You guys all are fast makers or what :roll: ? Here are the calculations, forumula originate by viewtopic.php?f=143&t=788110&start=0 (dragon bones have raised by 1k per bone since the thread was made, see GE for details): altar (40 trips) (bones)3.2*1000+(marrentil, last for 3 min per burn)0.360*40 = 3214.4k ecto (31 trips) (bones)3.2*280*1.44+(terrorbird)0.385*2= 1291.01k Ecto with terror bird fletch you 403*288= 116k exp To get 252k from ecto, you need 2.1 hours Cost of 252k from ecto = 1291.01*2.1= 2713.211k So, altar cost 3214.4-2713.21= 501.19k more than ecto for 252k exp. But, we know that ecto need an extra 1.1 hour to archieve the 252k exp from 1 hour of altar... SO, if and only if you make over 455.62k per hour, wasting time to find a guy with altar is a waste of time. perfectionist should add these in calculations as well: altar: (teletab)0.935*40+ (duel rings) 1.8*5 ecto: (duel rings) 1.8*4
