Glorious Armor+Weapon
100% Vanilla-Friendly!
(The description for this mod keeps getting deleted for some odd reason and I’m too lazy to type it back up in its entirety, so here, have a tl;dr version!)
This mod adds a new armor set that you can make. Its stats are equivalent to Impervium armor, and it comes in long sleeve and short sleeve versions. Make it at any version of the manipulator for Solarium and stuff.
(A very very big thanks to Sayter. I edited some of his sprites to make this.)
