Getting Three Stars in Kingdom Rush Origins: Redwood Stand (Level 4)
In the Redwood Stand level, you'll get access to your first level 4 tower of the game: the Arcane Archer. The great thing about level four towers are their special abilities. Once you've built your tower to level 4, tap it and two options will appear. For the Arcane Archer tower, those will be Slumber Arrows, which put your enemy to sleep temporarily, and Burst Arrows which explode and deal area damage.
Placing Your First Towers in Redwood Stand
Below is an example of how I like to place my first towers in this level. The barracks are located so they can stop enemies from either path with a druid opposite to deal area damage to all stopped enemies. Placing mages on either side of the tree makes sure I'm dealing damage as enemies enter and exit the tree.
That broken-looking tower at the end of the path can be fixed for 100 coins. Once you fix it, you can recruit up to four Awoks to help you. They act similarly to barracks and can be repositioned along the path. They are great as you get into later, bigger waves in this level. You'll also notice two Awoks in the big tree. They throw spears at your enemies, but you don't have any control over those ones.
New Paths Are Cut Out
In Wave 5, a connecting path is added. With this new portion of path comes a new spot to build a tower so it's not all bad. I usually place barracks here and rely on my other established towers for real damage.
During Wave 10, you'll notice a new path from the left is cut out. Knowing this ahead of time can help you plan where you want to put your towers in preparation for this. I like to put barracks near where the new path meets the old to stop enemies coming from this direction. I also like to put an archer tower there and upgrade it to level 4 because I like the range of its attack.
New Enemy: Gnoll Blighter
These guys can be tricky because they will render the Magic Blossoms near them useless. They also summon up little purple demon dogs that can attack your soldiers, reinforcements and hero. I like to take them down quickly with my lightning.
New Enemy: Ettin
This new enemy is very slow but he can do a lot of damage! I like to use special powers to take these guys down before they kill all of my soldiers! Don't let these guys get through because each one will cost two hearts and jeopardize your ability to get three stars on this level!
This level isn't too hard if you know to expect the two additional paths and use everything wisely. Don't forget about using your Magic Blossoms, and don't be afraid to utilize the Awoks, even if it seems expensive. Move your hero around to different locations when needed.
