Help me understand cleric spells

[Lamprey]

Hi guys,

Stupid newb question. I remember, from playing way back in the day, that casters would get their spells every few levels (mages get spells at 4, 8, 12, etc.). I thought priests got their spells the same way, at lvl 5, 9, 14, 19, etc. But when I look up eq1 cleric spells, they're listed for each level - there's some lvl 1 spells, some lvl 2, 3, and so on.

So what's the deal? Does my lvl 3 cleric need to hit 5 before being able to upgrade spells? Could anyone clear this up for me? Thanks!
