Bonus spell damage

• Bonus spell damage is applied to spell (Psion and Elemental) attacks only.
• Percentage bonus is applied before non-percentage bonus. For example, say a spell should do 50 damage and the hero has +10%, +10, the damage would be 50*1.1+10=65.
• Amounts for Skills are affected by S, the number of skill points invested in the skill.
• Note that spells are still governed by their intrinsic damage caps, though percentage increases also increase the cap.
