Tabletop Caps - Unique Lord & Faction Rules - Submod

Submod to Tabletop Caps that addes special rules to all standard Lords and some Factions.

See above collection for supported modded LLs and recomended mods.

Some special rules are applied to lords and/or factions, but they never stack. For example, Boris LL in Boris Faction doesn't get double discount on War Bear Riders. All lords in his Faction gets the discount, or if you recruit Boris by another faction, then only Boris gets the discount.

Since the question has come up several time. When there is a lesser and a greater thematic unit to choose from, I rather make the lesser unit core, than to make the greater unit cheaper. Basically, I want you to use both units, if the greater unit cost the same as the lesser unit, you would never build the lesser unit. I think that even without reduction, chances are you will build some the greater unit anyway, than add in some lesser units as core.'
Examples; Slayers & Giant Slayers, Kroxigors & Sacred Kroxigors.

Some units that are reduced can not be recruited after confederation, you can use mods to get around that such as;
