The Anchor is an Object of Power boss found in the Clockwork Department. It's a large, clock-like entity that manipulates time and summons Hiss. The main mechanic of this fight is to throw the glowing clock weights at the Anchor when it opens its 'mouth' to attack. You'll need to time your throws carefully to hit its vulnerable core. Use Evade to dodge its time-distorting attacks and focus on clearing the Hiss it summons to prevent them from overwhelming you. Patience and precise timing are key.
