Thanks, people. I was thinking mainly cleric, and GiantOctopodes's build sounds great. But sorcerer path sounds intriguing. I haven't started a new game yet, so choices, choices, choices.
Glad I could help! Out of curiosity, the melee build or the spell build?
Just so folks are aware, the difference between Tempest Cleric 6+ / Storm Sorc 3+ and Storm Sorc 6+ / Tempest Cleric 2+ is Thunderbolt Strike vs Heart of the Storm.
Storm Sorc 6+ you get a 6m AOE doing 1/2 Sorc level damage when casting a leveled spell dealing thunder or lightning damage (so in DumbleDorfs build 4 damage), which can be helpful for triggering Cull the Weak on small enemies, but otherwise isn't a ton of damage but never hurts. You also get Thunder / Lightning resist.
Meanwhile Tempest Cleric 6+ gets Thunderbolt Strike, which gives the option of pushing back any large or smaller creature you damage with thunder or lightning by 3m, no saves, no limit on usage. Use a lightning spell or shoot just fire off a lightning arrow, doesn't matter if they save for half damage, taking just one point will be enough to knock them back, letting you push them off cliffs, roofs, rafters, or whatever other perch they might be sitting on. Or shoving them together for more nuking, or pushing them through Spike Growth or other hazardous terrain for massive damage, the options are endless.
I get that Sorc 8 / Wiz 2 / Cleric 2 gives 2 feats instead of 1, but imho you get the worse of the two abilities, and Wizard is your damage dealer anyway, so if getting that 2nd feat were that important to me I'd go Tempest Cleric 6/ Storm Sorc 4 / Evo 2 before I would go primarily Storm Sorc. Keeps Quicken, keeps all the important features, gets 2 feats, you just lose 4th level Cleric spells. Could also go Cleric 8 / Storm Sorc 3 / Wiz 1 if you wanted to keep the 4th level spells, the Evocation shape spells is nice but not required if you're careful enough / don't care that much about your teammates XD 4th level Cleric spells are ok but not likely to be your first or even 2nd choice for what to cast so I'd do the former personally.
