but the point is that it says 'truly' invincible and not just casually invincible

the truly points to the actual meaning of the word and not some mild interpretation from FUG's point of view

I also thought that only Zahard would be truly invincible and I honestly don't take this blog post as a 100% confirmation that the 10 Heads are also invincible, but at the very least I consider it likely.
