An alchemer that deals pierce dmg would be a nice addition.
(I know some ppls would think/say "The bullet bounces but it deals pierce dmg?" like on the similar threads).
Well if P6 really matters, then it should work different than the other alchemers,

We all know that when the freeze thaws/breaks naturally, the target would take like 180 dmg on T3, so I think breaking/thawing the freeze with hits should also deal dmg, but only minor(like 20-40 dmg on T3).
A pierce alchemer is iffy to me because of the slower bullet making enemies dodge and ricochets causing havoc with pierce weak enemies more often than not.
It's also important to realize that the game is actually in a better place the more limited weapons are in terms of damage types. Blasters being in every flavor definitely hurts the "make a variety of weapons" thing, and alchemers being "elemental in various statuses" with a single shadow variant does make them much more balanced against each other. A piercing alchemer would be less useful in use while also opening the door for people to "only use alchemers in every damage type" and thus reducing weapon variety.
