At this point, landslide is just too reliable. You can start running it by level 15, and it morphs into one of the more powerful endgame builds (Subterranean Creeper). It’s also shockingly easy to gear into. The terramote/creeper interaction gives you access to assured crits, and higher damage than you should realistically have at low level. Which is a shame since landslide is an incredibly boring playstyle.
Pulv/CocaineBear is also pretty easy to get into, and will perform decent even before you get the uniques. I dropped landslide for Pulv for leveling, but pulv does have a weakness in having awful single target.
