Reward object in Quest

[nvnamsss]

Is it useful when I completely separate Quest and Reward into 2 Object instead of 1, as my expectation, I would like to add more Reward to Quest in a easy way instead of pre-define.

How to do it? I thinked about Tuple but look hard to handle when we work with other system due to I want my Quest definely don't care about how reward is processing, Quest just need to release data of Reward, then another system will do the rest thing.

Could I using Tuple for release data?
