KOTL is a fun little game which is similar to a 1vs1, except there's a few differences. Basically one persons signature will start as the 'King' and you'll be challenged by another persons signature. The aim of the game is for the King to defend his 'King of the Labs' title up against as many other challenges as possible until he is beaten.
No topaz was used on this signature, nor was it used on my whitebeard one.
I've used topaz once, a while ago, not even sure which one it was. Topaz is only meant to be used on certain occasions, otherwise it looks bad.
