I've posted about this before, but wanted to present the information in a better way. There is a bug with Wormgod Caress and Glaives where if you have any stacks of Wormgod, then Radiant and Frozen melee bonuses will not be included in damage calculations. It gets a bit complex because the behavior differs between Legendary Glaives and Winterbite. Here is a summary of the bonuses given to glaives, with the error conditions in red: https://imgur.com/a/Clzhvp0 Essentially, any stacks of Wormgod will ignore the 2.2x melee bonus against frozen targets. If you're using Winterbite, it will also ignore Radiant if the radiant source comes from the solar subclass.
