You must possess a Resurrect Orb in your Chantra bag to use this feature.
Simply check the appropriate box and the bot will use your orbs to resurrect your character if it dies.
SAFETY TIP: Enable the Auto-Teleport option in CyanoBot and set its timing so that your character is teleported before its weapon is completely damaged! Otherwise, your character will be unable to fight and will keep dying, thus the resurrection will consume all of your Orbs!
