jinpu is a strange ws, it doesnt do pure wind, it does a combination of the two. note, its purely fueled by a str wsc, it's multihit, and the only elemental ws stackable with SATA.
i think this was taken under VV gales and stout arm, both the melee and magic temps in abyssea boost its spikes to ridiculous amounts... back on topic, it's still got a physical aspect to it, and i still wouldn't use it on a bird. i would use the one with a higher wsc and 33% atk bonus.
trolls need to go back under their bridges.
