So yeah, the double/triple random, are VERY powerful early on. Just DONT expand the options for a few times (as it increases what the randoms can hit)
You want accuracy at 60 or higher ASAP, with a good mix of aspd too.
Once you get that, static is the next big thing (this is MASSIVE later on, so get it early) Then try to get leech (and NEVER get heal ups, unless it comes with a max HP upgrade)
IGNORE BASE DMG ENTIRELY (static will VASTLY overpower it)
Blue flame, is also a joke.
