I have been reading on UO official for more information on Slayer weapons and was wondering if anyone can confirm whether the information is relevant to UOEx:
1) When armed with a slayer weapon, opposing groups do double damage to the attacker (you).
2) Super Slayers do 2x dmg while Lesser Slayers do 3x dmg. The reason for more damage on lesser slayers is that they work on a smaller group.
3) You must equip a slayer spellbook in order to reap the benefits of the spellbook's magical properties like slayer, SDI, and stat bonuses.
4) In damage calculation, damage increase is an additive percentage that determines base damage while consecrate weapon, enemy of one, and slayer bonuses are damage multipliers that will multiply your base damage.
