The Rift Codex

The Eternal Rift Defense wiki. Numbers come straight from the game's balance data and are rebuilt whenever it changes.

Towers

There are 13 towers you can build, plus the Rift Crystal, which stands on the map as an obstacle. Each one has five ranks, and most have three specializations and a cursed Ultimate.

How towers grow

Ranks and experience

Towers earn experience from kills, and from your hero and pet standing on them while waves run. A tower reaches Rank 2 at 100 XP, Rank 3 at 300, Rank 4 at 600 and Rank 5 at 1100. Each rank raises damage, range and hit points.

Specializations

Combat towers offer three specializations, each bought with 50 Technology. Research towers generate Technology every wave. Some specializations can also be unlocked through the Specialist and Support talent trees.

Cursed towers and Ultimates

Stand on one of your own Rank 5 towers and pay 1,000 gold to spin the Rift Wheel. It is an even 50/50. Land a skull and the tower gains its own Ultimate. Land a medallion and the tower transmutes in place into that tower type at the same rank, cursed with that type's Ultimate. Either way, you end with a cursed tower.
