While it was said that Zahard "cannot be killed" (not invincibility), the 10 Great Warriors have only been said to be invincible. If you thought Zahard is "only" invincible until now, then the vocabulary recap should have helped. He is likely as invincible as the 10 Great Warriors, but he's also immortal (within the bounds of the Tower) as has been stated explicitly.

We can argue the subjective aspects of the "invincibility" of these characters, but that is still going to be discussion about invincibility, not whether or not the characters can be killed.
