海龜盔甲 is a 困難模式 盔甲 set made up of the 海龜頭盔, 海龜鎧甲, and 海龜護腿. A full set grants a vastly amplified 荊棘 effect, which reflects full damage from melee attacks onto the attacking 敵怪. The full set of armor also provides 14% increased melee damage and 12% increased melee critical strike chance.
With no 時裝 items over it, a turtle shell appears on the player's back (much like the 吹葉機, 火焰噴射器, 精靈熔爐, and 高溫射線槍 backpacks).
Crafting this set requires a total of 54 葉綠錠s (324 葉綠礦) and 3 海龜殼s.
- The set's Thorns buff will stack with the 荊棘藥水.
- As of version 1.2.3, it is no longer possible to exploit this armor's Thorns effect to quickly defeat the 地牢守衛, as the Guardian's attack has been reduced to 1000 while his health remains at 9999.
- If one intends to craft both chest pieces of the 甲蟲盔甲, a total of 78 Chlorophyte Bars (468 Chlorophyte Ore) and 4 Turtle Shells are required to craft the whole Beetle armor set.
- The passive Thorns effect can be very convenient as many enemies — especially weak ones — will deal more damage to themselves than to you, effectively killing themselves. This, when combined with a Shield for 擊退 immunity, sometimes allows the player to completely ignore enemies.
- Combine with other tanking items like the 聖騎士護盾 for reducing damage to your friends, 冰凍海龜殼 for extra defense in low health, and 十字章護盾 which grants you immunity to most 減益s.
- You can combine the chest piece with the 葉綠面具 and 神聖護脛 for increased damage perks, but at the cost of losing the Thorns effect and some defense. The 神聖面具 is also a straight upgrade from the Turtle Helmet, and is more easily available than the Chlorophyte Mask. Equipping it on a set of Turtle Armor trades away the Thorns effect to gain an extra 4% damage, 10% critical strike chance, 10% speed, and 3 defense.
- 1.2.1：Updated female sprite.
- 18.104.22.168：The defense of Turtle Armor has been lowered from 71 to 65.
