Greenmage

Greenmages are the heirs to the ancient traditions of the wood elves. They are wardens of the forest, specialized in nature magic and also reliable bowmen, trained to survive without spells if need be — as is sometimes the case in the blighted ashlands. 

Restriction: Only elves should take this subclass unless there is a really good reason otherwise.

Level 3: Green Magic

Spells from the Druid and Ranger spell lists are considered wizard spells for you.

Level 3: Warden of the Land

You gain proficiency with Light Armor, Shortbows, and Longbows. You also gain the Archery Fighting Style. You are also trained to craft basic ammunition with Smith's Tools like arrows and bolts.

Level 6: Entangling Shot

Your arrows can transform into vines on impact. The target must make a Strength saving throw against your Spell Save DC or be restrained until the end of your next turn. You can use this feature a number of times equal to your Intelligence modifier (minimum 1). All uses recharge at the end of a Long Rest.

Level 10: Leaf Scales

When an attacker that you can see hits you with a ranged attack or spell, you can use your reaction to halve the attack's damage against you.

Level 14: Weakening Entangling Shot

When you hit a target with your Entangling Shot, the target has disadvantage on all saving throws until the end of your next turn.
