it says 'learn by hitting foes with sonic balls' so what are sonic balls? i have been using jasmch for a while, now lvl 17, but the catnap skill is still 0/100 exp. I have been using ice horn if that makes any dif, as i havent got any decent dual horns.
Raykuza posted... I was having the same problem, only with Flame On. I'm gonna try switching back to regular horn.
flame on also requires twinhorns, but those attacks needs to be directed at structures (the steel door tactic won't work, sadly). You need to attack enemies' bases and strongholds you see in missions in order to level this up.
