The damage shown in the pictures above show the mistwalker having not much more than half the damage of the krom, but the wiki shows the damage should difference should be much less.

TBH, I don't really see the purpose of the krom currently. There's nothing outside of mistlands that needs anything more powerful than a BM sword. The mistwalker adds elemental damage to help deal with the ML mobs, which the krom lacks, so what is it intended to be used for?
