A Ninja without Throwing...

[Akujima]

"Throwing attacks" is actually a good idea.

Another is an improvement to Sange, such as having more higher level, readily available shuriken (why SE would make Fuma Shuriken only yield 3 per synth and stack to 12 is beyond me). And I'm not talking about 400 DPS Shuriken, I'm talking about 120~ DMG (since Lv75 Koga Shuriken are 88 DMG) that would make sense.

The tactic behind it, if you haven't thought of it yet, would be to pop Sange at the beginning of the fight, and throw for some initial high burst DMG. The improvement to Sange would be, not to have it make you lose shadows and replace that with higher enmity generation or allow it to hit critically for each of the 5 shots or something along those lines.

Switching Qirmiz tathlum with another ammo piece does not make you lose TP. As for Ungur Boomerang? Oh well, but I suppose most of us could live without that extra 8 evasion. So there, I came up with an idea. But it's not like SE couldn't have figured out something like that for themselves.
