Upgrading supplementary skills.

What about non stat boost skills? Would it boost Electric nets hit% or anything like that?

*edit*

Looks like you cant buff stats effect skills. I have a Scythe I havent bothered to trick out and Ultrasonic cant be upgraded.

Electroe has double double doesn't it? That may be good with sword dance (which he learns naturally anyway) and then upgrade it. Might wanna have a taunt monster to absorb some attacks though. He may not have any matk moves but a S electroe may be useful against certain level with that combo if you can't afford the legendaries and don't have gryphon.

This strategy is what I use and what I was describing when we were discussing/arguing in the Suggestions Thread. It does deal BIG damage if I can make it to 3 sword dances. OHKO is possible with just Electric Ball + the Speed Boost.

I'd think throwing an upgraded Molten Core on a Ghost or Ice monster or Meditate on a Psychic monster if you can't afford a PoD might be a good idea. Though I'm hard pressed to consider this a good idea for ladder, I suspect it will only be valuable in Vet or Expert modes when you can't one shot monsters or maaaaaybe in PvP when fighting a monster younare strong against and can afford to take a hit or as a buffer against someone you know is leading with weather or PoD.

Its effective in PvP. though I still think that the cost of upgrading it depends on the Rarity of the monster it is equipped to. much like the same as when fusing Rune gems.
