Following that is a list of when an item is first available after the start of the game. The maximum number of items sold is listed in [ ].

Scroll of Regeneration
After battle, return to your town and buy a Scroll of Regeneration. Then you're prepared for the next fight. Many advanced Human players have worked this into their regular playing.

Counter: have a unit attack (physical or damage with spell) each enemy unit under the effect of Regeneration. This will cancel it!

Lesser Clarity Potion
This is useful for regenerating Heroes' mana between battles. After a battle come back to your town and buy a Scroll of Regeneration. Use it, and also buy some Lesser Clarity Potions.

During battle run your Hero away, use Clarity, and then come back. You can also keep the Hero in the back away from combat and still use Clarity during combat.

Clarity vs Mana Potions. Mana Potions heal instantly and can't be stopped. So they are great during battle. Clarity potions are cheaper (100 Mana for 70 Gold vs 150 for 200 Gold) but it takes longer for them to work and they can be canceled.

Mechanical Critter
This is used for scouting. When people see a Critter many don't think it's actually a player unit in disguise. When playing against Human players, kill all Critters!

Send a Mechanical Critter into an enemy town then use Mass Teleport to teleport to it!

Counter: Kill any Critters you see!

Ivory Tower
This is useful for setting up Towers in a hurry, or without a Peasant so that you can defend expansions or offensive tower.
