Hello! I have been looking into the piercing armors specifically recently because of their underestimation of use in the clockworks. I have to see which piercing armor is better (Excluding Skolver and Justifier because I'm tired of it)
-Dragon Scale (Elemental, Piercing, Poison, Fire, Beast Damage Bonus)
-Mercurial (Normal, highest pierce, shock, MSI Med)
-Royal Jelly (Normal, highest pierce, stun, sleep which will be coming back soon)
-Ice Queen (Normal highest pierce (apparantly the wiki states it has a higher pierce defense than the two above, but ingame, it has actually the same stats) freeze, stun)
-Virulisk (Normal, pierce, poison, slime bonus medium)
-Silvermail (Shadow, Piercing, Poison, curse, undead medium)
Note how Skolvers are like iPhones; everyone has one because of the bonus features.
Vogs: Android.
Snarbolax: Blackberry.
