The Death Mark when it ends deals the damage of 1 auto attack+ %damage dealt during the ult effect. Therefore if ignite ticks damage, they take part of it again, that's why if you have BotRK and use it on your ult target it can lead to massive amounts of burst damage, same reason why if you need some survivability then Sunfire Cape can do wonders for both offense and defense.

It doesn't truly amplify damage, just makes you take some of it again, which is sort of the same thing.
