Ants

After the protective barrier provided by the vest was completely destroyed, Emery could only depend on his [Jade Skin] spell to withstand the attacks of those crawling and flying creatures.

Fortunately, the crystal green layer of rocks that covered most of his body was strong enough to hold the creatures' jaws, preventing them from biting a piece of Emery's flesh off.

At first, Emery's strategy, or should he say 'thought', was to close up on the beast tamer and incapacitate him, before the creatures could break through his defenses. In short, Emery planned to subdue the commander.

Emery of course expected the process would have some alterations, as the things happening during the fight could change to anything. But he never expected that the matter would be so difficult.
