While it allowed you to collect Ioptons and Tempotons through your professions in the Hall of Valor, the NPC Halvari Sendor has been deactivated until the next maintenance of DOFUS Retro Temporis. A blessing in disguise: this decision was made to limit a loophole in obtaining Ioptons.
If you’ve never dealt with him (or at least if you don’t remember), he allowed you to get Ioptons when you came to talk to him with a profession at level 100. Except that, not lacking in generosity, the NPC offers you Ioptons for your first 6 level 100 professions… But also each time you forget a profession and raise it again to this level. So it was possible to get a large amount of looping Ioptons just by mounting your trades.
Far from the will of the GDs of the game, this Halvari Sendor has therefore been deactivated until the next maintenance. To know Wednesday, February 16, 2022. A decision that also calls into question the success of the first quest you get when you arrive in the Hall of Valor. Don’t panic though, chat with this NPC is auto-validated when you enter the map.
