I noticed some issues in the Essence Companion.
I'm playing a Warrior mage for near of 2 years now.
There are mistakes in few spell lists.
1/ The area of effect of Zephyr (first spell of Air Mastery), it says "target" but in the description of the spell, the only target seems to be the caster.
2/ Combat Illusion: Beacon is defined as seventeenth in the table, but the description is at thirteenth rank.
