Also changed behind the tooltip: effects, spellLevel (not shown in a tooltip line). See the full field diff below for both values side by side.

A value this tooltip would print is left out: the referenced number is not in the tables this build ships, so it is not stated rather than invented. Values that depend on your character (level, Spirit, Attack Power, spell power) are named in words instead of given a number.
