879. Cheers!
I'm also feeling pleased with my progress in Agrarian Skies 2, as I've got a resonant jetpack, and have gotten a number of useful crops including diamond, gold and redstone. I've even set up a little system for breeding animals (which are rather hostile in AS2!), moving the babies until they're adults and then moving those to a killbox for making pink slime. Next plan I think will be gathering more animals for that purpose.
One thing that's bothering me is that I have a cursed earth mob farm where the mobs are dropping onto diamond spikes... but the diamond spikes aren't killing them! They're getting down to half a heart and not dying. Which is damned annoying given how expensive those were.
