Patch 16.14 changed Protoplasm Harness, so we measured it: the win rate of games with this item after the patch against the same games before it, in wins per 100 games. That is the figure above. Games before the patch beat games after it. The full report is further down this page and on the patch 16.14 page.

What players finish with Protoplasm Harness
Items that turned up in the same finished build, counted. Riot's data here ships no recipe list, so this is what players bought together, never a build path.

Dead Man's Plate 87 games with both · 6.0% 
Thornmail 82 games with both · 5.7% The share is how many of Protoplasm Harness's own 1,451 recorded games also finished that item, so it can never pass 100%. 7 more items appeared beside it in under 30 games each and are left out. Counted, not looked up: it is what players bought together, and it is not a recipe.
When Protoplasm Harness gets bought
Stamped at the moment of the buy, so how the game ended cannot move it.
- all recorded buys
- 21:28
- bought while ahead on gold
- 21:46
- bought while not ahead
- 20:26
333 recorded buys: 137 ahead on gold, 196 not ahead. Ahead means a lead of at least 1,000 gold at the buy. Bars run to 40:00 on the game clock; half of all buys fall between 13:55 and 25:23.
These are every recorded buy of Protoplasm Harness, not just the first one in a game, so the middle time sits later than the time you would first build it. The two rows underneath split the same buys by whether the buyer was ahead on gold when they bought.
What patch 16.14 changed
The one measurement here that a win rate cannot fake.
Protoplasm Harness
games after the patch against the same games before it
-1.5 wins per 100 games(range -2.9 to -0.1) 21,570 games Measured 7,011 games on the thinner side of the boundary, 10 days each way. Games before the patch beat games after it. The full report is on the patch 16.14 page.
How this page is counted
Short version here. Every number above says which of these it came from.
Games come from finished builds: each recorded player lands in exactly one finished item set, so the buyers chips add up without counting anybody twice. We keep the most common finished builds per champion and role, so the total is a lower bound. How items are counted.
Why there is no win rate on this page
A finished item set is read at the end of the game. A player who bought Protoplasm Harness and lost the game at twenty minutes never finished it, so they are not in these rows. Every player who is in them survived long enough to finish a 2,600 gold item. That makes the win rate of the pool high for reasons that have nothing to do with the item, and worse, we cannot say by how much.
Every other site prints that number anyway. We print the games, the timing at the buy, and the before-and-after comparison when there is one, and we say when we have nothing.
