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.
Whatever buff the nearest foe is carrying, she steals its shape and answers with her own version of it.
A vanish, a reappearance beside the weakest foe, and whatever she stole last comes with her.
A granted Epic Spell conjures a temporary ally that fights on for eight rounds.
CR 13 is set against The Outer Tunnels's own real ambient ceiling, not auto-computed from level alone - a genuine Rogue 5 / Wizard 4 / Arcane_Trickster 4 build at 13 total levels.
Hit points (57) 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.
Boss-flagged (bypasses the drop-rate roll, two loot-generation passes) and gated to a single spawn - only one Fennick Sly is ever up in The Outer Tunnels at a time.
