Thought the devs should know.. if you equip ring of deflection on a character, save the game, then reload the save file, the deflection raises by +5. Save file, reload again, goes up +5 again.
I only noticed this after Eder ended up with like a 300 deflection rating or something at level 3 and was basically invincible to most attacks.
Sadly I had to start the game over because of this since there doesn't seem any way to reverse it.
Make sure not to equip any +deflection rings unless you want an invincible character :/
