[Warhammer] Magic Casting - House Rules

The spell casting rules requiire multiple success levels for most spells beyond petty cantrips, but my group and I have noticed that this is super lame in play. The wizard has the same chance as anyone to succeed, like 45-50 being well trained, and then most of the spells are not more powerful than a single attack. This has let to dissatisfaction from the wizard player, which I am sympathetic to. So, tinkering with it a bit, I'm going to try the following house rules.

Casting Rules

Spells no longer require casting levels. Instead, some more powerful spells are more difficult. Additional Success Levels (SLs) have the effects listed in the spell descriptions as normal.

• CN0: +20 Average.
• CN1 to CN4: +0 Challenging
• CN5 to CN7: -10 Difficult
• CN8 to CN9: -20 Hard
• CN10+: -30 Very Hard

Channeling: channeling successes add magical Advantage to any subsequent channeling or casting attempts, each SL adding +1 Advantage. This Advantage is only lost if the channeling or casting test is interrupted or there is a critical failure, as normal. Thus, 4 SLs on a channeling test will add +40 to the subsequent casting roll, or can be banked/saved while the caster attempts another channeling test the next round. So, if a caster gains 2 channelling successes one round, none the second, and 1 a third round, when she rolls her casting roll the next round, she has +30. Critical successes and Fumbles occur as normal while channelling.
