Spell hindrance
Spell hindrance is a system that imparts a chance for heavier armors to prevent spells from being successfully cast.
Robes, light leather, and full leather armors allow spells from all circles to be cast with no hindrance. Reinforced leather and double leather cause hindrance for some elemental and mental spell circles. Characters wearing leather breastplate or heavier armor will incur at least some hindrance for spells cast from any spell circle.
Casters wearing heavier armors will experience a random chance of spell failure. A base mana cost will be taken, stance will be forced down from defensive, and the standard 3 second cast roundtime takes place, but there is no further effect:
You trace a sign while beseeching the spirits to empower you with the Bind spell...
Your spell is ready.
You gesture at a skeletal lord.
[Spell Hindrance for some marbled pink mithril armor is 9% with current Armor Use skill, d100= 7]
Your armor prevents the spell from working correctly.
Cast Roundtime 3 Seconds.
(Forcing stance down to guarded)
The percentage of chance is variable based on the type of spell and type of armor.
Reducing Hindrance
Each point of base hindrance is increased by (base hindrance / 20) per point of Armor Use bonus away from the required amount. Base hindrance is the minimum hindrance that can be attained with enough Armor Use (i.e., 20 bonus * Base Hindrance).
Hindrance can be additionally reduced both by the spell Faith's Clarity (1603) and by the paladin's armor specialization Armored Fluidity.
Hindrance is entirely negated in natural sanctuaries and areas where Minor Sanctuary (213) is in effect.
