I encountered a bug with the Jewel Socketing system. I just received two Clear Amethyst Defense gems, and I tried to apply them to two gear pieces. Once I applied them and wore the gear, I was escalated to 127 storm resist. However, when I went into battle and was attacked with a storm spell, it did the same amount of damage it usually does without the gems.
Spell Damage: 200 Storm Damage My Resist: 127 Storm Resist(48 normal resist + 79 gem resist)
That should be immunity and it should take out 0 but it took out 102 damage, which is very close to the amount it would take out without gem resist.
