I just timed mining the bane ores and doing the spell and here is what I got. (Full Golden Mining/Dragon Pickaxe) No juju potion: You gained 13,922 mining exp in 35mins 36secs. That's 23,462 exp/h. With juju potion: You gained 7,560 mining exp in 17mins 12secs. That's 26,362 exp/h. Doing Tune Bane Ore: You gained 21,060 magic exp in 1min 11secs. That's 1,058,740 exp/h. -- Before you say anything, yes I only did a 1 minute timing for using the spell. It was 1 minute because you use the ores extremely quickly. Judging from that timing you'd need 11,494 Bane Ore to do a full hour of this spell. If we break that down some more: A Bane Ore mined with full golden = 93 exp 26362 mining xp an hour = 26362/93 = 283 ores an hour. 11494/283 = 40.6 It takes around 40 hours to mine the necessary ore to do a full hour of this spell. 1m/40 = 25 If you take into account mining times, the overall xp/h of the Tune Bane Ore spell is roughly 25k Mage xp/h. (I did this earlier and just copy pasted my thread from another board for here, I thought this would be relevant to the interests of the people in this thread)
