This Talent is based on Priam's soul. His body and mind can be destroyed, it doesn't matter.
Its cooldown is 86 400 seconds, or 24 hours. What matters is the passage of time for Priam's soul. Changing worlds can therefore be an interesting way of getting it to reset faster.
Please note: this cooldown is based on midnight (the earth time of Priam's first death at the end of the Tutorial). So, if Priam dies at 23:20 and resurrects at 23:50 (he can delay his resurrection for a maximum of 30 minutes), [He Who Eludes Death] will be primed again at midnight. This midnight is now completely out of sync with travel between worlds, which is why I've included a timer at the end of each chapter. ℝἈ𝐍ỌʙЕs
