So the issue is basically, the moment you fill up your monster book, and you pick up more cards from the same mob, you gain an effect. Now I've had it happen that e.g. the Monster Effect would be +2 acc, while I'm using Sniper pills. The monster effect doesn't stack, but it replaces my pill. Now of course, it's a ridiculously cheap example (400meso). But it's just annoying having to pay attention on when ur pet loots the new card, and you'd have to reuse your training potion. Similar with gaining +2 or +3 speed from a mob card, when I'm using speedpills. Hope this could get a review! Thanks
