Call the concept "Opposed Skills" or something like that.
Effective Chivalry = Actual Chivalry - Actual Necromancy
Effective Necromancy = Actual Necromancy - Actual Chivalry
Effective Bushido = Actual Bushido - Actual Ninjitsu
Effective Ninjitsu = Actual Ninjitsu - Actual Bushido
Skip the Spirit Speak changes, skip the Vampiric Embrace changes, skip everything. You wanna have 100 Chiv and 40 Necro, smartypants? Now you're casting like you have 60 Chiv and 0 Necro.
Love the idea. Simple and effective solution that would effectively eliminate opposed skills on the same character.
I'd love to see the Chiv formula look like:
Effective Chiv = actual Chiv - (necromancy + poisoning/2 + actual stealth/2 + stealing/2 + snooping/2)
Chiv would be in major opposition to necro and minor opposition skills that are less the chivalrous such as stealth, snooping, stealing and poisoning.
Effective Stealth = Actual Stealth - (chiv/2 + bushido/2)
I am assuming actual skill = real skill or unmodified skill which would allow people to use items to make limited opposed skills work together.
People will find this harsh and make chiv useless. I'd argue chiv would only be useless if you plan to be a dp stealth death strike assassin necro Paladin.
When you look at that sentence which word does not belong
