THRONE ROOM

Upgrades

Upgrading structures is one essential element of Royal Revolt 2. By upgrading towers, buildings, troops, and spells, you are able to get stronger, allowing you to defend your own castle and raid others successfully.

Shield

The Shield is best used when attacking with a huge army and gives you an enormous advantage in pitched battle.

Blizzard

The Blizzard slows down every unit and deals damage to your opponents. A magical mixture of two beneficial ingredients.

Heal

The Heal allows you to heal your troops from damage, fire, and poison. Depending on your strategy, this one could be a very strong spell.

Swordrain

The Swordrain is maybe the most effective weapon against units and has the biggest range. Be sure to have it in your arsenal.

Firestorm

The Firestorm burns everything and can be used to great effect against units and building, but is weak when unleashed against Blockades.

Stun

The Stun is best used when your opponent is stronger than you. Use it when you’re at a disadvantage.

Toxic Cloud

The Toxic Cloud is heavily effective against troops and best used against huge armies.

Hammerstrike

The Hammerstrike is effective against both units and buildings. Always a useful addition to a more specialized pool of spells.
