Formula that calculates the chance of removing AoE

base_chance VS d100

If AoE owner tries to dispel his AoE base_chance = 100%. If NPC tries to dispel AoE he get 30% bonus to base_chance.

Notes

• Dispel does not remove spells with negative effects.
• If used as an area of effect then dispel will attempt to remove half of the usual number of spells.
