You form a mental link between yourself and your targets within range and line of sight, forming a collective. All members of the collective may communicate telepathically with each other as long as they are in range of you; they still need to speak or understand the spoken language.

A member leaves your collective when they become out of your range, when they are killed, or when they enter an antimagic area. As long as you maintain your collective, you can add new members to it up to your limit of targets as a standard action. The target must be within your line of sight in order to add them to your collective.
