Not exactly. If level is the only thing wrong, they can make a caster level check.Patryn of Elvenshae said:For instance, take a CL 1 scroll of Cure Light Wounds, Divine. This scroll may be used by any cleric or druid, and by any paladin or ranger of 4th-level or higher. Anyone else wishing to use it must make a Use Magic Device check in order to do so.
If she meets all three requirements but her own caster level is lower than the scroll spell’s caster level, then she has to make a caster level check (DC = scroll’s caster level + 1) to cast the spell successfully. If she fails, she must make a DC 5 Wisdom check to avoid a mishap (see Scroll Mishaps, below). A natural roll of 1 always fails, whatever the modifiers.
Not exactly; no caster level (the case of a Range or Paladin before level 4) is not the same thing as a caster level of 0. The 2nd level Paladin does not have a caster level, and therefore can't make a caster level check to cast the spell from the scroll.CyberSpyder said:Not exactly.

Kirin'Tor said:Actually, according to the PHB, the paladin's caster level is equal to 1/2 his paladin level (same for ranger), so at first level a Paladin has caster level 0, and at 2nd he has 1.

Kirin'Tor said:Only Fighter, Barbarian, and Rouge have 'no caster level' (can't make CL checks). Every other class can.
