Per the info:
Overwhelming Surge - Tempest Island
Adds 1096 Maximum Magicka
Adds 258 Spell Damage
When you deal damage with a Class ability, you surround yourself with a torrent that deals 1114 Shock Damage to enemies within 8 meters of you every 1 second for 6 seconds. 15% of the damage you deal this way is restored to you as Magicka. This effect can occur every 7 seconds.
So...say I have 5 bad dudes around me...that's 1114 * 5...is that reflected in the 15% magicka restored? Or just a flat 15% of 1114 regardless of how many enemies it's hitting? Thank you.
