Let me first say I was just checking the patch against a 1.32 savegame, so it might not affect new saves.  The Battlefields trainer let me learn Alchemy 4, and since I have some holy water I thought I'd make a permanent potion.  However I can keep making them, almost indefinitely.  The holy water is never used up, just the plants as normal, and since I have so many of them I quickly bumped Vitality/Mana/Stamina to 4000 each and the primary stats to 100+ each.  Obviously if it should work like that then it takes great willpower to not abuse this.
