PSYCHIC LINK

By Dr Mike

Characters with this attribute are linked to others with the same attribute. Whenever one takes damage, the same damage is applied to all other Psychic Link characters in the level.

This one lends itself to some interesting uses:

A big tough 'body' character with a fragile controlling 'brain'. The brain can get hurt easily, taking down the body if they have equivalent hit points. This could make interesting play for heroes or an intersting mod level with an almost invulnerable memberof the link who cna only be harmed by targetting their linked ally.
Give this attribute to a hero in a mod and also to a villain. When the villain appears, the linked hero will have a hard time taking them down.
Give this to a character who clones themselves. They'll take damage whenever the clones do, leading to a vastly different set of tactics from the usual 'cannon fodder' approach. Definitely combine with the CLONE COMMANDS option to allow the controllable character to retreat their clones from danger.
