Ice Splitter Uses Over Octopus

Well you're not really answering my main question. Why would getting Ice Splitter first make gaining levels faster?

My issue is ... what am I freezing exactly? With the areas to train for 70/80 in the guide, I think I would be better off just using Invis Shot or Burst instead of freezing. And if i'm using those sort of offensive killing skills, wouldn't Octopus be better?

Also getting the most out of your octopus would also require strategy as you gotta know when to drop it! ;-)

It depends where you train/want to train. If you're going the hime build (which makes leveling harder in the beginning because there's really nothing better than newties in 8x/9x), ice splitter and burner are to be maxed after burst fire.

If you're going the newtie build, which makes training much faster earlier on (i kinda want to avoid saying this since it's not confirmed how fast himes are for a mobbing outlaw >_>), octo is MUCH better. Ice splitter further increases your %/h once you can take a hit from newties as you can freeze the first one and kill the second before the first spawns, but you'll be high 9x and have high level splitter by the time that happens.
