I found myself exposed to lyrium over and over, finally the metal around the chest seems to start to have a slight blue glow
I now feel that my magic has expanded, I am now what many would consider an Arcane Mimic.
My advancement:
I now can take sorceror (as my mimic bloodline has been founded and will be passed onto offspring).
I gain the ability of arcane bloodline, When I bleed on someone they must make a Ref save DC (15), if they succeed they take half, if they fail they take 2d6 worth of acid damage and any magic items this hits will also take half the damage dealt. Normal items take full damage. This starts at level 10 for my first child-birthing story.
Hatred of a thousand slugs: Favored enemy (Vermin type) I gain a +2 bonus on Bluff, Listen, Sense Motive, Spot, and Survival checks when using these skills against creatures of this type. Likewise, I get a +2 bonus on weapon damage rolls against such creatures.
Magical understanding, I can now 3/day cast Detect Magic (CL 1)
Psuedopod growth: My pseudopods now glows slightly blue, doubling its damage dealt to 2d6+4 and giving it the effect of acting as a magical weapon when resistance is considered
Arcane Blood: Once per day, if a creature that I can see within 60ft of me casts a spell I already know. I can use an immediate action to cast the same spell back, sacrificing my highest spell slot available in exchange for the countering the spell. Spells limited to 5th level that this ability can effect. (edited)
