It's possible that archery damage is reduced to 80% (or even lower) in PvP on this server.

I don't currently have the means to confirm this ingame myself, but when looking at the stock eqemu source I noticed the following in attack.cpp:

if(attack_skill == SkillArchery)
  PvPMitigation = 80;

It seems archery damage was initially reduced to 66% dmg in PvP during the LoY expansion, then increased to 80% during GoD.

Archery damage has been increased to 80% of its base damage in PvP, up from 66%.

At any rate, it should be full dmg during p99's era.
