School of Alchemy

This is a class I created for one of my friends to play at a table that I am running that starts from level 3. The ideal would be to create a new class instead of a subclass but I believe it was fun to play and with several options to build your character. The value of the flasks varies between 10gp until 5.000gp on my table. Sorry for any english erros but its not my first language.
The idea of this class is to be a kind of user of magic but with additional effects such as increased area, increased damage, versatility between healing and damage, having elixirs that increase attributes, strengthening an ally with resistance in some element or weakening an enemy with the same element.

Tool Proficiency

When you select this specialization at the 3rd level, you gain proficiency with alchemist's supplies. If you already have this proficiency, you can choose another artisan tool.

Emergency Potion

You make a chemical reaction so fast in your portable cauldron that there is no time to put it in the bottle, but its damage and effect are random.Choose the target to attack, roll the attack and then roll to know the damage and then roll to know the effect.

For more information on damage and effects, check the characteristics of this class "Potion Preparation".

If you fail to try to hit a target, but it is not a critical failure, the emergency potion will melt during the path and no one will be affected.

If you make a critical failure when you roll to attack, the Emergency Potion ends up bursting at you, roll the damage and effect.

Your potion attacks use your intelligence modifier to hit with the following formula.
Potion attack: your proficiency bonus + Intelligence modifier + other modifiers that contribute to the hit.

Potion Preparation

Starting at the 2nd level, you can prepare your potions as shown in the Potion Preparation table. You have a maximum of 10 spaces for potions. There is the possibility to mix the size of the bottles according to their spaces:
A small bottle takes up space and causes damage and an effect.
A medium bottle occupies two spaces and causes one damage and two effects or two damage and one effect.
A large bottle occupies three spaces and causes two damage and two effects.

When you reach certain levels in this class, you can make more potions: 20 spaces on the 6th level and 40 spaces on the 15th level.

Roll separately for each potion's damage and effect. Each potion requires its own bottle.

Potions when selected with the resistance effect do not generate damage against the allied target (s), only the effect.
Resistance and healing potions should be done as follows:
A normal attack to try to hit your ally with only half the AC of the target rounded up.
If the attack action fails, the target must make a save of dexterity to try to catch the potion during its trajectory and receive its benefit.
On a critical failure, the potion erupts at the alchemist.
The user's DC for the dex save should be considered as a difficulty.
DC formula: 8 + your magic skill modification(int) + your proficiency bonus + any additional modifications.
The ally can make the test to dodge the range of action of a harmful potion, it will be a save of dexterity against DC to resist.
Having success will have no effect. Failure will take the same damage as the original hit target.

Chain reaction

At the beginning of level 10, critical strikes allow you to choose to roll additional damage or an additional effect.

Critical flaws are required to roll additional damage or an additional effect. The choice of which will be up to the player.

Other specializations can be used in this case. Example: Player attacked and obtained a critical failure, so he chose to receive an additional effect. However, he has the expertise to remove an effect. Chose to remove the option from the area as it was close to other allies, rolled 1d6 resulting in 2 so the additional effect was weak.
