Chempunk Chainsword Changes

Patch 26.6

buff

Chempunk has been the weakest and least popular of the grievous wounds options for a while now. The reality is often that the AD fighters that would rely on this as their source of Grievous Wounds are also just worse at applying it and keeping it applied to key targets. As such, we are giving it a small buff so it can match up better with its Grievous peers

General

  • Total cost reduced to 3000 gold from 3100 gold.
  • Combine cost reduced to 250 gold from 350 gold.

Patch 25.5

change

General

  • Bug Fix: Corrected a tooltip issue.

Patch 14.19

change

We think of Grievous Wounds items in two ways: the Epic and the Legendary. Epics are cheap and readily accessible. Legendaries are slot efficient when you reach the end-game, but aren't meant to be great on their own. Because Chainsword is the only fighter upgrade to Executioners, it needs to be placed where it's not too squishy for juggernauts and not too tanky for the lighter fighters who don't want Mortal Reminder (or can't buy it because of Black Cleaver). So we're placing it at the midpoint on durability, raising its price to be worth the slot, and overall lowering its efficiency.

General

  • New Recipe: Executioner's Calling + Giant's Belt + Caulfield's Warhammer + 350 gold = 3100 gold.
  • Old Recipe: Executioner's Calling + Ruby Crystal + Caulfield's Warhammer + 500 gold = 2800 gold.
  • Health increased to 450 from 250.
  • Attack damage reduced to 45 from 55.

Patch 12.14

nerf

With our changes in Patch 12.11, Chempunk Chainsword became an incredibly gold efficient item, even with its reduced Grievous Wounds effects. Instead of nerfing the item’s stats we’re opting to increase its cost to bring it more in line with other Legendary Fighter item options.
