Ice Splitter Uses Over Octopus

Don't listen to JakeAndBake. You won't need to freeze anything until 9x, to be quite honest, unless you for some reason want to get closer to Newties. Nothing should have the power to ohko you except a Jr. Newtie. If you want to train on stuff like that, Fake Shot will be more efficient since it lasts longer and the only skills that you have to unstun monsters are Gaviota, which you could just not use, or restun when it hits, and Octopus, which either should be on a different platform than you, or pinning the same monster as you're Burst Firing. I recommend learning one Octopus next level and moving on to Aqua to kill Squids.
