Bastionbreaker

Bastionbreaker is a 3,000 gold Lethality item in League of Legends for assassins and AD casters who convert kills into objectives: 55 Attack Damage, 18 Lethality and 15 Ability Haste in patch 26.22. Shaped Charge adds true damage to your abilities, and Sabotage turns a fresh takedown into bonus true damage on your next hit against a turret or epic monster.

How do Shaped Charge and Sabotage work?

Shaped Charge is the combat half. Ability damage against an enemy champion or an epic monster deals extra true damage on top, which ignores armor completely, so it stacks neatly with the Lethality that already cuts through armor on everything else you do.

Sabotage is the unusual part, and it’s why the item has the name it has. Take down a champion within 3 seconds of damaging them and you hold Sabotage for 25000 seconds. Your next attack on a turret or an epic monster during that window deals additional true damage over 3 seconds. In practice, think of a roaming mid laner who wins a skirmish at a side lane and walks straight to the tower: that’s the exact play the passive is written for.

Exact true damage numbers? They scale with your stats, so Riot’s data files leave them to the in-game tooltip, and your shop screen shows the current values.

Is Bastionbreaker gold efficient?

Yes, and that’s before either passive counts. All three stats can be priced, and together they’re worth 3,215 gold against the 3,000 gold cost, a gold efficiency of 107%.

Here’s the split, using basic items from the same patch: 55 Attack Damage at 35 gold a point makes 1,925 gold, 18 Lethality at 30 gold a point makes 540, and 15 Ability Haste at 50 gold a point makes 750. So you’re getting a 215 gold surplus on raw stats, and Shaped Charge plus Sabotage come free on top (well, free in gold terms; Sabotage only pays out if you actually get the takedown).

What goes into the build path?

Just two pieces: The Brutalizer (1,337 gold) and Serrated Dirk (1,000 gold), then 663 gold to combine. The Brutalizer already has all three of the finished item’s stats, which makes it the better first purchase for a champion who leans on spells. Serrated Dirk is cheaper and more Lethality-heavy per gold, the natural pickup when a back leaves you a bit short.

Nothing upgrades from it (once it’s bought, that slot stops asking for gold).

Has Bastionbreaker changed since launch?

Once. Riot’s data first lists it in patch 26.1, and the only recorded change came later in the year:

• Patch 26.15: cost 3,200 → 3,000 gold.

Put simply, a straight price cut with the stats untouched is a buff. That cut also widened the surplus on raw stats by the full amount of the discount (the gold efficiency table above shows the math line by line). The full item list lets you compare it with every other Lethality option in the current patch.

Who should buy it?

AD champions whose damage comes mostly from abilities: assassins who combo with spells, and AD casters who poke from range. Shaped Charge only triggers on ability damage, so the more of your kill pressure sits in your spells, the more true damage you get. Does your champion also roam? Then Sabotage turns each successful gank into turret damage, which is the cleanest way an assassin’s kills translate into map pressure.

Marksmen and auto-attack fighters gain less. To be fair, they still get excellent stats. The catch is that Shaped Charge sits idle in an attack-based kit, and the Lethality line suits squishy targets far more than tanks. If you’re still settling on a role, our rundown of LoL roles explains which positions roam and which stay in lane, and that alone tells you whether Bastionbreaker’s second passive will ever fire for you.
