Psionic Amplifier

Device created by Dwarven Psionic Mind Masters Zellix and Tubla.

Item Description
The Psionic Amplifier looks like a small megaphone covered in glowing pink runes. A swirling white green liquid seems to move on its own inside the barrel of the megaphone.

Item Abilities
If a creature attempts to use its mind mastery ability or another psionic ability by speaking through the megaphone the duration and power of the spell is increased.

Mind Mastery Boost
A creature who uses Mind mastery through the cone causes a creature who fails the save to become a Psion Thrall under the control of the item's user. A creature may repeat the save at the end of each of its turns as well as when it takes damage. In absence of commands from the controlling party the Psion does nothing.
