Prior to EG2013 I had an estimated 1490 energy and was FULL. (approaching tier 2) I used 1000 energy to ensorcell for a friend and was at an estimated 490 energy.

After EG2013 I did my necroweek and maxed my energy for the week and was at an estimated 1550 energy (enough for a Tier 2)

Was something funny at EG with necroenergy in the necropolis that allowed me to gain more than the normal T1 per week's energy? Did I complete a Tier 1 for my friend at less than the normal cost?
