Theons are character bound and appears not transferable or sold to other players at this time. Theons also cannot be exchanged for goods at this time according to my source-
At some point in spring, the Pantibian Festival will take place. This is an opportunity to meet the four founders of Tibia, Stephan, Guido, Durin, and Steve – commonly known as the Gods – ingame and play Tibia with them. The Gods will spend 45 minutes on each of three special game worlds (one per region), which are only available during this event, to beat a fun obstacle course together with the players.
The final date for the event has yet to be chosen, but it will take place during a workday (i.e. Monday till Friday) in the evening (CET or CEST), and at the latest at the end of May. From around the time the Pantibian Festival takes place, both qualified and non-qualified players can also exchange their Theons for deco items which can be gained during the 25 years festivities
You can check the amount of Theons you have by viewing your quest log under "25 years of Tibia" quest. Theons can be earned in numerous ways. I'll paste information from my source, how can I earn theons?
Theons is a collective points system (similar to Orcoberfestival or A Pirat’s Tail Quest) which can be collected during Tibia’s 25th Anniversary - from 7th January 2022 until it’s February 2022.
Theons can be collected by:
- Minibosses in the dungeon and boss Lord Retro- every 20 hrs per character / Minibosses sets of 50 Theons (can be few stacks), Lord Retro- 7k points - loot vary for Lord Retro +/-
- Funfair with Dragon Hatchling - once per day per character- 100 Theons (vary, depends on how lucky you are)
- Birthday Buffet- every 24 hours per character- 25 Theons
- By Scavenger Hunt with tourists every 20 hours.- 200 Theons
- Killing monsters during raids in Svargrond, Liberty bay and Port hope- - 1 Theon per monster
- Killing monsters in the dungeon - 1 Theon per monster
The benefits of Theons are:
- Opportunity to play with Gods! ( Stephan, Guido, Durin, Steve) by collecting Theons.
- New Highscore Pantheon- By collecting Theons
- Exchanging them for deco items.
