Gold slime set: with armor, helm, shield, and a sword.
Armor and helm stats: identical to royal jelly set but with fire and stun resists.
Sword is a gold node crusher that deals fire on the charge
Shield is a gold node wall
The gold on these items would be shiny like Mercurial mail, but gold.
Each item would be won individually, auto bound.
Slime gold sprite harness... Basically a regular elite pierce harness but shinier and causes a glorp sound when the sprite wearing it deals damage.
Coins aura.... An old suggestion but never a more fitting time
Gilded righteous light... A piercing stun pulsar gun
Shimmering sheen storm... A stagger storm bomb with twinkling aura resembling a stack of slime coins
The Golden Slime Armor would have to be incremented by Tier, so that in Tier 1, you get a 1* or 2* version of it, in Tier 2, you get a 3* version, and in Tier 3, you get the 5* version.
Here are some things I came up with:
Fortune Blade: A gold, sparkling Leviathan Blade. The slashing sound effects are different (making more of a shing noise) and the charge gives off a yellow color. Perhaps it could give Stun like the Celestial Saber, or just be a Leviathan reskin; I'd be down with both as long as the blade looked sick.
Gold Dapper Combo: Makes sense, because the Casino is run by Slimes.
Deadly Gold Bomb: Reskin of Deadly Splinter Bomb, except pure, shiny gold, and deals Stun (maybe the regular Deadly Splinter could be changed to do that in a future update). Not very useful as a weapon, but it makes sense, as Slimes deal Piercing; until the fabled Shard Buff, it's just a collectible.
All the ideas I have for now.
