Say you have managed to poison the opponent with two different characters,
one with poison 2, min 1, and the other one with poison 2, min 3.
Then if the opponent is left with 5 hearts after the last round, which one of the
poison effects is evaluated first? If the min 1 goes first, then the opponent should
end up with 3 life (as the min 3 won't take effect), and otherwise all the way
down to 1.
Here's what I found out from experience.
1st turn: Hit with Nina (poison 2 min.1)
At the end of 1st turn: N/A
2nd turn: N/A
At the end of 2nd turn: poison for 2
3rd turn:Hit with Gheistling (poison 1 min.1)
At the end of 3rd turn: poison for 2
At the end of 4th turn: poison for 1
The last poison overrides the first poison at the end of next turn.
