Authentic Force
Authentic force is used in Grandis to penetrate the defense system of monsters in Grandis. Authentic Symbols are the only source of Authentic Force. Based on your Authentic Force and required Authentic Force, your damage is adjusted to between 5% to 125% of the original damage and monster damage will hit between 100% to 200% of its original damage (not applied to %HP attacks).

Authentic Symbols
Authentic Symbols can be leveled up to give more Authentic Force by equipping duplicated Authentic Symbols. Authentic Symbols can only be obtained from daily quests. Monsters will not drop any authentic symbols.

In addition, events may give out Authentic Symbol Selector coupons to exchange for a symbol of your choice (only the ones that you have obtained a symbol from quest are allowed to be chosen)

Both symbols and mesos are needed to increase the symbol level.
 * Required number of symbols to level up: $$9 \times SymbolLevel^2 + 20 \times SymbolLevel$$
 * Required mesos to level up
 * Cernium: $$96,900,000 + 88,500,000 \times SymbolLevel $$
 * Hotel Arcs: $$106,600,000 + 97,300,000 \times SymbolLevel $$

You can use a lower growth symbol to combine with a higher growth symbol at no additional cost, but mesos used on the lower growth symbol are not refunded. This makes it possible to exceed the required symbol for the next level, and the excess is carried over.
