Normal version
The Normal version of the Hider is one of the simplest: the Hider, when they use their ability, cannot be killed by actions targeted at them; however, if their target dies as a result of an active killing action (e.g. a factional kill or Vigilante shot), the Hider will also die.
Variations
A Weak Hider is the original form of the Hider. This modified role is the most common version of this role (to the extent that many people will just say "Hider" to mean the role that has been standardised as "Weak Hider". A Weak role will die upon targeting a scum player, in addition to the other aspects of their role.
