Yea. Death occurs when Vitality drops and drops some more. Bad things reduce Vitality including, but not limited to, drowning, poisons, getting stabbed, getting slashed, getting punched, diseases, fire, things that hurt, things that stomp, and etcetera, etcetera, and etcetera. 

So no, unless you really intentionally want your chara to die, then you cannot plan your death. 

Thought the gifs I put there got that across at how HILARIOUS I thought that was. 

Planning your characters' deaths. Acting like you have a choice in the manner of when you get to die. How adorable X3

Someone has obviously never played table top before. You don't plan that shit. It just happens :3

(Like real life for instance)
