With this order, you can research a unit, a type of unit, an item, a type of item, an avatar or a type of avatar. You can research up to four of these with one order.

Researching a specific unit or a unit type gives you a report on its race,
combat abilities, MPs, community size requirement, and gold cost. Even though
you may research a specific unit with this order, the information gained
applies to all units of that type. When researching a unit, it must be alive
for this order to be successful. This order costs your treasury 5 gold per unit
or unit type researched.
Researching a specific item or an item type tells you its combat bonuses, MP
bonuses, community size requirement, and gold cost. It also reports on which
races can craft that type of item, if it can be crafted. This order costs your
treasury 5 gold per item or item type researched.
Researching a specific avatar or an avatar type gives you a report on its
combat abilities, MPs, and description. This order costs your treasury 20 gold
per avatar or avatar type researched.
