abob101 is being modest and not mentioning his very fun Demon and Wizards mod. Webusver has a patch to use D&W with his mod, as well.

I just stripped my FE:LH game of all mods to give dsraider's Blood and Mana by itself a play-through and it is very good. His new traits and abilities really make your build choices more meaningful/fun.
Monuments XP1 - tjashen
Black Market Bazaar - Hellions
Armored Militia, Snaking, Swamp Tiles - Parrotmath
Are all great mods as well.
Have fun!
