Engineering Quarter

Engineering Quarter is one of the game's most important buildings. You can upgrade Towers here as well as research new towers and give them new skills and talents.

Improving Towers

Your Towers can be improved in three ways:

• Fortify: Makes your towers stronger. It requires gold and resources (first Rainbow Ore, then Fairy Wood, and later Black Gold). These are won from world levels and Level Taxes. Plus there is a cooldown between tower upgrades, which means you cannot improve many levels at once. You have to do it little by little. Each upgrade adds some minutes based on the current level (for example 15 minutes when upgrading from level 19 to 20, or 30 minutes when upgrading from level 20 to 21), and when the timer passes 1 hour you need to wait. In practice this means that you can make a limited number of consecutive upgrades before you have to wait. As with all timers you can use Diamonds to speed things up.
• Research: Unlocks new towers. Requires Gold (or specific items in Facebook), Dark Soul Crystal and Notch Rock
• Talents: Unlocked at Kingdom Level 30, require Stars and Tear of Shiva

NOTE: The game terminology treats the starting towers as tier 0, the first upgrade as tier 1, and the maximum upgrade tier 3 towers. These towers can each gain up to two special skills, but this does not change the tier.

Fortify

Every upgrade increases Tower Damage (and HP for Barracks) and gives it 1 Star. 4 Stars raises Tower to the next level.

For Arrow, Mage and Cannoner Towers up until level 60 each upgrade increases damage by 4% points or higher (most of the time) or 5% points. For example, upgrading Cannoners from level 14-2 stars to level 14-3 stars changes the bonus from 249% to 254%.

Starting with level 60 each upgrade increases base damage by 8%. For example, upgrading Mage Towers from level 60-0 stars to level 60-1 star changes the bonus from 1091% to 1099%; upgrading Cannoners from level 61-0 stars to level 61-1 star changes the bonus from 1123% to 1131%; upgrading Arrow towers from level 61-2 stars to level 61-3 stars changes the bonus from 1139% to 1147%.

For Barracks - damage by 3% points and 16 HP most of the time, with an occasional 4% points and 17HP (or higher). For example, upgrading Barracks from level 16-3 stars to Level 17-no stars changes the damage from 196% to 200% and HP from 1023 to 1040.

Starting with level 60 each upgrade increases damage by 6% and 32 HP (occasionally 33 HP). For example, upgrading Barracks from level 60-0 stars to level 60-1 star changes the damage from 737% to 743% and the HP bonus from 3835 to 3867; upgrading Barracks from level 60-1 star to level 60-2 stars changes the damage from 743% to 749% (+6%) and the HP bonus from 3867 to 3900 (+33).

Research

Research unlocks the higher tiers and skills of the towers.

Note: Tier 3 Towers do not have any special effects beyond the normal damage and range increase until those effects are researched at the Engineering Quarter and then enabled in battle at the cost of some goods. For example, an Oiler will not actually cause a slow effect on mobs until its Jumbo Vat ability is activated.

Talents

Unlock at Kingdom Level 30

Each tower has 5 talents and all talents are limited to level 10 as maximum.

To upgrade all talents, you need 600 Stars and 24,000 Tear of Shiva.

Strategy: Tears of Shiva are more useful here than on Soldier upgrades, since they not only increase Battle Power but also improve the tower defense part of the game.

Star	Yellow stars earned from world map battles
Tear of Shiva	Purchase from the Jewel Crafter, 50% chance to get from ransom in the Prison, can be obtained from the Crown Port when exploring a Mining Area, Woodlands or an Animal Herd (2 at a time, and must win a fight against a particular monster)

     "From the shadows..."

   Rangers that choose the path of the sniper, they shoot from distances dealing heavy damage to single targets.

     Fly cutter - The King of Towers

   • Explosive Shot : Designed to explode on impact, these bullets leave their target burning.(active skill: One of the assassins throws a bomb that creates a large burning area on the ground. Anything standing in the flames will continue to receive damage. Seems to be a relatively short cooldown, and the two assassins in the tower each have their own bombs. Multiple flaming grounds stack on the damage, so an enemy standing in the middle of five fires dies very quickly) (burning damage increased per upgrades). "Kaboom!"

Basic barracks used to house new recruits. Do not confuse with Barracks, the building used to recruit soldiers for the PVP part of the game.

Cannot attack fliers, except Coliseum (Gladiators) if they have the Pike upgrade, and Clergymen from the Hall of Divinity.

(Works best to stall fast but weak enemies so other towers have time to kill them before they get past the tower. Or to stall some enemies until others arrive so they're all bunched up for AOE towers and Blizzard to hit. On bosses who kill even Sir Lance Alotte in one hit, a cheap Tier 1 Guard Barrack stalls them just as well as an expensive Tier 4 Cavalry Quarters or Coliseum)

• Broiling Flames : A super heated bullet dealing 3000~5000 damage in an area when enemies dies. Upgrades to 9000-15000 damage. Unfortunately this is a fixed number, so its percentage increase in tower damage will decrease with tower levels. "Can you feel the heat?"
• (passive skill: The enemy hit directly by the dragon receives a debuff with a flame icon above its head. On death, that enemy deals some damage around it to other enemies. Note that only the direct target of the dragon hit by it, not the splash damage on any other enemies near it, receives this debuff).
