# Pathfinder Arcanist vs Spellresistance

Arcanists have a class feature named Arcane Reservoir

Points from the arcanist reservoir are used to fuel many of the arcanist’s powers. In addition, the arcanist can expend 1 point from her arcane reservoir as a free action whenever she casts an arcanist spell. If she does, she can choose to increase the caster level by 1 or increase the spell’s DC by 1. She can expend no more than 1 point from her reservoir on a given spell in this way.

As you can see from this line

she can choose to increase the caster level by 1

my question now is does this increase in caster level for the spell also increase the caster level bonus for rolls against spell resistance.

This also applies to every other use of caster level in a spell—range or duration are the most common, but also pretty often damage, and more niche stuff like dispel checks. If the spell’s caster level goes up, all those things go up. For an increase in caster level to be limited to just certain ways, the bonus would have to say that, like “bonus to caster level for the purpose of $$\X\$$,” or whatever.
