Runeweaver Seylon - AI-generated fantasy Monster

Runeweaver Seylon

Seylon was once an accomplished magical linguist who believed every spell could be perfected through grammar, structure, and repetition. During an experiment involving a primordial incantation, several words vanished from reality. The resulting spell became The Broken Incantation, a ritual that rewrites the relationship between distance, motion, and intent. Seylon survived, but portions of his identity were replaced by living runes.

Agonizing Blast. When Seylon deals damage with Eldritch Lance, he adds 4 force damage to the damage roll. This bonus is already included in Eldritch Lance's damage.
Repelling Blast. When Seylon hits a Large or smaller creature with Eldritch Lance, he can push the target up to 10 feet away from him. This movement does not provoke opportunity attacks.
Runic Spellcasting. Seylon's spells and magical attacks count as magical. He has advantage on saving throws against being charmed or frightened while within 30 feet of an active rune pillar.
Rune Binding. Seylon can maintain up to three Rune Binding marks at once. If he applies a fourth mark, the oldest mark ends immediately.
Chain Hex. When a creature fails a saving throw against one of Seylon's rune effects, Seylon can attach a spectral chain to it until the end of that creature's next turn. While chained, the creature cannot take reactions.
Unbroken Concentration. Seylon has advantage on Constitution saving throws made to maintain concentration on spells.
Multiattack. Seylon makes two Eldritch Lance attacks, or uses Rune Collapse if available.
Eldritch Lance. Ranged Spell Attack: to hit, range 120 feet, one target. Hit: 11 () force damage. If the target is Large or smaller, Seylon can push it up to 10 feet away.
Rune Collapse. Seylon targets one creature within 90 feet bearing a Rune Binding mark. The target must make a Intelligence saving throw. On a failure, the target takes 22 () psychic damage and is restrained by luminous script until the end of Seylon's next turn. On a success, it takes half damage and is not restrained. The rune then shatters.
Chain Hex. Seylon chooses a point he can see within 120 feet. Chains of black-violet script erupt in a 15-foot-radius sphere centered there. Each creature in the area must make a Dexterity saving throw. On a failure, a creature takes 14 () force damage, is pulled up to 10 feet toward the center, and has its speed reduced to 0 until the start of Seylon's next turn. On a success, it takes half damage and suffers no movement effect. Seylon can use this action only once per round.
Rune Binding. Seylon inscribes a binding sigil on one creature he can see within 90 feet. The target must succeed on a Charisma saving throw or become marked for 1 minute. While marked, the target cannot willingly teleport or become invisible, and the first time on each turn that it moves 10 feet or more, it takes 5 () psychic damage. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success. Seylon can maintain Rune Binding on up to three creatures at once.
Rewrite Position. When a creature Seylon can see within 60 feet is pushed, pulled, or teleported, Seylon alters the destination. The creature must succeed on a Charisma saving throw or be moved to an unoccupied space within 10 feet of its intended destination, chosen by Seylon. Seylon can use this reaction once per round.
