Gathering Higher level nodes, what level can you gather it at?

[Johnist]

For a Botanist you will need the Proper item (Main or Sub) and be a maximum of 5 levels below the level of the harvest.
Example:
Level 1-4 can only harvest Level 5
Level 5-9 can harvest Level 5 and 10
Level 10-14 can harvest 5, 10, and 15
Level 15-19 can harvest 5, 10, 15, and 20.

There is also an ability that is gained at a specific point to find 'Legendary' Harvest spots.
