Temple of Khorne
Khorne abhors magic and as such his temple is a magical vacuum. All spells cast in the temple will be extremely difficult to make manifest. Every time a spell casting warrior wishes to use magic, roll on the following table:
1-2 Spell cannot be cast this turn
3 Spell costs 3 extra power to cast this turn
4 Spell costs 2 extra power to cast this turn
5 Spell costs 1 extra power to cast this turn
6 Spell is cast as normal
Note that only spells and spell casting magic items adhere to this rule. Magic weapons, armour and other magical treasure function as normal.
