Tree of Youth

When you finish casting this spell, the tree you used for this spell absorbs the Goodberry and diamond encrusted golden apple. The now enhanced tree produces 10 Goodberries every day at dawn. Unpicked berries wither and fall off the tree after 24 hours. Additionally, anyone that attempts to retrieve the berries without the assistance of the trees sentries must pass a DC 16 sleight of hand check. Failure causes the creature to take 4d4 slashing damage and gives the Poisoned Condition until their next long rest (unless they remove it through a spell or item).

The tree has the following additional effects:

Golden Berry: Berries taken from the tree heal 20 hit points and have the added effect of preventing a creature from aging for the next 24 hours. 

Idunn's Sentries: This tree is protected by 4 Wood Woad’s who can gather berries for you without risk of harm and will defend the tree from anyone that seeks to steal it's berries. The Wood Woad’s fight until they have driven off or slain the intruders. They also obey your spoken commands (no action required by you) that you issue while in the area. If you don't give them commands and no intruders are present, the Wood Woad’s do nothing.

After 7 days the tree looses its magic and reverts to a mundane tree. You can reinvigorate the tree by casting this spell on the tree again and so long as it has not been removed from the magic soil, you can recast this spell without any additional material components. However, when you cast this spell somewhere else, you will require new material components. Casting this spell a second time also causes the first tree to wither and sink back into the ground.

Casting this spell on the same spot once every 7 days for a year makes the tree permanent.
