Please make alternate lines to the Snarble Barb to let it evolve into a Pierce/Shadow sword (which it looks like it should be) and a Shocking Pierce/Elemental sword.
These are two types of weapons the game is sorely lacking. The only ones in it are the Antigua line, and they're guns.
Additionally, there are no Electric/Shock weapons at 5* other than the Voltech line, which is a gun, and having it paired with a swift attacking sword makes sense to me.
The sun shards line of bombs does piercing and elemental, so it's not just the silversix and argent peacemaker.
It makes no sense for the snarble barb to evolve into something that deals shock. It's a beastly weapon and beasts don't use electricity. Perhaps a future construct boss can have tokens redeemable for shock weapons.
