Even after playing GD for several hundreds of hours it is really annoying to track all the conversion on your char.
Why not give the player more informations about the amount of damage, which is conversed by a small hint in the character Panel 2.
This would be a third or maybe even fourth entry after giving the information about Damage and Damage Modifier. Something like “x% is converted from Physical”.
For example:
Fire Damage 2000 - 4000
Fire Modifier 200%
Converted from 45% from Physical, 3% from Aether
Converted into 46% to Cold
This way all players have an easy to understand ingame “tool” to see if the build they choose is working in case of conversion rules, which honestly are still to complicated (at least for new players)
