Wyrm wizards are spellcasters who learn new spells not through research and experimentation but rather by tapping into the vast wealth of arcane knowledge possessed by dragons.

Requirements

Class Features

Spellcasting: At every level other than 2nd, 4th, and 6th, you gain new spells per day and an increase in caster level (and spells known, if applicable) as if you had also gained a level in an arcane spellcasting class to which you belonged before adding the prestige class level. You do not, however, gain any other benefi t a character of that class would have gained. If you had more than one arcane spellcasting class before becoming a wyrm wizard, you must decide to which class to add each level for the purpose of determining spells per day, caster level, and spells known.

Knowledge of the Wyrm (Ex): You spend a great deal of time exploring the depths of a dragon's magical knowledge, giving you a distinct advantage over spellcasters who do not have the benefi t of draconic tutelage. Starting at 1st level, by spending at least 1 hour doing nothing but performing research, you can add your class level as an insight bonus on Knowledge (arcana) checks made for the next 8 hours. You need not consult with a dragon to gain this insight, though if you do, the insight bonus improves by 2.

At 5th level, you also gain this bonus on Spellcraft checks, for the same duration.

Spell Research (Ex): One of the greatest advantages that you gain from consulting draconic lore is the ability to unlock magical secrets forbidden to other wizards. Starting at 2nd level, select one spell from any class's spell list (including divine spells), of a level equal to or lower than the highest-level arcane spell you can prepare and cast. You can add this spell to your arcane spellcasting class spell list as a spell of the same level; all other aspects of the spell remain unchanged. At every even-numbered level thereafter, you gain the knowledge and use of one additional spell in this manner.

Draconic Discovery (Ex): At 3rd level, you make startling discoveries into the nature of magic thanks to the unique insight of your dragon mentors. Select any arcane spell of up to 2nd level that you are capable of preparing and casting, and any one metamagic feat you know (with a maximum spell slot adjustment of four). Once per day, you can apply the effect of that metamagic feat to the chosen spell without adjusting the spell slot of the spell or preparing it ahead of time.

At 6th level, you can select a second arcane spell (of up to 4th level) to gain this benefi t (choosing either the same or a different metamagic feat that you know). At 9th level, you can select a third arcane spell (of up to 6th level) to gain this benefi t, again selecting either the same or a different metamagic feat that you know.

Convert Counterspell (Su): Starting at 7th level, you can identify the components of an incoming spell instantaneously and convert stored arcane energy into a counterspell. You can lose any prepared spell of 3rd level or higher in order to cast dispel magic as a counterspell, or you can lose any prepared spell of 6th level or higher in order to cast greater dispel magic as a counterspell. This ability does not allow you to convert spells for general use into dispel magic and only applies to counterspelling. The normal rules for casting a counterspell still apply.

Break Spell Resistance (Su): At 10th level, you gain great insight into the way creatures naturally resist magic by studying the magical defenses of dragons. Whenever you succeed on a caster level check to overcome a target's spell resistance, you can lose a prepared spell as a free action to negate the target's spell resistance. The target loses its spell resistance for a number of rounds equal to the level of the spell you expended.
