From the publisher's website:
The alchemists at Creation's Edge Games have been working overtime. Here's their latest batch. A baker's two-dozen(?) of tasty potions sure to please... and displease your enemies.
Buck-A-Batch: Magic Potions for 4th Edition Dungeons & Dragons features 25 unique new magic potions.
The items are presented in two formats for your convenience: Standard item template and a card format for cutting out and handing to your players.
This is not a translation of a 3rd edition product rather a completely new product for 4th edition rules.
