The Red-Nosed Reindeer - Sword Art Online Episode 3 Reaction

The revival item has to be used on the player within 10 seconds in order to prevent the Nerve Gear sending out the signal to fry the persons brain. After that, even if they technically revived the persons avatar, the real person would be dead.

Love episode 😁😇

Probably doesn't matter anymore but to clerify. The dungeon monsters were around level 30 the players were level 20 and Kirito being a higher level knew that none of them could beat the monsters. Kirito had no problem defeating all of the monsters because he was a higher level than them, if the monsters were Kirito's level he would of probably died too.
