Steam

Steam is an online game seller/host/repository that vends games through the Steam client, created by VALVe (the makers of Half-Life, Counter-Strike, Portal, Day of Defeat, Team Fortress, Left 4 Dead, and Dota 2). On 8/29/2018 RoM became one of those games.
At launch, the following DLC's were available:
Package	Steam Wallet	In-Game Diamonds	Notes
 	Free 	Free 	7-Day Flying Rune Disk, 7-Day Blue Note Cavy pet, Gathering Speed, XP & TP Potions, Death Forgiveness
 	$24.99 	 	Costume, house, Cloud mount, Kitsune pet, Class expansion ticket
 	$59.99 	 	Permanent backpack expansion tickets, Dragon mount, Costume, Puss in Boots, Weapon skin
 	† 	 	XP and TP potions and charms
 	† 	 	Hammers, Drillers and Refining Gems
 	† 	 	Marking Ink, Transport Runes, Hammers, XP, TP and Death potions
 	† 	 	Marking Ink, Transport Runes
† In-Game Item Shop only. 60% off normal price!
Yes, Gameforge is aware that the in-game diamonds price is very high compared to the Steam price. The whole point is to encourage the use of Steam Wallet, and Gameforge bases their valuation of diamonds on the discounted price, not the normal pricing the way we do.
UPDATE: Later that day, the DLC on the RoM Steam page were disabled until some issues can be resolved. We think this means that the price difference between Steam and in-game Item Shop was not intended to be so large and they are fixing it. see this post by Celes.
UPDATE: The DLCs on Steam are now delivering to the servers as intended and have been re-activated.

Steam rewards players for spending money from their Steam Wallet on items in Runes of Magic. This money spent earns roughly one Card per $9 spent, and if you collect all of a Series you can then build the displayed Badge (which displays on your public account but has no game effects) and may earn a 3-card Booster Pack. You must login at least once per week to maintain your eligibility for Booster Packs. 
Booster Packs do not contain any new cards, they just contain 3 cards from the set you have already seen. A Booster Pack costs 750 Gems to create.

Each Badge created/Level attained adds items to your inventory. These items "can" be broken down into Gems, and Gems can then be used to build Booster Packs.
