Saving Throw and SR Elements

All chaos magic spells have a base saving throw Difficulty Class equal to 10 + the caster's Charisma modifier + 1/2 the caster's level. This means most chaos magic spells will be far easier to resist than a spell cast by a static mage of a similar level. Static magic has had milennia to perfect the penetration capability of its spells, whilst chaos magic is often spun in not more then a few seconds.

Chaos mages may, however, focus the chaos at their command into a more potent spell with a higher saving throw difficulty class. This raises the Casting DC of the spell itself, as detailed below.

-1 Penalty to Subject's Save

The Casting DC is modified by +2, whilst the target receives a -1 penalty to its save

-2 Penalty to Subject's Save

The Casting DC is modified by +5, whilst the target receives a -2 penalty to its save

-3 Penalty to Subject's Save

The Casting DC is modified by +10, whilst the target receives a -3 penalty to its save

-4 Penalty to Subject's Save

The Casting DC is modified by +15, whilst the target receives a -4 penalty to its save

-5 Penalty to Subject's Save

The Casting DC is modified by +20, whilst the target receives a -5 penalty to its save

Overcomming Spell Resistance

Enemies possessing spell resistance can prove a particualer problem for mages, as such defences reder magic almost useless. Chaos mages can worm their spells through these defences, however, using twisting strands of chaos to thread their way through an enemy's natural resistance, but the cost is great

To overcome a subject's spell resistance, and avoid the necessity of making the required caster level check, add the SR to the Casting DC.
