Your guides are always good stuff. Here are my thoughts:
Forge Domain - This looks very attractive for the Cleric1/Wiz X; not so much for the searing smite, but for the AC boost over other cleric domains with heavy armor proficiency. Maybe it isn’t exclusively Dwarfy themed - I’m about the start playing a rock gnome cleric 1/wiz x, and the domain seems to match the flavor of the tinkering rock gnome somewhat well.
Insightful Fighting (3rd): Use your bonus action to potentially get sneak attack against an opponent you normally wouldn’t get sneak attack against. When I’ve played rogues, the occasion for this would not occur often. When you don’t have an ally within 5’ of an enemy, often you can use cunning action for a hide/attack from hidden quick advantage. Not saying this will never come up, but I don’t think it will come up a lot.
I’m hoping to not derail discussion much here. It has been argued that you can’t successfully hide when opponents can see you attempting to hide (excluding some sort of special, DM-approved distraction). Even though cunning action allows you to take the hide action in combat quickly, it doesn’t make the action always work. I became aware of this when I watched a Youtube video by DawnforgedCast called How Stealth Works in Dungeons and Dragons. (I’m not sure about linking rules here) That video and comments offers a more complete discussion than I should attempt here. The point of the whole thing is: if a DM decides on a tight interpretation of hiding rules, then Insightful Fighting is more useful than you thought.
I agree with you, that much point for the game designers to create this ability if rogues can already freely hide in combat.
I guess this is sad music, but without cues from listening to a person speak it is confusing. The color coding helps clarify this and the occasional sarcasm elsewhere in the document. This guide has a more upbeat and playful tone than your wizard guide. (See, I had a good thing to say about the colors!)
The description of Elven Accuracy cuts off mid-sentence. No big deal, as the thought is mostly complete already. After re-reading a few times I suspect that you may have intentionally stopped for a segue for the gnome feat. If so, then it is a bit confusing since a character can’t normally get both of those feats. An ellipsis might help….
Prodigy - I’m no expert on grappling, but prodigy may be highly prized for the option to get expertise athletics without multiclassing.
Toll the Dead – Any Death domain clerics will take note of a new necromancy cantrip for the Reaper ability. Toll outclasses Chill Touch, and sounds an upgrade for the domain’s offence.
