Legendary Dexterity 1/day. If the Arachnid fails a Dexterity saving throw, it can choose to succeed instead.
Siege Monster. Attacks do double damage to objects and structures.
Crawling Eyes. The Arachnid has eight eyes that seem to slide along its body to wherever they need to be, completely independent of each other. If these eyes are targeted, their AC is 20 instead, and the resistances listed are changed to vulnerabilities, but radiant becomes a resistance. If any one eye takes 15 damage, it bursts into smoke, and disappears. It has eight eyes at the beginning of the fight regardless of how many were burst while it was a Void Dragon.
Frightful Presence. Upon first seeing the Arachnid, each creature of the Arachnid's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 15 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.
Cornered Multiattack. This creature can make 2 attacks for as many creatures are adjacent to it, max 8 attacks.
Action Melee Attack. Melee Weapon Attack: +11 to hit, reach 5 ft., 1 target. Hit: 4d8+4 slashing damage.
Two Birds One Stone. When this creature makes an opportunity attack, it makes two.
The Arachnid can take one legendary action per turn.
Wall Wreck. It makes an attack on a wall, destroying it on a hit. Using this brings its Cornered Multiattack limit down to 6 instead of 8.
Predict. The Arachnid makes a Wisdom (Perception) check against an opponent's passive Stealth (10 + Stealth modifier) (Unless, of course, the opponent is actively using Stealth). If it succeeds, it locks one eye on an enemy, never letting it leave its sight. While locked on, the dragon can use its reaction against that creature without spending a reaction. It can do this with up to seven creatures at once, or as many as it has eyes left minus one, but must make the perception checks one at a time each costing a legendary action.
Description
The Bladed Soul Arachnid is the best example of a Soul Beast. A long time ago, a powerful mage who wished for immortality created it and trapped in an outer shell as a Void Dragon. Since then, someone killed the dragon, releasing the Arachnid, which immediately set out to kill the mage who created it. Any who get in its way, it considers an enemy as well.
The Arachnid is pure white, with a body as round as smooth as an eggshell and eight black eyes that move around its body as it likes. Its eight legs are highly unusual, manifesting as a series of scissor blades.
