Pack Mentality is one of the two researchable abilities for the Crawler, the main early game Chaos unit.
Description[]
Crawlers gain +1.2 attack damage for each Crawler in play, stacking up to 5 times (+6 attack damage).
Strategy[]
Preadatory Edge greatly enhances Crawlers' lethality and makes them able to dive in and execute low health units from the bonus damage, and to trade well with melee units; with maximum stacks, the Crawler's damage is more than doubled. It's a very useful ability to chase down and kill weaker units like Earth Elementals, Swordwrath, and Archidons, and frequently forces an Order or Elemental Player to fall back to protect their low hp units, but it would be hard for crawlers to kill against a more tanked Armored unit, like a Charrog, without heavy losses. This is why the Crawler's other upgrade, Predatory Edge, is a great asset and combination towards Crawlers. Usually Players would research both abilities at the same time.
