First all of this is a roughdraft, a first attempt at fitting in cleric domains to DDO. I plan to make changes to this as the thread progresses and suggestions are offered up. This is a giant undertaking and I don't expect it to be balanced/finalized in a day.
Domains are choosen as feats at levels 9 and 18, the feats offer varying bonuses I tried to balance vs the enhancement lines they unlock.
The SLA enhancement lines are dependent so you have to get the preceding two to be able to take the third for example. I went 1 2 3 with AP costs but I could see 3 2 1 or 1 1 1 as being reasonable.
Also for SLAs their balance is mostly dependant on their cooldowns, for most I think their natural cooldowns are reasonable but theres a few like bladebarrier that would need a longer then natural cooldown. 5 SP Base, no free metas.
Eberron has always played fast and loose with alignments so I included the evil domain despite our lack of being evil.
