What HP is needed to survive Castellan's attacks (For mages+ others)?

After taking a while to get to Castellan in Ninja Castle, I finally reached him, hit him once and then he attacks me... I die lol. My character (FP mage) has 2.5k HP and 13.5k MP and MG of course. Would I need to have 13k HP or something in order to survive this boss's attack, or would HB/Decent HB suffice? What about other classes? Are high HP warriors the only ones who can survive there atm? Thanks for the answers

If you're not going to touch the boss, you would need 14.7k for second body, which translates to 2940 HP and 11760 MP.

I guess I'm kinda close then. I'd need like 400HP more, which I can easily obtain. But what about the first body? Thanks for the answers xD

1st Body requires less then 2nd but still over 14k (Or 2800HP/ 11200MP) . My sair had 14.3k when I attempted; I survived 1st body just fine, but 2nd killed me.

Thank you.

Just curious, but... After BB, if they don't change the damage rates on him... How much damage is to be expected?

Less than 1k. Attack and defense values HAVE to be changed.
