Combat sequence

Layered on top of the module's own combat AI, which still picks targets and positioning. The fight below moves through real hit-point-gated phases; every save DC and attack bonus computes from the stat block above at runtime.

I

Spellblade Cadence

Above 66% hp

He quickens a spell into his blade one round and lets it fly the next - Shock, then Chill, then a self-Haste - discharging what he banked while a fresh charge is already forming.

II

Runeblade

Crossing 66% hp, permanent

Every discharge from here on leaves a rune burned into the steel, a stacking mark that never fades for the rest of the fight.

III

Dragon Knight

Once, below 33% hp

His granted Epic Spell tears open the air behind him and something answers the summons for eight long rounds.

Why these numbers

CR 20 is set against Aventhine Hold - Level 2's own real ambient ceiling, not auto-computed from level alone - a genuine Fighter 4 / Wizard 6 / Eldritch_Knight 10 build at 20 total levels.

Hit points (175) follow this project's own average-hit-dice convention, and every save/attack bonus derives from the ability scores above at runtime - nothing here is hardcoded past the phase gates themselves.

How it's wired

Boss-flagged (bypasses the drop-rate roll, two loot-generation passes) and gated to a single spawn - only one Sir Aldous Cray is ever up in Aventhine Hold - Level 2 at a time.
