partially petrified targets first, but if blinded or annoyed, it will charge almost anything. It moves twice its usual speed straight ahead, ignoring fallen pillars, and snaps at the target. It can maintain its Stare during the charge. If maded of stone, the target shatters and is devoured. If made of flesh, it takes  d8 Daamage and is knocked prone. If the target was not aware the basilisk was in the room they must succeed on a WIL Save or panic.

Lizard Frenzy: If surrounded or threatened, the basilisk thrashes wildly. All adjacent creatures take d6 damage and must succeed on a DEX Save or be knocked prone. The basilisk can't stare at a target this round.

Tail Strike: The basilisk does not like being flanked. While pretending to focus elsewhere, it whips its tail at a target for d8 Damage and is flung 10' in a random direction. Basilisk can maintain its Stare at a different target during this attack.

Basilisk Behavior and Other Information: as per the original.
