You know, you can like tweak it a bit. Like if your a Cleric and your blessing/crafting a Divine Reliquary, you would swap out the Arcane skill for the Religion skill. If your a druid, you'd swap it out for Nature Skill.
I would recommend to go for ones that cover areas of 5E that you find lacking/needing or for stuff that is regularly part of it.
Looking for Monsters? Kobold Press Tome of Beasts 1-3/Creature Crucible, Deadly Denizens, and Monster Manuals Expanded 1-3 are your best bet.

Teknoman(US)/Tekkaman Blade(JP) was pretty awesome. I like both the American Theme and the original Japanese theme for the first half of the series cuz they were both bangers in their own rights.
