Need to know the number of bones I can use on a gilded altar per hour using the "use 'x'" option. Thanks.

At last check, it was roughly 1600-1800 per hour with a war tort.

With a Terrorbird, it's 3 minutes to complete one run from bank to Yanille carrying 40 bones (so about 800 per hour). With a tort, you'll be carrying more per run, so maybe 4 minutes? But you'll be running less, so I can't say time-wise for tort. Try running an inventory and time it if you don't get any definite answers. Good luck!
