ToME: the Tales of Maj'Eyal

So, I want to donate and get the Ashes of Urh'Rok, but the "To buy any DLC you first need to have bought the game, either here or on some other stores for its nominal price of 6€." line doesn't go well with me.
Do I have to spend 6 euro for the game and then donate 5 euro to get the coins for the DLC? Don't get me wrong - I'm not stingy, I'm just a university student

4 not 5 but yes, you need to purchase the base game to use a dlc, as with most other games
PS: if you donate 10 directly you'll have an excess of 4 which you can use to grab the dlc directly

Ah, well, I guess I'll postpone it for now Thanks darkgod! You're making an amazing game which I've grown to love and hate!!!
