I believe I got my first unique weapon as early as the "winter" floor, though it might have been the one before that and I just didn't notice. My collection includes
. Here's what I've gleaned from the special abilities of these weapons so far:
1)
deals one more hit than the average sword, so four total. The first three deal damage anywhere from x0 to x2 the listed damage, while the fourth sends out a big shockwave that deals one hit of the listed damage to any enemies inside its radius. No apparent invincibility or HP-stealing effects. The secondary attack charges up a
and fires it in the direction the arrow is pointing upon launch, however it can only deal one hit before disappearing and is subject to the same x0-to-x2 multiplier as the normal hits, so it's hardly useful.
2)
functions the same as other
, though once you start charging the primary attack it sends out a wave of stars that deals the listed damage to whatever it hits (I haven't kept track of whether it can hit multiple targets or just one). No apparent invincibility or HP-stealing effects.
3) See my previous post for this weapon's effects. I'll add that the secondary attack needs to hit a certain number of times before the "finisher" activates, though I still need to work that number out.
4)
functions the same as other dolls, though the primary attack is noticeably more focused and thus easier to get all parts of the attack to hit your target. No apparent invinciblity or HP-stealing effects.
5)
functions the same as other dolls, though both the primary and secondary attacks feature projectiles that bounce a few times after firing. The projectiles also have HP-stealing properties, though no invincibility is granted.
