Objective fights are won or lost before the objective even spawns. Here's the setup:

Tyrant (spawns at 5:00):
• At 4:30, reset and buy. You want full HP and your item spike for the fight.
• At 4:45, start pathing toward the Tyrant pit. Not toward your lane — toward the objective.
• At 4:50, ward the enemy jungle entrance near the Tyrant pit. You need to know if they're coming.
• At 5:00, if you have vision control and a numbers advantage, start the Tyrant. If not, wait.

Overlord (spawns at 10:00):
• Same setup, but the stakes are higher. Overlord wins games. Don't start it unless you're sure you can secure it.
• If the enemy team is alive and their jungler has Smite, don't start Overlord. Fight them first, then take Overlord.
