The Kumo is a very aggressive creature that will lunge at its enemies without a second thought. It will use the sharp tip of its legs to stab its prey, or will attempt to bite. If one of its legs is ruptured from its body (by fire or other means), it will instantly regrow a new one. The Kumo is extremely strong and can break open a vault door strengthened by Unicorn horn, the strongest alloy known to the magical community. Although the Kumo has an intimidating size, it can be quite agile. It uses the force of all of its eight legs to leap into the air without difficulty.
