well we know the triglav and sudaruskas charge attacks suck balls (and there damage is so bad compared to all other 5*s). What if..... they just made the charge attack different O.o there is currently way to much risk and low reward in there current charge attacks so lets start fantasizing a new attack

Sudaruska (the earthshaker)

Triglav (The glacier = moutain in your face)

I think that since both these swords give off the illusion of a larger range that there charge attack can be... A really large swing?
Basically this is what im thinkin. you take a slight step forward (like a brandish charge) but then you swing ur sword in a range that covers 180 degrees BUT 3 square radius. And because of the sheer brutality of these swords (or at least there decriptions like to lead us to beleive) after the slash there is a sort of shockwave/sonic boom kinda thing that hits 2 more times following the enemie (if its sudaruska its like a sandstorm/rockslike, if its triglav its snowstorm / hail).

i dont know if yall can imagine wut im sayin, but i think instead of coming up with ways to fix the charge attacks they might just need a whole new one since its currently impractical.

so summary. For both swords a charge attack that is .. small step forward, BIG SWING, sonic boom/wave doing status effect and extra damage (since these swords are the only 5* swords whos charge attack doesnt do multiple hits.

~also please fix there damages its so BAD as it is now :(
