Crawler wiki

A Chaos animal-like melee unit. Weak, cheap, and strong in numbers.

They are weaker than the Swordwrath of the Order

An advantage is given when the ability "pack mentality" and "predatory edge" is purchased, the first allows more attack damage if more Crawlers are in your army, the second grants Crawlers a huge movement speed boost

Crawlers are good for scouting and taking out the squishier targets, their similar to the Shadowrath, except less powerful, but with a pack of more than 10 Crawlers, you can easily assasinate a Magikill, Meric, Archidons, and in some extreme cases, even Giants. never underestimate the power of a huge pack of crawlers.
