Usually, when units that give buffs in their BB/SBB/UBB saying "boost all parameters," it doesnt incllude HP.

HP buffs are kind of special, so "boost to hp by %" will be mentioned if they do give HP buffs, like darvamshel.

In leader skills tho, boost to parameters usually include hp, like Haile, Ark, Gazia, etc.
