Do you get negative resistence from a negative attunement?

I am arguing with guildmate about how resistance is calculated. It seems to me that if +100 attunement gives you +50 resistance, then a -100 attunement would provide -50 resistance.

 

Its a little more involved than that, but you've got the right idea.

When a negative spell is cast on a target, the effective attunement is calculated as,

effective attunement = attackers attunement - (defender's attunement / 2) - defender's resistance

For example,

if caster has 200 attunement, target has 100 attunement and 50 resist:

effective attunement = 200 - (100/2) - 50 = 100

if caster has 200 attunement, target has -100 attunement and 50 resist:

effective attunement = 200 - (-100/2) - 50 = 200

I hope this helps!

 

thanks, good info.

 

Here are some sensitivity tables, if they help:
