The 蠕虫围巾 is an 专家模式 配饰 that reduces incoming damage by 17%. The Worm Scarf is always obtained from the 世界吞噬怪' 宝藏袋.
This damage reduction from this item is calculated after defense is applied:
Damage_taken = ( Raw_damage - (Defense * (.5 or .75 for normal or expert mode)) ) * (1 - .17)
- Percent damage reduction on accessories/potions apply first then damage reduction on set bonuses are applied (甲虫盔甲, 耀斑盔甲).
- As the game progresses, enemies will start hitting well into the 300-400 damage range. The Worm Scarf thus becomes valuable in reducing damage and making blows tolerable.
- Since the Worm Scarf can be taken into non-expert worlds, it is often a good idea to level a character up to near or post-Hardmode gear, create an Expert world, and easily defeat the Eater of Worlds for its Worm Scarf, which remains useful even at endgame.
- 甲虫盔甲 at its 45% state, 蠕虫围巾 (17%) and 耐力药水 (10%) will reduce damage by almost 60%.
(100%-45%) * (100%-(17%+10%)) = 40.15% damage taken = 59.85% damage reduction
- 冰冻海龟壳 (25%) will further increase it to almost 74%.
(100%-45%) * (100%-(25%+17%+10%)) = 26.4% damage taken = 73.6% damage reduction
