Arm of the Wilds

This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. While holding it, you have a +2 bonus to spell attack rolls.

The staff has 10 charges for the following properties. It regains all charges daily at dawn, if the attuned creature is under a tree or in a forest.  When this Staff runs out of charges, the wood it is made out of starts to rot and the leaves that cover and weave around it start to wither and die. If it is not recharged in 1d4 days, the staff loses all magical properties and turns into rotten splinters of wood. 

Spells. You can use an action to expend 1 or more of the staff's charges to cast one of the following spells from it, using your spell save DC:  Animal Friendship (1 charge), Grasping Vine (3 charges), Barkskin (2 charges), Commune with Nature (5 charges), Speak with Animals (1 charge), Speak with Plants (3 charges), or Tree Stride (5 charges).

Enrich the Land. In an area of 100 ft. around the Staff, the secondary effect of the Plant Growth spell is applied if the creature attuned to the Staff stays in that 100 ft. area for 8 hours or more. 

A creature attuned to this Staff gains proficiency in either Nature or Survival. If a creature is already proficient in both Nature and Survival, the Staff grants Expertise on one of them. If a creature is already an expert on both, no bonus effect is applied.

Notes: Bonus: Magic, spending a long rest under a tree or in a forest by a spellcaster
