Gameplay Constants (Hero)

What do I need to fix in the gameplay constants, to make it so that you have to pay "10gold per amount of times the hero has died" to resurrect the hero, in GUI ?

Or if that doesn't work, 10gold per level of the Hero?

I've never been able to grasp this.

You can make it with 10 gold per Level, but the 10 gold per dead, that you propably have to trigger.
My idea would be an upgrade, with 10 gold per research Level, but the propblem is, it's very limited.

Which fields need to be modified in order for 10gold/level to work?

Like I said, I'm completely clueless when it comes to revival costs.

Hero Revive Cost - Gold Constant Factor, its set at .40 (40%)

Revive = Altar
Awaken = Insta ressurect at tavern

Thanks.

But 40% of what?

40% of the gold it cost me to buy it?
