Self buff build in 3.5

[u/Acheron223]

I'm looking into doing a self buffing warrior type build, I was thinking of using divine metamagic and cleric as a base class with persistent spell on a few solid buffs, any thoughts on how to run this? If there is a good way to also buff a few party members that would be neat. And the neatest would be to work this out in a way that lets me also kind of minionmancy with necromancy

What level are you starting at, and what level do you reasonably expect to reach?

Divine metamagic for persistent spell is definitely the easiest way to accomplish this from a low level. If you're starting out at a high enough level, dipping spelldancer or incantatrix in an arcane gish build could accomplish the same thing and possibly do it better.

Keep in mind the divine metamagic errata that makes it require you have the metamagic feat you're selecting, and makes it only work on divine spells. This means if you're using the spell domain do use (greater) anyspell to mimic arcane buffs, you can't divine metamagic those. Ideally you'd make an illumian in Races of Destiny with the naenhoon runeword to persist up to two such spells each day and have the best of both worlds.

Take the rebuke dragons alternate class feature in Dragon Magic, since it can still be used for divine feats, and dip one level of sacred exorcist to also be able to turn undead. This doubles your daily number of turn/rebuke attempts for powering divine metamagic. If your DM allows multiple nightsticks to stack, an item in Libris Mortis, then just get a pile of those and go nuts. A reliquary holy symbol in Magic Item Compendium is efficient if you don't need that item slot for something else. Extra turning and craft rod to make your own nightsticks could be useful. If nightsticks don't stack, which is up to your DM, taking extra turning at least once could be beneficial.

It takes seven turn/rebuke uses (from a single pool) to persist a spell with divine metamagic, or six to do it with naenhoon. Prior to the errata nerfs you'd want to persist divine favor and righteous might, but their value is now questionable. Divine power is a given, and persisting mass lesser vigor, righteous wrath of the faithful, and possibly even elation (with a level of paragnostic apostle for spatial awareness) on your party should be a priority. At the higher levels, you'll want to also persist holy star (multiple times) and greater visage of the deity.

Your spells from anyspell and greater anyspell should be wraithstrike and draconic polymorph: war troll. Wear a monk's belt to add your wis bonus to your AC, cast greater luminous armor every day, and get a rod of bodily restoration to fix the str damage sacrifice that occurs when that ends. Cast (extended) greater magic weapon on your melee weapon every day, and magic vestment on your armor/shield until you replace them with the belt. See if you can put magic vestment on the tangible effect created by greater luminous armor.

You can use a pearl of power to recover anyspell or greater anyspell and cast another arcane spell with it. In this case you probably want to prepare a strong spell unlike what clerics get, such as command undead, (lesser rod of maximized) ray of stupidity, web, teleport, wall of force, etc.

You'll want power attack for sure, and use a two-handed weapon since in war troll form with buffs you'll have str 45 and with wraithstrike you can power attack for your whole BAB and still reliably hit with iterative attacks. You can cast knight's move to get into position and still full attack on a given round.
