Logging in from Combat Logger

Combat Loggers

When you disconnect from the server while in combat, a Combat Logger NPC will spawn in, in your place. Players can re-log in at any time in place of their logger.

Combat Loggers do take knockback
When a player logs back in when they have a Combat Logger alive, they will log in at the Combat Logger's last position.
Combat Loggers keep the alignment of the player on disconnect.

Neutral Combat Loggers

When you disconnect while aligned neutral, your combat logger will be aligned neutral.

When you log back in, you will still be neutral.
If your logger dies, it will die as if it were neutral.
