Casting

From LiMaWiki

In order to cast a spell or special ability, the caster must beat the spell's CAST DC.

To beat the CAST DC the character rolls a 1d20, applies her WSKL attribute, and any Specialization or Mastery skills. If the caster critically fails a cast by rolling a 1, the spell goes haywire and the DM rolls on the Spell Failure table. If the character succeeds, the spell is cast.

As spells are increased in level, the difficulty to cast that spell gets harder. For every level past the first, the CAST DC is increased by +1. For example, when a spell reaches level two, the CAST DC is increased by +1 making it just a bit harder for the character to cast.

Specialization and Mastery skills allow characters to add in a bonus when using a particular spell of that sub type. For example, if you where to have Fire Specialization under black magic at rank 1, any fire spell from the Black Magic spells would have a +1 bonus to reduce the CAST DC.

Warrior Abilities differ slightly in variation to normal casting. Certain warrior abilities require both a cast and the warrior to then strike a target. Such situations require a normal cast then a normal roll to strike. If the ability requires the warrior to strike after casting the spell, it will list so under it. Other abilities, while directly magical, may not require a CAST DC. Casting is exactly the same for those with a CAST DC, it's a 1d20 + WSKL however there is no specialization or mastery for warrior abilities.

The short version is this:

1d20 + WSKL + Mastery = Cast

If Cast is higher than the CAST DC of the spell, it fires.
