Gathering in SB worry, HP/ def/ GP scaling. Deep vigor reexamining?

[Hamada]

Deep Vigor is meant to be used with the other ability you get at 25.

It's also good paired with Luck of the Mountaineer/Pioneer.

1100- 1350 gp is what you need before it becomes worth using.
Also you need a +1 node and 300 gp to make it work outside leves (not worth it)
for the last line no it is not, you are better off with blessed harvest II + leaf turn + field mastery

I forgot about ageless words, that ability is even more useless then Deep Vigor is. See how useless it is? It is so unused I forgot it's existence to complain about it.
