The 5 Elements

There are currently 5 elements, 3 form a triangle, Fire>Earth>Ice>Fire, however Dark and Light get a buff against each other.

It is important to note that the translation on the beginning of the game about this rule is wrong. It says that Light and Dark is strong against each other on front row. It actually mean Light and Dark do is strong against each other when Attacking. That is, the Light servant should be on Attacker's side (left side) to have an advantage against Dark. It also says that Light and Dark have advantages over Fire, Ice and Earth on back row, it should be Defending instead.

For Easy, Normal and Hard difficulties we have a rather different damage table:

In formulas above the Level Multiplier [Lvl] = 1 for Easy, [Lvl] = 2 for Normal, [Lvl] = 3 for Hard and [Lvl] = 4 for Very Hard (Hell) difficulties.
