Burn from Within deals X damage to target creature or player. If a creature is dealt damage this way, it loses indestructible until end of turn. If that creature would die this turn, exile it instead.

You can target a creature that doesn’t have indestructible with Burn from Within. It will still be exiled if it would die this turn.

If Burn from Within doesn’t deal damage to the target creature (perhaps because that damage was prevented or X is 0), neither additional effect will apply. It won’t lose indestructible, and it won’t be exiled instead of dying that turn.

The damaged creature will be exiled if it would die for any reason that turn, not just if it dies due to damage from Burn from Within.
