Heroes

What Are Heroes?
Heroes are units that you can purchase with Gems, and they each help you out in different ways. All heroes have a passive and active ability, and they keep their levels through War Tortoise Ascensions. You can have up to three Heroes active at the same time. There are both melee and ranged heroes, and they will be visible on the battlefield when active. There are three numbered slots on the top right of the Hero screen that allow you to activate the heroes into different slots.

Each Hero
Here the list of all the Heroes with their respective prices and abilities. The X and Y values are dependent on the Hero's level.

Each active ability has a cooldown period, which ranges from about three to ten minutes for several hero abilities.

Energy will regenerate slowly when camping, fishing, or being away. The War Tortoise Evolution, Stamina, will increase energy regeneration to +0.04/s Energy, or one Energy every 25 seconds. ''*The Xs,Ys, and Zs here are determined by your heroes' level. The game is too new to get the formulas for them yet :/''

Leveling Up
Your hero earns experience points (xp) while they are in battle. Once they are ready to level up, you can tap the star icon that appears on the right of the battle screen to do so. You can also hit the level up button under their name.

Heroes earn more xp on harder levels. A red XP icon floating over your hero or pilot indicates that they are too high-leveled for the current level to gain xp. Switch to a lower-leveled hero to have them gain xp faster.

Abe's Pilot ability to increase xp gain of Active heroes can really help level your Heroes faster. The Evolution, Experience Boost, on the Heroes tab can also help heroes and pilot gain experience up to 500% faster.

Veterancy
Veteran level is what it costs in Gems to increase the max level of the hero. The hero will not continue leveling up when it hits the level cap until after you upgrade its veterancy. Each increase in minor Veterancy level comes with a x10 damage bonus, and a major Veterancy level comes with a significant damage bonus. After each major Veterancy level upgrade, the hero's level is reset to 1. Each hero level (1-1000) gained comes with a small increase in both their active and passive skill values. Here are the stats for each level:

Rested State
When a Hero is not active, they charge up to Rested State. Once active, rested Heroes earn x10 XP and deal Xx damage (bonus based on Veterancy level). Heroes on quests are considered to be resting.

The Evolution, Deep Rest, will increase the rested time for heroes and pilots by 100%.

Mastery
When a Hero's level is 600 and they have a Veterancy of 5, they become Mastered. Mastered Heroes' passive abilities are active all the time, even if the hero themselves are not.

Ex: I have Bones mastered, so even though I have One Eye, Garrison, and Ringo equipped as my active heroes, I still have the chance for enemies to be revived and fight for me.

You can have all heroes mastered.

Formulas and Maths
Here are the formulas we have now:

Base damage value = 300 * damageRating + (damageRating^2 * 100.0)

''*If you notice in this formula, the damage rating of the hero actually matters a hefty amount. So, generally speaking, heroes with a higher damage stat will do more damage''

Upgrade damage = level * 4.0 ^ int((level-1)*0.1)

Veterancy = 10^(veterancy level-1)

Quests
Heroes that are not active will go on quests. There are two types of quests: easy quests and hard quests. Easy quests can take 3-10 minutes, and have small rewards, like cash or experience for the hero. Hard quests take 12-24 hours, and have large rewards, like DNA, Gems, XP, and a lot of logs. You can check how much time and the difficulty of the quest (easy or hard) under the hero menu area. There is a cooldown after a hero completes a quest, which is indicated by the timer being red. If you want to switch the hero to a different difficulty of questing, you will not get the rewards from the partially completed quest.

Adventure Lands
In Adventure Lands, the Hero Summon flag can be used to summon one of your randomly-selected heroes to help your Adventurer. Multiple heroes can be summoned (maximum three simultaneously?), and leveled up via Hero Upgrade flags or Adventure Upgrades purchases with coins. Heroes in Adventure Lands have limited health and can be killed by enemies, though they can be healed by capturing a Camping flag.

Some tips
Always attempt to buy heroes with their discounts after their free trial, it will save you a lot of Gems. Hero free trials come around again if you miss them the first time. Also, make sure that your heroes are active instead of on a quest, and make sure you have at least one ranged hero, as aerial enemies are annoying.

Ahap's passive money gaining ability will help you earn lots of money quickly.
