Other then the difficulty with the sigil earlier, I'm really loving this mod-pack! Blood magic has slowly turned into one of my favorite mod's after Agrarian Skies, so it was nice to see a magic pack based on this mod and not all centered around Thaumcraft. In fact, Thaumcraft seems to be given little focus so far and I personally like that! I mean, I can only stand the Thaumcraft grind so much.
One person complained that there was too much grind in this pack and I personally have to disagree. I mean, of course it's grindy, it's Skyblock. That's what Skyblock is all about. But it's a different grind. It's not your typical sieve and gather cobble grind and I really like that.
I guess my only complaint was that the wait for ores in the beginning took a little too long, but then again, I didn't know the watering can worked on the bush's then. Overall, out of all the jam-packed pack's this is my favorite so far. Just because it focus's on one of my favorite mod's and the story hits a personal spot for me.
