i know who thauma give like 800 of magic damage but its need a loot of money and 3 circle to get it and it counts like 3 buff
so E.L. give 500 and work like a normal elemental damage bonus. (not like blessing who give an amount of flat damage) it can be modifier by the skill atribute or some spells like quick cast or the atribute of archers who twice the damage to flying monsters with 2h bow (becos elemental atack works like magic and physical at the same time)
soo the most usefull suport could be a linker 2 crono3 enchanter. ? tis build works enhacing the power of the party dont care who clase they are
