I've run into a situation where stacking buffs is giving fewer stats than expected.

With 4 Base Resistance and 31 Unscaled Resistance, installing Izabe will raise the Resistance to 45. Brighten and Sanctuary don't increase this.

Using Brighten and Sanctuary on their own only cause my Resistance to raise by +13, rather than +20, regardless of the casting order.

Similarly, using Astral Belt along with Sanctuary only gives +17 Defense.

Is there a cap, and if so, what goes against it? Food, Traits, Birth Sign, Buffs, LE Traits, Equipment, etc.
