User blog comment:Sweetraindrops/Discoveries Regarding Limit Breaking/@comment-24843529-20141224011538

I (and probably many others) can confirm point 1 in unofficial discoveries is true. I tried it with my tenko. You get 1 skill up initially from the fusion and another skill up from the raise in level. My tenko was at level 70 when it fused it though so I'm not sure whether you need to level up the fusing daemon.
