The Cyborc is a melee enemy type encountered in Chaos 2 and Chaos 5 difficulty. It has as much health as an Orc and deals a moderate amount of damage. They carry a large hammer they use to slam into the ground sending out an emp shockwave that disables Auras, Traps, and Nodes for a short time.
To deal with Cyborcs you will want to use Towers and Blockades since they will not be disabled. Cannons, Ramsters and Poison Dart Towers are particularly effective in these two Chaos tiers. A Tenacity Servo mod can shorten or immunize Defenses against this disable.
