How to win a Rot victory in Armello?

First, it's worth noting that the King gains Rot every night, i.e. every other turn.

Rot victories are the most unreliable victory in Armello. Sometimes even a setup designed for a Rot victory will need to abandon it and go for something else (usually prestige). Other times you will get lucky, end up with plenty of Rot, and go for a rot victory from there.

Suiciding into Banes is often a bad idea. It's an inefficient use of turns since you have to return to clan grounds and you lose prestige. There are exceptions- if you're going to die at dawn anyway or sometimes for getting that 5th point (and potentially the 6th in the same battle if you kill each other). Generally though, if your strategy involves killing yourself more than once to gain Rot, you should be going for another victory type.

If you want lots of rot, you want to be drawing as many cards, (ideally spells which have a far better chance of causing rot) as possible. This means having high wits, using every card you can, and burning the rest whether it helps you or not.

Heroes that are particularly suited for a Rot victory are:

• Fang. Starting with 1 rot (for a total of 3 with Spoil) makes it much easier to get Corrupted. His ability allows him to kill banes for more rot without taking any damage or kill the king without worrying about dying in the process.
• Sargon. High Wits, good Spirit, and you can see the top card of decks and take them if they give rot.
• Yordana. High spirit, decent wit, and an ability for cycling expensive spells so you can draw more.
• Twiss. High Wits and Spirit. You can also steal cards from other players (which often end up being rot cards they don't want).
