+The DC is determined by the GM and based on the difficulty of the action; it can either be static (based on an obstacle) or opposed (like rolling against another character). You succeed if you meet or exceed the DC. The default DC is 11, and any check that doesn't specify always uses that number. However, the GM may set that target to be anywhere between 5 and 20. The GM may also rule that a task is impossible or so simple that it doesn’t require a check.

+===== Criticals =====
+Any roll of a 20 on a D20 is considered to be a critical success, automatically succeeding. Any roll of a 1 on a D20 is considered to be a critical failure, automatically failing. These special rolls are particularly important because of their effect on the [[durability]] of PC's armor and weapons.

 Some circumstances can cause a check to be
 rolled at advantage or disadvantage. Many spell effects don't have a save, but rather require a successful magical attack against the target.
+=====Magic Attack Roll=====
+Magical attack rolls are rolled by a spell-casting character on 1D20, adding his Intelligence modifier (Scholars) or Wisdom modifier (Zealots) plus his proficiency bonus.  The result must exceed the defender's defense.  Monsters calculate the defense by adding either their Weak, Normal or Strong modifier (depending on the monster type) to a base of 10.  On monster stats in this wiki, that defense rating is called "Resistance" and applies to all spells or spell-like attacks, regardless of type.  For spell attack rolls made against a PC or [[hench|henchman]], or NPC with full PC class stats, the defense against a spell attack is calculated as 10 plus one ability score modifier chosen by the DM based on the nature of spell (usually either DEX or WIS, but sometimes others) plus his proficiency bonus if the PC or henchman's class is proficient using that particular ability.
