Tier 2 Treasure Chest
The Tier 2 Treasure Chest is a special chest found in the last room of the Mars Dungeons. It contains valuable loot like Name Tags, Horse Armors, Music Discs and specially schematics, which are found only in these chests.
The treasure chest cannot be mined with a pickaxe, pushed by a piston and is not obtainable by normal means unless by
It has a large version like the double chest from vanilla if two treasure chests are manually placed adjacent to each other. (In Galacticraft 2 the double version of this chest was drawn as two separate chests side-by-side due to a bug. This is fixed in Galacticraft 3.)
In Galacticraft 2, a treasure chest can be "violated" by exploding a TNT next to it: the chest itself will be destroyed although no loot will be dropped unless the respective boss was already killed. (In Galacticraft 3, TNT will not destroy treasure chests.)
