Reapers

A harmless looking tree can be the end, if a traveler isn't aware of this danger. Reapers are trees, occupied by evil spirits, transforming them in death-traps. Reapers are either rooted to the ground, or can only move around slowly. But they make up for this with their long, tentacle-like branches and their strong magic spells, which can spell doom for everyone near. But since its body is wood, fire will destroy a Reaper very fast.

They can be found mainly in forests, especially Spiritwood, but also dwell within dungeons. They hoard great treasures and are excellent hunting for those looking to raise funds.

These deadly creatures first plagued the dungeons of Sosaria in Ultima I. Referred to as "tanglers" at the time (not to be confused with Tangle Vines!), they did not then display any magical ability. Since re-appearing as Reapers in Ultima IV, they changed very little in future Ultima installments. The only difference is their occasional mobility, which is explained as being a very brief part of their life-cycle.
