How to beat any map with 3 Stars using 1 or 2 towers.
Towers
Info: You have to complete few first levels to get "Barracks" upgrade.
So basically at the begin of battle you will buy Barracks and upgrade them to Forest Keepers, after you got like 2-3 barracks with them, start to upgrade their Spears abillities (Very important) they are really OP when they got those Spears maxed.
Ancient Oak Spear
After few round you can add Bomb tower and upgrade it to "Arch-Druid Henge".
Use Bears as upgrade for them.
Some photos how it looks like (with 0 hp lost):
Strategy
This strategy is only about positioning, your Forest Keepers are good in Long distance so put someone in front of them to tank damage and you can win any round because their spears can kill like.
Bandersnatch
Twilight GolemIn few seconds so Arch-Mage bomb towers combined with "Bear summon" are best for them!
About Skill Tree
You should first upgrade your:
- Reinforcements to Lvl 3.
- Barracks lv 2.
- Thunderbolt to max.
When you got these upgrades then put Reinforcements to max and Barracks to max.
My personal favourite heroes are: Arivan [Elementalist] and Faustus [Dragon Mage].
