===2000–2003: ''Undeceived'' and ''Synergy''===
Extol returned to the studio in December 1999 to record a follow-up album. In June 2000, their second studio album, ''[[Undeceived]]'', was released. The release saw their music become "harder and darker" than their previous work, opting to move towards a [[death metal]] sound. The song "Ember" proved to be a popular song among their fans.

In 2001, another EP, ''Paralysis'', was recorded; it was only released in Sweden.  This EP featured a cover of "Shadow of Death" by the American thrash metal group [[Believer (band)|Believer]], whom the band considers to be a great influence. After ''Paralysis'', Glidje left the band to focus on his other project, Ganglion, and Børud returned to the line-up.<ref name=":4" /><ref name=":1"/> After ''Undeceived'' was released, Extol was no longer obligated to Endtime Productions, and they signed with [[Century Media Records|Century Media]] in 2002.<ref name=":4" /> Their album, ''[[Synergy (Extol album)|Synergy]]'', released in 2003, showed an even greater appreciation of the band Believer and their style of thrash metal. Following the release, Extol toured Europe and US with the Swedish progressive death metal group [[Opeth]].<ref>{{Cite web|title=Century Media Records - Extol: : On tour with Opeth!|url=https://www.centurymedia.com/newsdetailed.aspx?IdNews=3450&IdCompany=3|access-date=20 April 2021|website=www.centurymedia.com}}</ref>
