I'm relatively new to Castle Story (level 18) I've recently bought some gems because I want to buy one of the gem animals. My question is should I buy the Alicorn, Manticore or one of the Dragons? I know this is a rather subjective question and I'll welcome any and all input. I'm mostly just trying to find which animal is going to give the best/most useful drops. Don't want to waste those gems! I appreciate any info you have to share.
