Hi there, best advice is already given by several others like Hoeroesflorian, make sure to get your third troop and spell slot if you didn’t yet do that.
As a great tip I can tell you this for offense, there are three kind of spells and to become great it’s best to have one of each category in your arsenal while attacking (at lower levels not needed, but later you will be reminded on my story, because then it’s a must). The spell categories are
- defensive (heal/shield)
- instant (hammerstrike/blizzard/swordrain)
- lasting(Sonic Blast/Blade Storm/Firestorm).
Of course there are other spells like poison, stun and so on, but at higher ranks the spells I mentioned are used most often. At your level I would concentrate on upgrading one or two of each category.
I suggest you to use defensive spell shield. Shield is way better than heal, reasons are explained in details by Heroesflorian in another topic. For the rest I would focus on lasting spell sonic blast and instant spells like blizzard (long range and doing massive damage when maxed) or hammerstrike (very short cooldown).
At your level bladestorm will still be a good choice to have in your arsenal when it’s upgraded a lot, also swordrain and firestorm are good choices. Bladestorm whipes out troops and barricades with ease, so at lower levels it’s a good choice. But like I said, try to focus on at least one spell out of each category. At higher levels combinations of shield, sonic blast and blizzard (sometimes hammerstrike) are common used.
Troops are very important to upgrade. When upgraded, they improve offense and defense. So keep that in mind. And to be able to upgrade them the castle gate needs to be improved. Spells are for offense, so upgrading them will help you to beat stronger players, but… when your defense is staying behind, expect to be attacked often. So don’t forget to improve your defense. How?
Well… When I look at your defense wave levels, I would say try to focus on constantly upgrading a wave and lay the main focus on first five waves, since they come back twice. In the beginning it looks just like wasting gold to improve only two morale points for every upgrade, but you need to see the complete picture. It takes endless time to upgrade your waves to high levels. Since you can only improve one wave at a time, don’t forget it’s important. The stronger your waves, the harder it becomes for raiders to beat your base. And the more morale points a wave has, it can hold more and stronger troops and even monsters.
Which troops to improve first? Basic troops like knights, archer and froster are important to upgrade. Later in the game you will need arblaster and canons, but check what you are feeling comfortable with. At lower ranked levels paladin is still very handy, but when opponents start to attack with mummies or blazing knights, they become pretty useless.
Defending troops need support. And that support is delivered by towers. Troops slow down raiders and towers do massive damage to them. Your objective must be to slow down or kill the hero, take out troops and make sure they can’t make it to beat your base in time. Don’t forget to upgrade towers, since lower levels are quite easy to destroy and don’t support your troops like they do at higher levels. To prevent them from being destroyed easily, you must place barricades on the right spot. Then the picture becomes clear. You need to build a great base design where all comes together, barricades must be placed well so that an attacker can only take down one at a time, towers must damage attacking troops. A good placement makes sure they do a lot of damage while hero can’t take a lot of them out with one spell.
Using a snake tower just before a skull tower is a great choice for example. Heros without shield take damage from the snake tower while a skull tower is firing skulls to destroy troops. So they lose precious time. And even with shield it can be dangerous. I also often got hit by a skull that just destroyed my shield while I was taking a shower under a snake tower. there are videos out there that teach you a lot. I would recommend you to watch them. Even the best base designs can be found there.
