First time beating Scrapped Watchman became easy?

Recently started playing 'Lies of P'. Got skill checked by the Scrapped Watchmen boss. After many attempts and then checking online- I got the advice to lean into the parry mechanic. So I would parried my way through the first phase and then dodge and try to parry the last. Over and over again I kept getting the boss down to 3/4 health and then I would fail.
So I finally tried out the 'Summon Specter'. The Specter proceeded to blindly smack the Boss whilst I played as normal and the Scrapped Watchmen went down super fast. Are Summon Specters meant to make boss fights this easy? I went from dam this is hard too well that was easy.
