Requirements

Class Features

Weapon and Armor Proficiency: You gain no new proficiency with weapons, armor, or shields.

Spellcasting: At each Olin Gisir level, 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 that granted you access to 3rd-level spells before you added the prestige class level. You do not, however, gain any other benefit a character of that class would have gained. If you have access to 3rd-level spells from more than one arcane spellcasting class when you gain a level as an Olin Gisir, you must decide to which class to add each level for the purpose of determining spells per day, caster level, and spells known.

Ancient Knowledge (Ex): You have studied ancient lore in considerable depth. You gain a +1 bonus on all Knowledge (arcana), Knowledge (history), and Use Magic Device checks. You also gain the same bonus on bardic knowledge checks if you possess that class feature. The bonus increases to +2 at 4th level, to +3 at 7th level, and to +4 at 10th level.

Secret (Ex): You have picked up countless bits of forgotten lore from ancient tomes you have uncovered, the whispers of imprisoned fiends you have been set to guard, and other even more dangerous sources. Add your Intelligence modifier to your Olin Gisir level. You can choose any one secret for which that result equals or exceeds the number in the left column of the table below. You can choose another secret in the same manner at 4th, 7th, and 10th level, though you may not select the same secret more than once.

Signs and Portents (Sp): At 2nd level, you learn to ferret out ancient, hidden evils by reading mystic omens in the world around you. Three times per day, you can use augury, as the spell (caster level equals your character level).

Word of Dispel (Sp): At 5th level, you gain additional power against the old perils you seek to destroy or subdue. You can add dispel chaos, dispel evil, or dispel law (your choice) to the 5th-level arcane spells that you can cast. If you cast spells as a wizard, you simply add the spell to your spellbook. If you cast spells as a sorcerer, you acquire it as a bonus spell known at that level. The spell you have chosen is now an arcane spell for you.

Word of Might (Sp): At 8th level, you can use words of power against your enemies. You can add dictum, holy word, or word of chaos (your choice) to the 7th-level arcane spells that you can cast. If you cast spells as a wizard, you simply add the spell to your spellbook. If you cast spells as a sorcerer, you acquire it as a bonus spell known at that level. The spell you have chosen is now an arcane spell for you.
