Ohmwrecker has a 100% win rate this season.

Yup, you read that title right, Ohmwrecker has a 100% win rate so far in Season 4. It has been picked up in two professional games, in the same week.

The first purchase of Ohmwrecker came out in Korea during the OGN Champions Spring qualifiers in the SKT T1 S vs Midas FIO match. The second barely over a day later in the European LCS during the Gambit vs ROCCAT game. There is some argument that it's a troll pick as SKT never used the item in their game, and Roccat were against Gambit's substitute squad, but I think the Roccat game shows it's potential viability.

Since the recipe change in 3.14 that dropped the price of Ohmwrecker by about 800g the item has been gold efficient on stats alone. It remains a mostly unused item though, and not for no reason. Items like the Talisman of Ascension, Sight Stone, and often Mikael's Crucible take priority for a support to aid in team fights. Ohmwrecker's turret disabling active is useless outside of tower sieging and while the AP and HP are nice they simply don't stack up to the benefits of the other aforementioned item's actives.

Ohmwrecker is definitely not useless though, and Roccat gave a perfect example of the situational viability of the item. When Roccat buy Ohmwrecker they're ahead and looking to siege on Gambit's inhibitor turrets, but they only have Ziggs and Lucian for ranged damage and Gambit has an incredible amount of wave clear. This is where Ohmwrecker shines, allowing Roccat to keep their siege champions under the turret longer in the face of heavy wave clear. It also comes in handy in more than one dive for them, disabling the turret long enough to win the fight without taking heavy casualties.

It's unlikely Ohmwrecker will ever be as popular a pick as the Talisman of Ascension, but in a season where games often turn during the inhibitor turret siege there's a niche for Ohmwrecker to fill. It's possible we wont see much more of it, but then again SKT and Roccat may have planted just enough of a seed for pro teams to value Ohmrecker's niche usage.
