Task Reward, Radiant Crystals?

[Esildor]

Not really sure where to put this, didn't think it belonged in the quest folder.

Made a Task on the EoC tasks window .. it's functioning perfectly but I'm wondering if there's a way to make it reward radiant crystals? I know I could put single item reward in and have it reward A radiant crystal but I want my task to give 40 of them.

As my workaround to this issue I planned on having the task reward everyone(group) a "voucher" and then the voucher can be handed in for 40 radiant crystals.

Would that be the easiest way to do this or is there a way I can have the actual task reward radiant crystals?

Thanks!
