Igniting Spark

Starting at 3rd level, you wreathe your strikes in fire. Whenever you make an attack with an unarmed strike or a monk weapon, you can choose to deal fire damage instead of the normal damage for that attack.
If you hit with a melee attack and deal fire damage this way, you can spend 1 ki point to ignite the target for 1 minute if it's a creature.
At the start of each of its turns while ignited, a creature must make a Dexterity saving throw against your Ki save DC. On a failed save, it takes fire damage equal to one roll of your Martial Arts die. On a successful save, it is no longer ignited.
If the ignited creature or a creature within 5 feet of it uses an action to put out the flames, or if some other effect douses the flames (such as the target being submerged in water), the creature is no longer ignited.
You can only have one creature ignited in this way at a time.

Weave Fire

Also at 3rd level, you can channel your ki into magical flames.
You gain 2 cantrips of your choice from the following list, and can cast them at will. You gain another cantrip of your choice from the list at 11th level, and you gain the last remaining cantrip at 17th level.
Whenever you take the Attack action on your turn, you can spend 1 ki point to cast one of these cantrips in place of one of those attacks. You cannot replace multiple attacks in one action. Starting at 11th level, you can choose not to spend ki for this ability.
Wisdom is your spellcasting ability for these spells.

You regain all your expended Flame Burst dice when you finish a short or long rest. In addition, whenever you spend ki to cast a cantrip as part of your Attack action with your Weave Fire feature, you regain a Flame Burst die.
You can use your Flame Burst dice in the following ways:

• Once per turn when you hit with an unarmed strike or monk weapon, you can expend a Flame Burst die and add it as extra fire damage to that attack's damage roll.
• Whenever you make a spell attack for one of your Weave Fire cantrips, you can expend a Flame Burst die and add it to the attack roll.

• You can move through a space as narrow as 1 inch wide without squeezing. In addition, you can enter a hostile creature's space and stop there.
