the gain from the collection is always 50 skill levels. I meant, does the XP gain from Discoveries make a difference if you level from 441 to 450 or from 491 to 500?Your one impact will be on the basic xp you get from making an item. If level is to large you wont get any basic xp and only get the bonus for the first discovery. Would recommend craft up to 450 (will get some of this by making the foods they request) and then cash in the 5*10 rewards.
