On each page above — a "Build" section, which says at what minute to grab the slot and in what order.

How to answer

If the opponent built this slot, these approaches reduce the effect:

  • Disjoint mechanic (Manta, Eul) — drops a targeted cast before it lands.
  • Magic resist (Pipe, Hood, Eternal Shroud) — reduces magic damage.
  • Beat it on timing — build it before the opponent, take the first-move advantage.
  • Lobby check — watch net worth, predict when the build completes.

Usage tips

  • Timing matters more than the item. Close the slot before minute 25 — after that the potential is lost.
  • Hotkey: a fast bind through the inventory. Automated via Item Auto-Use.
  • Recharge: account for it in the push phase — cooldown — seconds.
  • Build path: components first, then the recipe. Changing the order is not worth it — you lose the bonus of each fragment.

FAQ

How much does Octarine Core cost?

The full recipe — 4,900 gold. With Hand of Midas or Bottle by minute 5 the slot completes around minute 18–22 on core heroes.

When to buy?

Depends on the role. On a carry (Pos 1) — after the first core build. On a support (Pos 4/5) — right after Boots and Wand. Details — on the hero page.

Does it stack with similar gear?

Identical active slots (e.g. two Mantas) don't give a double effect. Different savers (Manta + BKB + Linken's) — are independent and work in turn.

Where is the current meta build?

On the hero page in /scripts/ — the "Build" section. We update it after each studio patch.
