黑曜石盔甲 is an 盔甲 set that consists of the 黑曜石逃犯帽, 黑曜石风衣, and the 黑曜石裤.
Wearing the full set provides an 18% increase of Summon damage and +1 minion slot, in addition to a set bonus of 50% increased Whip speed and range and another 25% Summon damage increase, for a total of 43% damage increase. It grants a total of 15 defense.
Wearing the full set does not provide a set bonus. It grants a total of 13 defense.
- 黑曜石盔甲 is statistically identical to 金盔甲, without taking into account Gold armor's set bonus. Both can also be acquired before the player obtains a 死亡使者镐 or 梦魇镐, but acquiring the obsidian will require 炸药 or an alternate form of mining.
- As of Desktop version 1.4.1 it now requires fighting either 克苏鲁之脑 or 世界吞噬怪 to obtain 组织样本s or 暗影鳞片s. Defeating them is not strictly necessary as 组织样本s can be dropped by 飞眼怪s and 暗影鳞片s can be dropped by segments of the 世界吞噬怪, even if you die during the fight.
- Using 炸药 can allow the player to get obsidian before getting the Deathbringer or Nightmare Pickaxe. Should the player be able to find great amounts of obsidian early on and acquire enough cobwebs (from a Spider Cave for example), the task of obtaining this armor set can be generally easier than finding enough gold ore to make a Gold armor set.
- Despite being made from obsidian, this armor set grants no special protection against the On Fire! or Burning debuff, whereas other obsidian-related items do, like the Obsidian Skin Potion and Obsidian Skull.
- Despite being a Pre-Hardmode armor set, it gives the third most summon damage boost out of every summon set, bypassing Bee, Spider, Hallowed and even Tiki armor, only beaten by Spooky and Stardust armor.
- 黑曜石盔甲是 7 套不提供套装奖励的盔甲套装之一，其他的是勇士盔甲、忍者盔甲、渔夫盔甲、爱斯基摩盔甲、粉爱斯基摩盔甲和雨具盔甲。
- This set's unique set bonus to whip damage is possibly a reference to cowboys often being depicted with whips, as this armor is themed around a wild west outlaw.
