Interesting weapons but bad stats/slots?

[The Legendary Joe]

Grimtooth Dagger has the highest atk out of all the available daggers in game, and a flee boost on top of that, at the cost of halved defenses while using it. Cards and elements tend to outperform it though.

Moonlight dagger's +3 sp on attack is incredibly nice effect, but the dagger's low atk really keeps it from truely shining. I regularly use it on GC pally (with tormenting spirit) to recoop some of the SP used. It's a level 4 weapon so the refines do a lot for it. I could see it being better if it had more Attack power, or if it added some matk or something. With more attack, could make use of the Attack speed boost that Blue Beret gives it too.

Brocca- The original 1-hand spear with defense ignoring properties. Shafted by one little script that only applies def ignore to non-bosses. You want to hunt amistrs? tough luck, their boss flagged so they keep their defense, though it still boosts damage to neutral stuffs.

Brionac- Holy prop 2-h spear Autocasts soul strike. kinda weak in use.

Spear of Longinus for dark prop, has bonuses against demihumans, and angels, though 10% boosts are kinda low for current meta.

What was the original Double dagger combo? Desert Twilight [2] and Sandstorm [4]? I don't think I've really seen these. the chance at having aspd buffed to cap seems like it'd be fun with the sapha set, but not sure what the activation rate is, or how viable those daggers are.
