Nature monk (Not playtested yet)

This monk focuses on the relationship between inner and outer ki. This Monk makes use of nature to assist and battle and even makes use of the druidic magic. 

One with Nature

At 3rd level your training within nature has granted you 10 ft of tremorsense. This range increases to 30 ft at 17th lvl. 

Spellcasting

You are able to cast spells using the druid spell list. 
You are a 3rd caster. (Using arcane trickster progression)

Ki Enhanced Spells

When you cast a spell using a spell slot, you can expend 3 ki points to upcast the spell, increasing its effect as if using a higher-level spell slot. However, this does not grant you access to a higher-level spell slot—your original spell slot is still expended as normal. Instead, your ki substitutes for the additional magical energy required to enhance the spell’s potency. Alternatively, you can convert spell slots into ki. As an Action you regain a number of ki equal to the spell slot lvl -1 (minium 0) when you convert spell to ki. 

Natures Strike

When you hit with a flurry of blows attack an thick vine or root sprouts out suddenly to grab your foe. The creature must make a dex save against your monk dc or be restrained. 

Wrath of Nature

You take an action to call upon nature itself to assist you. For the next minute a 30 ft enimation (30 ft surrounding you) occurs that causes diffucult terrain to creatures you choose. the creatures take 1d4 dmg for every 5 ft of movement within your range. Wild wind also surrounds you within this range blocking range weapon attacks for you and allies withing range. Spell ranged attacks have disadvantage against you and your allies within this wild wind.  You can use this action once for free per long rest, with every use before then costing 5 ki points.
