3rd edition's tatianna in classic combat variant

By septimus2, in DungeonQuest Revised Edition

I have 3rd edition and tatianna's ability is : ...reveal the top 5 cards on the combat deck and add any cards with a ranged attack type to your opponent's damage stack...
I use the classic combat variant (Quick shot,Slash,Bolt of agony) and tatianna's ability is unchanged, can someone tell me how tatianna's ability is used in classic combat variant since there are no damage stacks?

anyone?
