Depending on the available augments (assuming the Evolith system is involved), this will either be a really good mainhand weapon or cool-looking town gear. The delay is too high to make use of it without additional stats, but you never know...
This sword holds 3 evoliths the first two will essentially be attack+ during weaponskills and critical hits+ during weaponskills. Each of them have a strength of 8.
The third evolith is an open triangle of any element leaving you with many options however it only has a strength of five. This gives you the option of +BlueMagics accuracy, attack, MAB, and MACC in addition to a plethora of other magical enchantments albeit slightly less useful.
Will likely default to best mainhand weapon for BLU because of its 46 DMG, highest for a BLU weapon to date.
@Kalico: Wait until you see what stats are on it before dismissing... the fact that it has 2 more DMG than Perdu and 3 more than Koggel is pretty significant.
I just like it on the way it looks, nowadays you have better options, but this reminds me of a chunk of coral fashioned into a sword or something like that. This is definitely a head turner.
