School of the Manticore

Hailing from the far east, school of the manticore witchers rely on their alchemical creations more than their blades or signs.   A manticore witcher is highly skilled at potion creation, able to apply them faster and elicit effects from them that other witcher schools cannot.  Some of the most skilled among them are rumored to make potions that seeming last forever.  Manticore witchers are also skilled bomb makers and are highly proficient in their deployment.  Finally manticore witchers have access to recipes for special decoctions that they can attune to giving them powerful buffs and abilities.

School of the Manticore Techniques

You have trained as a witcher of the school of the manticore and learned the ways of alchemy and bomb making.  The ingredients for potion and bomb creation is one less than typically required.  When you would use your quick brew witcher feature on a short or long rest to create an item, you may expend the necessary ingredients to create another.  .

Side Effects

You have mastered ancient witcher recipes and found diagrams that have revealed information few have access to. Potions and bombs can now be used as a bonus action instead of an action. All bombs do 1d4 extra damage including bombs that normally do no damage; the damage type is force. All potions now heal you for 1d4 healing on top of their normal effects when consumed.

Distilling Decoctions

You can now create decoctions from ingredients taken from powerful monsters.  The ingredient requirement for these items includes the normal ingredients as well a special one taken from a powerful monster.  Once acquired when you would use your quick brew feature to create a potion or bomb you can instead create one elixir.  Roll on the random elixir table to determine its effects.  Elixirs once consumed last until another is consumed or the drinker dies.  Elixirs require an attunement slot.

Fast Metabolism

Through careful research and practice you have developed far more potent potions better suited to your fast metabolism. You have also applied a similar approach to bombs for a bigger boom!  Potions now have double the duration and healing.  Bombs also now do double damage and last twice as long.  This effect stacks with your side effects feature.

Tissue Transmutation

Through trial and error and some self experimentation you have grasped the art of making elixirs.  When expending the resources to create an elixir you now create a second one for free.  You also can choose which elixirs to make and have the ability to attune to two instead of one. 

Master Alchemist

Through relentless field study, trial and error on the path you have achieved a level of mastery few could dream of.  You can now make potions and bombs far more powerful.  The damage and duration of your bombs doubles again.  Your potion's healing and duration also does the same.
