New permissions in game but no documentation

Hi! 
Love the plugin! 

I was going through the permissions in game and I noticed there are new permissions for Epic Loot that I can't seem to find any information on. 
In the description of this plugin page, it lists a number of permissions,  but there are some missing: 
Skilltree.1 through skilltree.5
default   -   if use and craft are enabled, what does default do? 

Any information on this would be greatly appreciated! 

If it's not documented it generally means that it's used by another plugin.

In this particular case, the skilltree.1-5 are used by the Skill Tree plugin to provide higher chances of finding epic loot, as EpicLoot provides a new node into Skill Tree.

Aaaaah okay, that makes perfect sense. 
Thanks a bunch!!
