Spell shields can block both the placement of a bomb and it's detonation.
Time Bomb will cancel an enemy champions recall.
If a bomb is placed on a stealthed ally, it will not be visible to the enemy team.
A ticking bomb will draw turret aggro.
A ticking bomb does not grant an assist if the target dies before it explodes.
A bomb will detonate an enemy Zilean's bomb when placed on the same unit. This does not prevent the enemy's damage.
If a bomb carrier takes lethal damage and triggers a revive effect, such as Chrono Shift or Guardian Angel, the bomb is removed like all other debuffs.
A ticking bomb will still detonate even if the carrier becomes untargetable. The carrier will still take damage unless they are also invulnerable, through effects such as Frozen Tomb or Zhonya's Hourglass.
Various champions that have abilities that make them untargetable can prevent the damage from Time Bomb, such as Vladimir, Elise, Fizz, Lissandra, Shaco, Fiora, Zed, Master Yi, or Maokai.

Chrono Shift can target a single allied champion.
The rune will not activate if the holder is killed by the Nexus Obelisk.
