Great in theory, but let's face this : I have 1 oak guardian. let's not exaggerate. plus.. 1 fractal. 1x9, correct? that makes 9 oak guardian.
Well then I throw in.. 6 devourer. ^^
normally, devourer's unburied would all die with one RoF, correct? or even oty's; or a few other things.
so, 9 oak guardians = 9 extra hp, plus devourer's natural 2 hp, makes 11 hp just for one devourer. if we aim all in just one devourer, that makes.. well, over 80 hp. That if X is every oak guardian adds hp with the number they have in field.
IF they add only 1 hp, 2+9 =11
