Did any of the vanilla classes have a projectile based flechette? What I mean to ask is, did the warrior have a throwing flechette? I know the cleric has the gas bombs (very effective for killing the midboss) and the wizard had plain old explosions. I would say something it could toss with a mid range AoE.
As a side note, the maultaurs piss me right the fuck off with their shields deflecting mah serpent rod. Only gets worse when they get the ranged attack.
The warrior chucks them like a grenade, yeah. For them I gave the defense-oriented skill path, the Defender, bigger blast radius and immunity to the explosion.
As for the question I asked ages ago, I eventually settled on making the cleric's flechette do an initial explosion on popping the gas effect, along with a nailbomb effect.
Speaking of which, the cleric's flechetee is also damn effective against those centaurs.
