[PokemonTrainer]

Hello...im new to this for editing maps on world editor.
I was just wondering...what are the triggers to revive heroes but with a timer because i can only find hero revive instantly.
exemple:A hero dies,(optional):a timer shows for the player for when the hero will revive,(wanted):timer (like 1 min time)

make a trigger like this
Event: A unit dies
Condition: Dieing unit Equal to (Hero)
Actions: Wait (time)
Revive dieing hero instantly
