There's still the issue of another wizard killing your target, perhaps even accidentally (e.g. paladin retaliation). Also, it wouldn't be that much fun if an early kill would immediately finish the game.
I do have an alternative proposal :
In the trading card game Vampire The Eternal Struggle (2 to 6 players), victory conditions work as follows :
- The person to your left is your prey, the person to your right is your predator.
- When a player is ousted, that person's predator gains 1 victory point, no matter who made the final kill.
- This player's new prey will be the former prey of the now dead player. (which means rule 1 still applies, if you consider the dead player to no longer be there)
- The game ends when only 1 player is left, that person gains an additional victory point for surviving.
- Whoever has the most victory points wins the game. (so not necessarily the last man standing)
I believe the same could easily be applied to a game of chaos reborn, without too much complications that you may have otherwise.
The only real difference I see, is that the game would end when the turn limit is reached. But you could give all surviving players a victory point (rule 4). One downside as well (if you may call it that), is that the game can end in a tie.
Under these conditions, you might even strategically kill a wizard that is not your prey. (because they are getting too strong, or because they are leading in victory points)
Let me know what you think Sam, just throwing out the idea. Don't mean to hijack your idea.
