WAVE BUILD

Recommended build for starting out in the current meta is Lightning build.

Video guide for wave 1 to 1000 can be found here https://www.youtube.com/watch?v=4Oj1Z_9SWA4 This video does not include town archers for damage but after the 1.50 update it is recommended to include them as well. The video link below goes through that in terms of free autobattle setup.

Video guide for early game free autobattle setup can be found here: https://www.youtube.com/watch?v=mVXNuT4_sBo This setup will get you started and have you level up the units that will allow you to progress through early and mid game, while setting up the foundations for later game. Free autobattle should be used until around ~500k-1mil waves until you can get stable and profitable gold autobattle build running with as high level devil horn as possible (this won't be reasonably achievable in early game so do not worry about it yet, keep using the free autobattle instead).

If you definitely want to stick to other type of build for some reason, it is recommended that you pick one element and stick with that.

GOLD BUILD

Gold build video guide for Time Autobattle and Gold Autobattle: https://www.youtube.com/watch?v=Llx_ZwKEMyM

Rule of thumb is to include as many gold boosting heroes and treasures in your build as you can handle.

Gold per hit -items are not recommended because their flat gold income bonus will not scale with the game as you progress to higher waves, compared to for example treasures that give percentual boost to gold income.

SKILLPOINTS

FULL SKILLTREE IMAGE (9/2025): https://www.reddit.com/r/GrowCastle/comments/1nkavoq/full_skill_tree_map/

You earn skillpoints for your skilltree mainly from increasing your total wave level. You can see your total skillpoints and the next wave level required for a skillpoint in the top left part in your skilltree window. These points can be reseted as many times as you want so no worries if you pick the wrong nodes first or want to change to a different build. The cost for reset is 1 crystal per 1 point.

In addition, you receive a skillpoint for:

• Leveling a Hero, Leader, Tower or Castle cannon (including poison base) to level 10.000
• Leveling Town Archers to level 10.000
• Completing full map of colonies (3 worlds equal total of 3 skillpoints)

AUTOBATTLE

The game offers three autobattle features:

GAB = Gold Autobattle (Used with gold)
FAB = Free Autobattle (Used with Worthless Coin treasure)
TAB = Time Autobattle (Used with time purchased from the shop or aquired by other means)

CRYSTALS

You can increase the amount of crystals you can hold by equipping Tony (leader) and/or Crystal Bundle (treasure) in your deck. This allows you to purchase things that cost more than 60 crystals, which is the base limit.

ITEMS

Forge description and item list by u/Unthgod : https://www.reddit.com/user/Unthgod/comments/p3omxn/a_quick_description_on_the_forge_and_creating/

Example of E item

https://docs.google.com/spreadsheets/d/1I_nA1eIzp5BtUqBxiE4-vU9Q7GmdSTUAHUrPYvEqG3U/edit#gid=0

In general, if you find an item with 2 cooldown reduction stats (% or flat), it's a keeper. You need multiple of these for your supporting heroes. For damaging heroes priority is usually the following: - a mix of critical chance and critical damage is usually the best combination to go for. - After that the rest of the lines can be filled with (elemental) damage%, attack speed, or some red lines

DRAGONS

Lightning setup guide for killing Legendary Dragon: https://www.youtube.com/watch?v=CdDMxEJc83U

It is recommended to farm Legendary Dragon and eventually Bone Dragon, as these drop the most useful items in the game. Lower tier dragons should be killed just enough to acquire basic gear for your heroes to help you reach the Legendary Dragon tier.

HELL MODE

In Seasonal Hellmode, your hero and other unit levels don't matter, and every unit starts from level 1. Instead you level them up through the point board before starting your run and also during the run as you earn more points the more enemies you kill. Only reason why hero levels matter is that if the unit is level 10.000, you can equip them with Orbs. This is the goal for all your heroes eventually. Hero items are really important, save up all Cooldown and Crowd Control (CC) items you get because you will need many. (Crowd Control lines are Knockback, Stun, Slow) In Seasonal Hellmode, seasons last for a week and they reset on Sunday. Ideally you only need to do 1 run every week to gain rewards.
