Sonic blade vs. Spiral Air for farming

Hi. I'm a lv65ish warrior, two-handed sword. About blade skills: thinking about farming, do you think is worth to level up Spiral Air to lv10 instead of my Sonic Blade lv10 i've got already. Counting that the former is 300MP every use, against 200MP of the last, and that 10 skill points is value...
Tx.

 

Sonic Blade allows you to hit multiple targets and deal double damage on consecutive use.
Spiral Air only hits 1 target and gives a short and minor crit damage buff.

Spiral Air makes a good save skill for combos, Sonic Blade is what you want for farming.

 

Tx Red_Fox, thought Spiral was a multiple targets too. Any better blade skill for farming multiple targets in higher levels?

 

Tempest is an aoe based skill as well. It is similar to storm in terms of animation. Deals more damage, but quicker animation compared to storm

 

And do you believe Tempest is worth spending 10 skill points against Sonic Blade for farming?

 

Yes but only for farming, and mob farming becomes outdated beyond lv120. Or odelons if they allow tempest...

No because tempest animation p!ss crazy slooooooowww. Meteor cant replace tempest as aoe but binding strike can (many forgotten bout this skill but afaik its no good too)

Tl:dr, get tempest at ur own risk, weigh the pros and cons. Unless u have no lv150, u shouldnt take tempest.

 

Tempest is a nice skill to get. It doesn't do as much damage as the tier 4 skills, but it is overall a nice skill since it does a good amount of damage, costs less mp than meteor, and causes magic proration.
