advanced Building

I just wanted to know if there is a way to give the peasent a advanced building option like in NCCD. (with out using jass)

You could just make another unit that can only buid advanced units.

Try using the spellbook ability to 'summon' "Advanced" buildings?

there are 2 options:
1) have a spellbook filled with "build tiny" abilities.
2) have a bear form ability that transforms your worker into an advanced worker that has different buildings.

basiclly therew the Tried and true method of having you basic builder build a build or two and build the new " Summoner" from there

Look in the download section for a spell nemad "Advanced Building", by me. It works fine for me. It's not jass, just basic triggering.
