Need help with D&D 3.5 Conversion

[Kaiseresc]

I want to play a Morninglord, from the Forgotten Realms - Player's Guide to Faerun.
I would adapt it to another god. But I don't know how to do the proper conversion. What should change and how? The only thing I know is that the skill ranks needed are reduced by 3 to a min of 1. Here's the class: http://dndtools.eu/classes/morninglord-of-lathander/

thanks in advance! At least I might learn a bit more of conversions. Can most things be converted? What could and what should not be converted, usually? Are there things, when converted, that become too overpowered?

You need to replace Turning with Channel Energy, otherwise it's fine. Subn Domain now has buffed Channeling instead so you can pick that ability.

This looks pretty easy, I think.

Requirements
Just chopping -3 to a min of 1 off the skill requirements would work fine, but it would also be fine to reinterpret them a little. For example, something like Knowledge (Religion) 5, Diplomacy 5, and either Craft or Perform 3 or so would suffice.

Improved Turning doesn't exist in Pathfinder, but its equivalent is probably Improved Channel. You might want to take a peek at the list of Channeling Feats to see if there's one that's more thematically appropriate. I think either Improved Channel or Turn Undead would be fine.

Just to be safe, you should probably put in a line about requiring the Channel Energy class feature. It's sort of implied with Improved Channel, but it should be specifically positive energy.

The spellcasting requirement seems fine as it is.

Hit Dice, BAB, and Skills
All look appropriate.

Weapon and Armor Proficiencies
No change needed here.

Spellcasting
Or here.

Bane of the Restless
This should just improve Channel Energy progression, with levels of Morninglord stacking with levels of any other class that grants the ability.

Lathander's Light
It might be best to rephrase this as altering any spell with the "light" descriptor with the effects of Widen Spell without altering its spell level or casting time. You can check out the text of the Holy Vindicator's "Faith Healing" power for an example of wording something like this.

Creative Fire
I'd consider reducing this to +1/2 your class level instead of +1/class level, but it's probably fine the way it is. Some Bards might get upset at being out-performed by a stuffy old Cleric, though.

Daylight
Fine.

Searing Ray
Also fine.

Greater Turning
Here we have a problem. The Sun Domain in Pathfinder no longer does the whole Greater Turning thing, so this needs to either be reworded to DO what Greater Turning does, or just do something else entirely. My suggestion is to upgrade the Daylight power as per the Sun Domain's "Nimbus of Light" power, which harms undead within its radius. Simple fix, still thematic, uses an existing Pathfinder mechanic, and is close enough to the original power to work.

Blessing of Dawn
Looks fine. Also, neat. ^__^

Maximize Turning
Should be okay, I think? Needs to be reworded along the lines of maximizing a Channel Positive Energy roll against Undead (whether used to damage them, or via the Turn Undead feat).

Rejuvination of the Morn
Probably fine, but could use some rewording, and ideally it should duplicate the effects of existing spells (like Heal). Ideally it should be 1/week, too, unless your setting uses tendays in this game, too.

Aura of Radiance
Looks fine. I'd maybe slip in a line about upgrading any existing Dakrvision to 90' or 120', so as not to shaft races that already have it, but I guess the colour vision is an upgrade anyway. Up to you/your GM, but when in doubt, leave it as is.

I think that about covers it! Balance-wise, it's actually pretty good at first glance.
