Since the anniversary ended, I've been saving up chao drops on a couple mules and today just finished 100 kills of chao on them. Here's my drop data so far. Keep in mind that this isn't quite at server rate - if the first run gave me a card I kept it for the 2nd run, although that didn't happen very often 100 Chao Tusks (1 guaranteed per run) 180 250 NX card (1 guaranteed per run, 80% chance of 2nd card per run) 28 1k NX card (probably ~25% rate?) 8 5k NX card (probably ~5% rate, got really lucky at the start with 5k 3 days in a row) = 950 nx/chao average (or 1900 nx/day) 6 black crystal 1286 Power Elixir (going to be hard to profit PE off chao it seems, with only ~12/run dropping) 2577 Sunset Dew (~25/run, double PE rate) 48 Tomaha's Potion of Speed 5 Earring for Str 30% 3 Pet for HP 30% 7 Red Cravens Hope this helps anyone wondering about chao profit! And feel free to share your own data
