1Hit Magician Skele Partying

I'm not sure, but my buddy says it's fasterer exp if you train wwith another Bishop.
But it's 2 bishops and 1 Arch Mage, am I right?

So it'll probably be slower.
If it's not that find yourself a partner, partner.

I know its faster to train with a bishop that attacks but on the other hand I am leveling my own bishop too if I go with my arch mage + my own bishop. Also, I'm looking for exp rate of a ARCH MAGE + BISHOP, not arch mage + bishop + leeching bishop nor a three person party (honestly the skele map is only big enough for 2 at most when you 1 hit everything).
