[sblock=OOC/Flanking/DR]In PF, pretty much the only things immune to flanking are those that have all-around sight or those that have no "front/back/sides" (such as oozes, slimes, cubes, etc). Also creatures with Improved Uncanny Dodge, though theirs is limited - they cannot be flanked unless the flanking person/whatever also has Improved Uncanny Dodge and is 4 levels higher than they are.
In case you want to retro, Manny/Relós' total damage (including the AoOs listed below) after DR would be 25.[/sblock]
As the golem struggles to rise, Manny and Relós take advantage of it's distraction to get in a couple of extra attacks. Manny's spear thrust pricks the thing's flank, while Relós' teeth continue to worry at the wound on it's calf, tearing it open further and injecting even more acid.
