I want to ask a question about PB!!!

I want to ask about

If our team has only 5 people and not godly.

Question 1:left statue ,how to avoid my HP and MP become 1??????

Question 2:right statue, if the BOSS use skill to me and i can recovery half my HP and how to avoid die?

thanks?

i mean if i have only 1 team and not goldy?

what is the best method to defeat pb?

Edit:

Question:How to avoid left status to drop my 1 HP and 1 MP ?

I think like this:the attack of 1 HP and 1 MP only have a limited scale. so ..such as mech can use his skill on the right side of the left statue,

and Question 2 of the right status,how to avoid my HP recovery ability become the half of my total?

and if my HP is low ,I think I want survive ,is it possible?
