I was digging through the CoreAbilities.xml and by extension the CoreSpells.xml and I came across two relatively minor errors/bugs which could be fixed fairly quickly and easily for the next patch.

Firstly, the spell Soulburning doesn't calc resist damage properly. The text says half damage on resist, but the math says 12 + (3*Shardstotal) for full damage, and 6 + (3*shardstotal) for resisted damage. This is, obviously, only half BASE damage. The correct math should be (12 + (3*Shardstotal))/2.

Secondly, the unit "trait" which is used in unit design for "stealthy" doesn't seem to have any actual game effect other than a text description. The Sovereign picked ability applies a global -100 to monster agression, but the unit trait has no modifier in it except for a text description.

Of course, there is the current 1.1 bug that the Heroic Sovereign trait is cost 0 in the default files, which is obviously an oversight.

There is also still the typo "<Text>If an enemy is particurly vulnerable or resistant to your attack you will see" in CoreFlavorText.xml

The next time I do an xml edit from scratch, I will keep track of my changes in a changelog format to submit as feedback for balance changes.
