Soul Rebirth has a Passive component which will respawn the hero with 50% health at the location they died after 4 seconds; this effect has a cooldown of 180 seconds, which can be reduced with additional Cooldown Reduction.
When Soul Rebirth's passive effect triggers, an animation is shown of the hero rising from their body before finally respawning.
