I think you have to let your main attacker die and stay in map and party, while your leecher kills it. Correct me if im wrong
The attacker character would need to suicide to the eye. This prevents the attacker from getting EXP and also gives a large portion of the EXP to the remaining party members. Do not leave the party on any character. You can then Resurrect the attacker and continue with the 2nd Eye.
