Conadium

Conadium was a synthetic compound which was resilient to nadion beams. Conadium was a portmanteau of the Prefix Contra and the particle Nadion. Conadium was believed to be engineered to be ablative, absorbing and practically disregarding any effectivity (not entirely) of phasers.

Conadium in Polyhexabunadium made it highly resistant to a maximum setting phaser bank. Although if all of a ships phasers at maximum were to fire, it was possible it could begin damaging it.
