Sometimes, a Vitality Score may be used for a group of units. 'Units Within Range' corresponds to the units within the range of the skill + 1, which allows for the unit to move a bit before casting its ability at maximum range. Vitality is simply the sum of the current HP + Shields of a unit. Usually for ability usage, 'Vitality' is a key factor that is taken into consideration. For units with multiple abilities, abilities at the top will be prioritized over abilities below them if they are off cooldown. This page lists out abilities available to enemy spellcasters and provides you with information on the conditions the AI uses to determine when and where to cast any ability.
