That's not going to work very well, because (as you pointed out) some players will intentionally drop link to avoid losing. Making it an automatic death is also pretty unfair, as the player may only lose their connection for a few seconds.

I would propose using that are . If the character doesn't act within their allocated turn time then they either do nothing, attempt to use a defensive or escape option, or they use some default option/s that the player has configured in advance - whichever approach you prefer.
