Runeblaster: A Handbook for the D&D 3.5 Runecaster

[Saintheart]

Attributes

For a Cleric or Druid method of entry:
STR: Important stat if you’re focusing on melee combat. If you’re going ranged or you’re not planning on being involved in damage dealing of combat, much less so.
DEX: You came in here via cleric. You’re proficient with heavy armour. Use it.
CON: Blue stat regardless of class, especially so for the Runecaster who gets the same hit dice as a cleric.
INT: This has to be a minimum of 13 to get you Inscribe Rune, so you’re stuck with it. And Craft keys off the INT skill anyway, so this is the biggest difference from the bog-standard Cleric advice to dump this.
WIS: You’re a divine-based caster, so boost your primary stat.
CHA: Dump it. Yes. I mean it. Stop trembling and pointing at your handbook where it says a cleric can’t live without a huge Turn Undead bank balance to power Divine Metamagic. You can make permanent runes that are touch-activated. Seriously, the idea with a Runecaster is to carry your spells around with you all day long, not carry them in your CHA bonus and Nightsticks.

For an Archivist method of entry:
STR: Dump it, unless you plan on being a gish of some kind.
DEX: Handy to boost your horrible Reflex save and for ranged touch attacks.
CON: Blue stat regardless of class, though you got an improvement on hitpoints the moment you became a Runecaster.
INT: This would already be a primary stat for you, and it’ll still be important because it still controls your spell DCs. Not to mention you need 13 in it for Inscribe Rune and your Craft checks key off it.
WIS: This controls your bonus spells per day as an Archivist, so it’s important to raise it.
CHA: Again, dump it unless you’re desperately needed for Diplomacy. You can't turn undead, so you can't get Divine Metamagic anyway.
