Omni-tools

Omni-tools are multipurpose diagnostic and manufacturing tools as well as computers used for a variety of civilian and battlefield tasks, such as hacking, decryption, or repair. Higher-end omni-tools are equipped by Engineers, Sentinels, and Infiltrators to make use of their tech talents and powers. When activated, an omni-tool can appear over either of a person's forearms and/or hands, and occasionally both, as an orange hologram.
