I understand there is some sort of scaling mechanism for resists related to multiple items providing resists. I don't fully understand the formula but I understand the intention. I believe this is bugged for characters with negative resists from the start of the game.
To test I bought the following 6 items on Infernus, McGinnis, and Pocket: Healing Booster, Restorative Locket, Mystic Vulnerability, Cold Front, Pristine Emblem, and Improved Spirit Armor.
You can see in the provided pictures, Infernus has 65% spirit resist. With the same items McGinnis has 73% spirit resist. This shows that her starting spirit resist is taken into account when buying more items, it is not a flat 25%, but instead scaled like items. Pocket has 50% spirit resist, which is a flat 15% lower than standard. It seems the formula was told to make pocket's spirit resist an exception, but I believe the correct calculation should be based on current spirit resist.
The way I believe it should work is that pocket should be less than 15% spirit resist behind infernus with the same items, because with the current system, pocket's spirit resist from items quickly diminishes at low spirit resist values.
