There seems to be some BIG confusion on bonuses per levels. Not the
just the one that say " +1 per level". All the abilities, spells, feats,
schools and domains, that say you get a +1 per every 2, 3, 4 levels of the caster and so forth. Some GM's I have played in games with read it
literally, such as with Force Missile , you get 1D4 +1 at first level
+1 per every 2 levels . Then you would not get the next +1 until level
4. Then some GM's read it like the spell Magic Missile where you get the +1 for every 2 levels that the character has gained past the level that
he/she aquired the ability. Making it at 3rd, 5th, and so forth.
The latter makes sense when you read some descriptions that say when the
max is reached.
I believe that you get the base at the level you pick up the ability and
then add the bonus at each step of character level gain.
But this would make a Type-O in the Magus archetype of Blackblade. The
Magus aquires the Blackblade at level 3 and the Int starts at 10 but
then it says it gets a +1 to INT per every 2 levels of the Magus ( 3rd,
5th, and so forth. Wouldnt it be the +1 at 5th , 7th and so forth?
I am playing a level 3 Wizard / Evoker and have that problem.
