Feat Progression:
Level 1-
Abjuration Focused (Knowingly or unknowingly via jargon and hidden messages from their method of instruction (be it a book or a teacher), Magic Slayers derive their spell-like abilities from the school of abjuration. As they are highly focused on this one school of magic for the purposes of fighting magic users, they forgo all other kinds of magic. They cannot use any spells, feats, or items which derive use from any school of magic but abjuration. They do not require verbal or somatic components to cast their class' spell-like abilities, and as such can cast them when silenced or when wearing armor.).
Locate Magic 1/day, 2/day at level 4, 3/day at level 8 (Magic Slayers learn how to locate magical auras, in order to find their intended victims. They gain Detect Magic as an abjuration spell, instead of a divination spell. At level 9, this functions as a "See Invisibility" effect as well for as long as the "Detect Magic" effect lasts.)
Level 2-
Dispel Magic 1/day, 2/day at level 6, 3/day at level 10 (One of the most basic of their abilities, Magic Slayers who have delved into their training first learn how fight mages by dissipating their magic. The Magic Slayer gains a special form of greater dispel magic, with an effective caster level based on their character level.)
Level 4-
Spell Defense 1/Day (The Magic Slayer, after continuing their practice, learns how to defend themselves against magical attacks. They can cast spell resistance as a spell-like ability, based on their character level.)
Level 5-
Anti-Ward Strike (The Magic Slayer learns how to attack warded targets in a more effective manner, dealing an additional 1d4 damage to any target who is warded. At level 8, they gain 2 more attack bonus against warded targets. At level 10, each strike against warded targets decreases their concentration by (1/10) the damage dealt for 1 round.)
Avert Escape 1/day, 2/day at level 10 (The Magic Slayer learns how to prevent an enemy from utilizing magical escape techniques. The Slayer can cast Dimensional Anchor as a spell-like ability. This ability is cast at an effective caster level equal to the Magic Slayer's character level.)
Level 7-
Advanced Spell Defense 1/day, 2/day at level 10 (The Magic Slayer, now adept at defending themselves against magical attacks, can a spell-mantle like effect that shields them from a number of spell levels equal to (Magic Slayer Levels+1d6). Casting this will dispel any spell resistance on the Magic Slayer as the Slayer shifts to a more solid, but short lasting defense.).
Level 9-
Protection from Magic 1/day (Magic Slayers can learn one of the following abjuration spells as a spell-like ability: Lesser Mind Blank, Protection from Spells, or Freedom of Movement. Each have an equivalent caster level of the Magic Slayer's character level. The Magic Slayer also gains Resistance: Magic 5/- for the duration of this spell-like ability, when it is cast.)
Level 10-
Breach Magic (The Magic Slayer may now use a use of their Dispel Magic to breach 2 protections on a target. This breach does not lower their spell resistance, but instead lowers their concentration by the same amount (3 for 10 rounds).)
Seal Portal (The Magic Slayer can choose to use the principles of Dimensional Anchor to lock a portal shut instead. This requires more effort, and uses 2 uses of Avert Escape. The Slayer can cast Seal Portal as a spell like ability. This ability is cast at an effective caster level equal to the Magic Slayer's character level.)
