Today I came here with some questions and results regarding L2Character.getAttackByList() I've been using that trying to come up with an alternate implementation for 230_TestOfSummoner and I think that's a (major?) L2J issue...In short, here are my results: 1) getAttackByList only adds L2PcInstances! Whenever a summon attacks the mob, neither the summon instance NOR its owner is added in the list! 2) Attack lists are NOT cleared when a mob dies. Once it respawns ALL INFO in the attack list is the same as the last time the mob had spawned.

I'll stick around for a little while. BTW, I ran these experiments last night, after getting the latest L2J and DP from svn fulimnus, you think it could be a little part of performance problem ? If there is many PCs killing the same mob during day, it's storing list of all of them yeap...I really don't think it's good. and mutlipling it wit lot of mobs give quite big number Also, if I'm not mistaken, attackby list is used for rewards (not sure about that, I'll
