In Dawn of Titans the Arcane Tower allows you upgrade your spell levels and take more spells into battle.
Upgrading your Arcane tower will unlock higher spell levels and additional spell slots on your titan. You first have to unlock the spells in your Spell Forge before you can upgrade their power.
Upgrading spells costs gold and in turn causes the spells to cost more gold to make. You can check out the cost and benefits of upgrading each spell on our Spells Page.
The Arcane Tower is one of the final buildings to be unlocked at Castle level 9. It is also one of the most expensive buildings to upgrade. You are required to upgrade your Castle and Spell Forge in order to upgrade this building.
The table below has the build cost for each upgrade level, build time and buildings required. The table also shows the spell level cap you can reach and the number of spells your titan can take into battle.
