Make the sleeper have random loot. And for each game day he is awake make him a little bit more kill-able. Maybe a slowly ticking debuff to hp/attack or something. The last couple of game days he is up will be the only time he will susceptible to attack because of the slow debuff. So you basically get one shot to kill him before despawn if you can time it right. Then maybe 1 month or so respawn timer.
He prolly still wouldn't be killed, but it would be awesome to have something unknown in the game. Only the devs would know exactly whats on the loot table.
