fix: exori gran con damage bonus

[mdbeng]

this fixes the excessive damage output from skill wheel such as enhanced ethereal spear, the damage output still too high in comparison to real tibia. ( the high output is on all the spells boosted by skill wheel )

This fixes Issue #3313
Aided by " @lBaah " Much appreciated.

Description

Before this PR using boosted spells from skill wheel will result in high damage output 9.000 +
This will prevent this from happening but the damage output still a little too high for realistic purposes.

Behaviour

Do this and that doesn't happens

Expected

Do this and that happens
