Wreathed in Void. Dryrch's Armor Class cannot be altered by any means.
Forgotten Instincts. Dryrch has two reactions and two bonus actions to use per round.
Foreseen Weakness. Dryrch crits on a 17, 18, 19, and 20. These crits bypass crit immunity.
Crimson Sacrifice. Dryrch may sacrifice 30 HP to gain another action. This can only be done up to twice per turn.
Drain Life. For every attack Dryrch hits, he regains 5 hit points.
Multiattack. Dryrch makes two melee or ranged attacks.
Armor Splitter. Melee Weapon Attack: +17 to hit, reach 5 ft., 1 target. Hit: 20 (3d8 + 17) magical piercing damage. When a creature is hit by this attack, they must make a DC 25 Dexterity saving throw or their Armor Class decreases by 5 until the end of Dryrch's next turn. This effect can stack.
Drachenveil. Melee Weapon Attack: +7 to hit, reach 10 ft., 1 target. Hit: 26 (6d6 + 17) magical slashing damage. When a creature is hit by this attack, they must make a DC 25 Constitution saving throw or become blinded until the end of Dryrch's next turn.
Denial. Ranged Weapon Attack: +17 to hit, range 500/3000 ft., 1 target. Hit: 20 (4d6 + 17) force damage. When a creature is hit by this attack, they must make a DC 25 Strength saving throw or have disadvantage on all saving throws until the end of Dryrch's next turn.
Hush. Ranged Weapon Attack: +17 to hit, range 120 ft., 1 target. Hit: 8 (2d4 + 8) fire damage. When a creature is hit by this attack, if it is concentrating on a spell or an effect, it needs to make a Constitution saving throw of DC 25 or lose concentration. Additionally, that creature is silenced until the end of Dryrch's next turn if it fails the saving throw.
Unseen Movement. Dryrch moves up to half his speed without taking opportunity attacks.
Within Shadows. Dryrch expends 60 ft. of movement to teleport up to 300 ft. to a point within view.
Spellsplitter. Dryrch may choose to roll a Dexterity saving throw when he is targeted by a spell or within a spell's area of effect. The DC is equal to 12 + the spell's level. If Dryrch succeeds on this saving throw, the spell is destroyed. If Dryrch fails on this saving throw, the spell goes through as intended.
Tenebrous Parry. When Dryrch is hit by a melee attack, he may choose to make the attacker and himself roll a contesting Strength or Dexterity check based on the weapon typing of the attacker. Should Dryrch beat the contesting check, the attack instead misses. If Dryrch beats the check by 10 or more, the attack misses and he uses one of his own melee attacks against the attacker.
